Aerosol cans have become an integral part of our daily lives and various industries due to their unique design and functionality. 

In this blog, we'll explore the diverse applications of empty aerosol cans.

In the Cosmetic and Personal Care Industry

Haircare Products

Hairsprays are one of the most common aerosol - based products.  They provide hold and volume to the hair.  The aerosol formulation allows for an even distribution of the product.  With a simple press of the nozzle, a fine mist of hairspray coats the hair strands, helping to keep the hairstyle in place throughout the day.  Styling mousses also come in aerosol cans.  These are great for adding texture and definition to the hair, making it easier to create different styles like curls or waves.

Skincare Products

Facial mists are popular among skincare enthusiasts.  Aerosol - delivered facial mists can provide instant hydration.  Ingredients such as hyaluronic acid, aloe vera, and various plant extracts are encapsulated in the mist.  When sprayed onto the face, it forms a light, refreshing layer that soothes and moisturizes the skin.  This application method ensures that the active ingredients are evenly spread across the face for maximum efficacy.

Deodorants and Antiperspirants

Aerosol deodorants and antiperspirants are widely used.  The spray mechanism allows for quick and easy application under the arms.  The formulation in the aerosol tin can contains substances that help control body odor and reduce sweating.  The fine spray covers a large area, providing long - lasting protection.

In the Household Cleaning Sector

Surface Cleaners

Aerosol surface cleaners are highly efficient.  They can be used on a variety of surfaces such as countertops, tables, and windows.  The pressurized system in the aerosol can enables the cleaner to be sprayed in a targeted manner.  The force of the spray helps to dislodge dirt and grime, making it easier to wipe away.  Different types of surface cleaners are available, including those for general cleaning and specialized ones for specific materials like wood or stainless steel.

Air Fresheners

Air freshener aerosol cans are essential for maintaining a pleasant indoor environment.  They come in a wide range of scents, from floral and fruity to fresh and clean.  The aerosol design allows the fragrance to be dispersed evenly throughout the room.  A quick spray can eliminate unpleasant odors and create a more inviting atmosphere in homes, offices, and public spaces.

Oven and Grill Cleaners

Cleaning ovens and grills can be a tough task, but aerosol oven and grill cleaners make it easier.  The strong cleaning agents in these aerosol cans are able to break down grease and food residues that accumulate over time.  The spray nozzle can be directed into hard - to - reach corners and crevices of the oven or grill, ensuring thorough cleaning.

In the Industrial and Automotive Fields

Paints and Coatings

Aerosol paint cans are widely used in DIY projects and small - scale industrial applications.  They are convenient for painting small objects, touch - ups, or creating decorative finishes.  The spray nozzle on the aerosol can be adjusted to control the paint flow and spray pattern, resulting in a smooth and even coat.  Industrial coatings in aerosol form are also used for protecting metal surfaces from corrosion.

Lubricants

Aerosol lubricants are invaluable in the automotive and mechanical industries.  They can be easily sprayed onto hinges, gears, and other moving parts.  The aerosol formulation allows the lubricant to reach tight spaces and provide smooth operation.  This helps to reduce friction and wear, extending the life of the equipment.

Adhesives

Aerosol adhesives are used in various applications.  In the packaging industry, they can be used to bond cardboard or paper.  In construction and DIY projects, aerosol adhesives can be used for quick and temporary fixes.  The spray - on adhesive provides a uniform layer, ensuring a strong bond between the surfaces.

Aerosol products, because of their ease of use and wide range of applications, are increasingly entering various industries and people's daily lives. Aerosol products are divided into tinplate cans, aluminum cans and plastic cans according to their packaging, among which tinplate cans are the most widely used and the phenomenon of corrosion inside the cans is also the most common. 

Every year due to corrosion caused by the leakage of aerosol products through the cans of the phenomenon occurred from time to time, the loss is huge, because of the complexity of the cause, the empty can manufacturers, filling manufacturers, businesses, users can not clearly define the responsibility, often can not be concluded, each assessed part of the loss of the matter, in fact, the corrosion of the aerosol can be prevented through the standardization of formulations, processes, and do a good job of stability testing.

