In the packaging customization industry these years, I’ve seen quite a few troubles caused by wrong container choices — a chemical company used ordinary
Metal Cans to package acidic cleaners, and in less than a month, the cans rusted and leaked. Not only did they lose the entire batch of products, but they also almost caused safety hazards during transportation. Chemical products are far more corrosive than ordinary items; ingredients like acids, alkalis, and solvents will continuously erode containers. That’s why corrosion resistance must be a top priority when customizing
aerosol tin can.
Corrosion may seem like a slow process, but it hides fatal risks. It not only causes rust spots and deformation on
Aerosol Tin Can but also may penetrate the can body, leading to leakage of chemical substances. This not only pollutes the environment but may also trigger safety accidents such as combustion and explosion. More insidiously, impurities from corrosion may mix into chemical products, changing their composition, affecting use effects, and even causing quality disputes. So choosing the right corrosion-resistant
custom aerosol tin can is never as simple as “picking a box” — it’s like adding a safety insurance to the product.

Prioritize confirming coating material compatibilityDifferent chemical products require corresponding protective coatings, which is like putting a “protective suit” on the aerosol tin can. For example, strong acidic products are suitable for epoxy resin coatings, while solvent-resistant products are better matched with polyurethane coatings. When customizing, SAILON first conducts compatibility tests based on the product’s pH value and ingredient list to prevent the coating from reacting with chemical substances and failing.
-
Don’t “cut corners” on can body thicknessCan body thickness directly affects corrosion resistance duration and structural strength. In most cases, aerosol tin can for chemical products are recommended to use 0.25-0.35mm plates. For highly corrosive products, the thickness can be increased to more than 0.4mm. Too thin a can body is not only easy to be corroded and penetrated but may also deform during transportation bumps.
-
Sealing performance is the “second line of defense”Corrosion often starts from gaps — if the can mouth is not tightly sealed, moisture and oxygen in the air will seep in, accelerating internal corrosion of the can body. High-quality custom aerosol tin can adopt a double-sealing structure, paired with butyl rubber or fluororubber sealing rings. SAILON also conducts additional leakage tests to ensure a tight seal even in high-pressure and high-temperature environments.
-
Recognize authoritative test certificationsReliable aerosol tin can must pass professional corrosion resistance tests. For example, the salt spray test should last more than 48 hours without rust, and the immersion test should be 72 hours in the original product solution without abnormalities. SAILON’s custom products all provide third-party test reports, so every batch of cans is traceable.
Q: Why can’t ordinary aerosol tin can be directly used for chemical products?A: Ordinary tin cans lack targeted protective coatings, and the metal itself is prone to oxidation reactions with chemical substances. For example, when packaging chlorine-containing disinfectants, ordinary tin cans may show obvious rust within 3 days, while custom corrosion-resistant cans can be used for more than 12 months.
Q: What information do I need to provide to the manufacturer when customizing?A: At least clarify the main ingredients, concentration, and pH value of the chemical product, as well as the product’s storage environment (such as whether high-temperature transportation is required) and shelf-life requirements. This information helps the manufacturer accurately match the coating and can body process, avoiding a one-size-fits-all customization plan.
Q: Is price proportional to corrosion resistance?A: Not necessarily. Some manufacturers use the gimmick of “thick coatings” to raise prices, but the actual protective effect is average. SAILON’s approach is to accurately match according to product characteristics — for example, using economical epoxy resin coatings for weakly corrosive products, and high-cost fluorocarbon coatings only for strongly corrosive products, ensuring effect without wasting costs.
Choosing a corrosion-resistant custom aerosol tin can is essentially about “accurate matching” rather than blindly pursuing high prices. Chemical products have diverse characteristics, and the protective plan for cans should be tailored to individual needs. In the customization process, SAILON considers every detail — from adjusting coating formulas to optimizing can body structure, and multiple tests before leaving the factory — just to let every aerosol tin can steadily guard the safety of chemical products. After all, reliable packaging is never a supporting role, but an important guarantee of product quality and safety.