1. Types of corrosion

(1) Even corrosion

Such as alkaline detergent and no internal coating of tinplate cans inside the tin-plated layer in contact with the complete de-tinning terminated.

(2) Pit corrosion and perforation

Localized dissolution of the metal leads to perforation.

(3) Fracture corrosion

Top, bottom cover and can body connection, easy to form a stagnant area, the contents of the existence of electrolyte concentration effect, easy to cause crevice corrosion. 

(4) Electro-coupling corrosion 

Can body of copper welding weld, due to the destruction of the tin layer, copper and iron electrode potential difference, in the presence of electrolyte, contact and produce galvanic coupling corrosion, although the weld has a complementary protective layer, but the electrolyte can arrive at the surface of the metal layer through the protective layer, the formation of corrosion batteries, resulting in corrosion.

(5) Stress corrosion

Forming deformation of the stress exacerbates the distortion, causing corrosion at the cracks, such as aluminum cans.

(6) Sub-membrane corrosion

Under the organic film or in the surface treatment film under the metal surface of the horizontal direction of the expansion of corrosion.

Formulator in doing product stability testing, less concerned about the above classification, generally according to the gas-phase corrosion, liquid-phase corrosion, gas-liquid interface corrosion to describe, and according to these three phenomena to select the appropriate corrosion inhibitor, adjust the formula.

2. from the formulation design to prevent corrosion of aerosol products

(1) tinplate cans for oil-based (solvent-based) aerosol products

General pure solvent-based formulations, no need to add corrosion inhibitors, corrosion will rarely occur, but there are exceptions, if the oil-based LPG pesticide batch leakage may be the cause of kerosene or LPG raw materials mixed with a trace amount of water, filling into the product, moisture to make some insecticidal active ingredient hydrolysis or kerosene impurity reaction, the precipitation of acid substances leading to corrosion of the can.

Solution:

① Measure the moisture content of the raw material, ensure that the moisture content is less than 100ppm.

② Add some water-soluble solvents, such as isopropyl alcohol, ethanol, etc. to disperse the trace water in the oily solvents and LPG, to prevent gathering and settling at the bottom.

 (2) Alcohol-based aerosol products in tinplate cans

Early air freshener formulations consisted mainly of flavors, anhydrous ethanol or isopropanol, LPG or DME. General. There is no need to add corrosion inhibitors to these products, and if 95% ethanol is used, 0.1% sodium benzoate can be added.

(3) Water-based aerosol products for tinplate cans

For tinplate cans without internal coating, general water-based products, the best PH control in 7.0 ~ 9.0, according to the functional requirements of the product, choose to add 0.1-0.2% of the gas-phase and liquid-phase corrosion inhibitors, such as sodium benzoate, sodium nitrite, triethanolamine, ammonia, phosphoric acid dihydrogen amine, morpholine and so on. The use and dosage of sodium nitrite should be carefully selected, as it may be counterproductive if there are ingredients in the formulation that oxidize sodium nitrite to sodium nitrate.

For tinplate cans with internal coating, the product PH should be controlled above 5.5, but not to use DME as the ejection agent, because DME will dissolve the internal coating, causing it to flake off and not play a protective role, and the flaking of the internal coating may clog the suction tube, resulting in the product can not be sprayed.

When the PH of water-based products>10 or even PH 12 or above, strong alkali will make its tinplate cans without internal coating of the internal tin layer dissolved, the cans show a grayish-black, we call it “passivation layer”, this phenomenon is called “de-tinning”, is when the tin is dissolved, exposing a dark gray film. This phenomenon is called “de-tinning”, is when the tin dissolution, exposing a dark gray film of tin-iron alloy FeSn2, and strong alkali further reaction iron passivation into black, to prevent further corrosion. When a passivation layer exists, the product rarely corrodes through the can.

 

Selection of high-quality qualified aerosol cans, aerosol valves is an important factor in preventing product corrosion, because the regular manufacturers of tinplate cans selected by the raw materials are more compliant, the process of making cans will be more stringent control of stamping, slicing, internal coating, can body welding, two volume sealing and other process quality, the production of tinplate cans in terms of pressure resistance, airtightness and corrosion resistance will be more secure.In mgaerosolcan, we offer high quality aerosol tin cans.

There are currently over 200 types of aerosol products used in personal, household, industrial, agricultural, construction, fire protection, safety, medical and other fields.

The aerosol valve may not seem eye-catching, but it is of utmost importance compared to the entire aerosol product. It not only affects the sealing performance of the product, but also the spraying effect, and of course, the stability of the entire aerosol product. Therefore, how to choose the appropriate valve is worth everyone's attention in the development process of aerosol products.

If we look at the types of valves, aerosols are mainly divided into two categories: one-component packaging and two-component packaging (BOV system). The main structure of one yuan aerosol includes: aerosol can body, aerosol valve, outer cover, actuator, propellant, and raw materials. The main results of binary aerosols include: aerosol can body, aerosol spray valve, extra layer of aluminum bag, outer cover, actuator, raw materials, and compressed gas.

Valves usually consist of seven parts: sealing cup, outer gasket, inner gasket, valve stem, spring, valve chamber, suction tube, etc. Considering different materials, sizes, and structures, theoretically, valves can exhibit billions of different variations.

Therefore, how to choose the appropriate spray valve requires comprehensive consideration of the following factors:

Firstly, is it a one-component valve or a BOV valve?

The compatibility issue needs to be considered when mixing the material and propellant in a one-component aerosol formulation. When both the propellant and the contents are sprayed out simultaneously, it is easy to produce a situation where the propellant has already been sprayed out while the material remains, which affects the consumer experience. Cannot be used 360 degrees, can only be used upright or upside down. Volatile propellants (such as butane or dimethyl ether) have a geometric fold increase in pressure with temperature, and are classified as hazardous materials with strict requirements for transportation and storage conditions.

Without considering cost factors, BOV valves have many advantages, such as:

The contents do not directly come into contact with the aerosol can, providing protection for the raw materials;

Spray out in all directions to adapt to diverse consumption scenarios;

Before filling, the valve bag can be vacuumed or disinfected by cobalt 60 irradiation. The formula can reduce preservatives and allergens;

The pressure inside the tank is constant, the spraying is stable, and the residual material is low;

Using compressed air or nitrogen, the pressure remains almost constant with increasing temperature, and the requirements for transportation and storage are relatively low.

Secondly, the choice of material for the sealing cup?

The thickness of tinplate cups is usually 0.27mm, and the thickness of aluminum cups is usually 0.42mm. The application in the field of personal care products usually uses aluminum cups, which are more stable and less prone to rusting. The size stability of the tinplate cup is better, and it is not easily affected by the aerosol can body or sealing process;

Thirdly, the material of the gasket

Gaskets are usually divided into inner gaskets and outer gaskets, with various materials including butyl, chloroprene, butyl, chlorobutyl, nitrile, chloroprene, polyurethane, and so on. Shrinkage of the gasket will affect the fit between the valve stem and gasket, sometimes leading to leakage. If the gasket expands excessively, the valve stem hole of the gasket cannot be exposed when pressing the nozzle, which will affect the spraying efficiency. After repeated experiments, a mixture of 75% ethanol and 25% isopentane was used for gold testing, and the best choices were chloroprene rubber (NEOPRENE) and butadiene sodium rubber (BUNA), which were relatively stable.

Fourth: Valve stem orifice

Common sizes include 0.35, 0.4, 0.46, 0.51, and 0.61mm, and the number of valve stem holes is one of the determining factors for the ejection rate. There are also different series of valve stem air holes, including 1, 2, 4, 6, and even 8 holes.

Fifth: Valve side hole

The gas phase side hole is located on the valve housing and is located inside after the valve is sealed. It is mainly used to increase atomization effect, increase the stability of content spraying for some powder products, and increase the spraying of high viscosity products. There are both single hole and double hole designs.

Sixth: Dip tube length

At the initial setting, the valve length can be calculated as the total height of the aerosol can minus the set value. Then, through compatibility testing, confirm the degree of shrinkage of the dip tube in the product, and the final valve length should be such that the bottom of the dip tube is at the lower one-third of the half circle at the bottom of the can after soaking and stabilizing.

Considering that dip tube have a 3-6% expansion rate, it is crucial to confirm the length after compatibility testing. Of course, a straw design with oblique cuts can also be slightly helpful.

Paired with appropriate buttons, the selected aerosol valve can convey the characteristics of the aerosol to consumers. As a packaging solution for complex products, compatibility and stability testing are required to design stunning products!

 

Definition

2K aerosol cans are specialized containers that typically have two separate openings, each of which can be used to release or fill contents. This design distinguishes them from traditional single-opening aerosol cans.

--2k aerosol tin cans--	--1k aerosol tin cans--
	This can have a partition structure inside to prevent premature mixing of two different contents. They are only allowed to come into contact through specific operations when needed.

How to install and use?

The short valve is installed on the side filled with curing agent. Before use, press the black button to mix curing agent with spray paint, and then press the white nozzle to use spray paint.

 

The working principle of a 2k (two-component) paint can is to pack two different components (usually paint and curing agent) in two different tanks or chambers, mix them together through a specific device or operation when used, and then spray. Before mixing, the two components are independent of each other and do not undergo chemical reactions. When spray painting is required, the channel connecting the two components is opened by pressing the nozzle, rotating the pull ring, or other operation, so that they are mixed at the nozzle. The mixed paint will cure quickly in the air to form a hard, durable paint film.

Why Comfort Matters When You're Out in the Wild

Comfort is more than a fleeting convenience on a backpacking trip; it’s critical to maintaining physical and mental well-being. Without a proper sleeping pad, your body could suffer from sore muscles, pressure points, or poor circulation. Even if you’re exhausted after a long hike, without the right support, your sleep can be restless. A good sleeping pad ensures you get the rest you need, so you wake up feeling refreshed and ready to tackle the next day's adventure. After all, a well-rested hiker is a happier hiker.

How Ultralight Sleeping Pads Enhance Your Outdoor Experience
Ultralight sleeping pads strike a perfect balance between comfort and weight. These pads are engineered for portability, designed to keep you comfortable in a range of conditions while minimizing the bulk in your pack. The best ultralight pads don’t just save space; they offer advanced materials that pack a punch in performance, from lightweight air chambers that provide cushioning to advanced fabrics that offer both comfort and durability. When you’re counting every ounce, these pads ensure your sleep setup doesn’t become a burden.

What Makes a Sleeping Pad Ultralight?
Not all sleeping pads are created equal. Ultralight pads go beyond the traditional, offering superior performance without the extra weight.

Weight and Portability: The Key to Ultralight Gear
The key feature of an ultralight sleeping pad is, of course, its weight. These pads are often made with specialized materials, such as thin, high-density foam or lightweight synthetic fabrics, that provide support without unnecessary bulk. They can weigh as little as 8 to 12 ounces, making them a must-have for anyone trying to cut down on the weight of their gear. When you're hiking long distances or doing a thru-hike, every ounce saved can make a big difference in your comfort and energy levels.

Comparing Ultralight Sleeping Pads with Standard Models
When comparing ultralight pads to their traditional counterparts, the difference in weight is obvious. Standard sleeping pads, typically made from thicker foam, are bulkier and heavier, often weighing several pounds. Ultralight versions, however, focus on minimizing weight without compromising on the basics: comfort, support, and insulation. While they may be thinner and more compact, the latest technology and materials ensure they still deliver solid performance in a small package.

Key Features to Consider When Choosing an Ultralight Sleeping Pad
Picking the right ultralight sleeping pad involves more than just checking the weight. There are several factors that can make or break your experience on the trail.

R-Value: Understanding Insulation and Temperature Control
The R-value is one of the most important considerations for any sleeping pad. This rating measures a pad's ability to insulate and keep you warm. For cold-weather backpacking, a higher R-value is essential, as it indicates better thermal resistance. Ultralight sleeping pads typically range from R-Values of 1.5 to 6, depending on their insulation. When choosing a pad, consider your destination and the season. For summer trips, a lower R-value may suffice, while winter trips demand a higher value to keep the cold ground from robbing your body heat.

Pack Size and Compactness: Ideal for Minimalists
One of the major benefits of ultralight sleeping pads is how compact they can be. These pads often roll up or fold down into a size small enough to fit into a backpack side pocket. For minimalist travelers, the ability to fit a sleeping pad into a pack without adding unnecessary bulk is a game-changer. While traditional pads might take up considerable space, ultralight versions are designed to fold or roll tight and flat, making them perfect for those who value packing efficiency.

Durability: Balancing Lightweight with Toughness
While ultralight sleeping pads are designed to be portable, they also need to be durable. Many ultralight pads use ripstop nylon or durable TPU coatings to ensure they can withstand the rigors of the outdoors. However, it’s important to remember that ultralight often means less padding, so while these pads can handle a fair amount of wear and tear, they may not be as resilient to ng, so while these pads can handle a fair amount of wear and tear, they may not be as resilient to punctures as their thicker counterparts. Always choose a sleeping pad that balances weight with durability, especially if you'll be camping in rugged terrain.

Inflation Methods: Air, Foam, or Hybrid?
Inflation is another key consideration. Most ultralight sleeping pads are air-filled, which provides excellent weight savings and compressibility. Some models feature self-inflating foam cores, which combine the convenience of air with added foam insulation. Others are a hybrid, offering the best of both worlds. Air-filled pads tend to be lighter and more compact but may require an external pump or your breath to inflate. In contrast, self-inflating pads are easier to set up but can be heavier and bulkier than pure air pads.

Top Ultralight Sleeping Pads of 2024: Our Expert Picks
After testing several models, here’s a roundup of the best ultralight sleeping pads you can buy in 2024.

Overview of the Best Options in the Market
Which offers a fantastic combination of weight and comfort, and the Compact Lightweight Double Air Sleeping Pad, known for its exceptional warmth-to-weight ratio, an affordable option with great performance for minimalist campers. Each of these pads is well-suited to different backpacking styles, from lightweight to ultralight through-hikes.

Comparing Top Contenders by Weight, Comfort, and Features
Each of the best ultralight sleeping pads of 2024 comes with distinct advantages. For example, the Camping Ultralight Inflatable Sleeping Mat weighs just 12 ounces and provides exceptional warmth with an R-value of 3.2, making it perfect for three-season backpacking. On the other hand, offers great comfort and a very affordable price point, although it has a slightly lower R-value of 1.3, making it better suited to warmer climates.

How to Choose the Best Ultralight Sleeping Pad for Your Needs
Selecting the right ultralight sleeping pad requires thoughtful consideration of your specific backpacking needs.

Evaluating Your Specific Needs: Sleep Position, Camping Conditions, etc.
Consider your sleep habits—side sleepers might want a thicker pad, while back sleepers might prioritize a lighter, more compact option. Additionally, think about your camping conditions. Will you be trekking in warm weather or through cold, alpine terrain? Knowing how often you’ll be camping in extreme conditions will help determine the ideal R-value and thickness for your pad.

Understanding the Trade-offs Between Comfort and Weight
While ultralight pads offer portability and compactness, they might lack the plush, cushioned feel of heavier models. The trade-off often comes down to a balance between comfort and weight. If you're willing to sacrifice a bit of comfort for the sake of lighter gear, an ultralight pad is an ideal choice. But if you need a more comfortable sleep system, it might be worth considering slightly heavier options.
