How to Choose the High-Quality Water-Based Aerosol Cans

Water-based aerosol cans use water as the main solvent, characterized by their eco-friendliness and low toxicity. When selecting these cans, several key factors must be considered:

1. Quality of the Tinplate

The tinplate used for manufacturing the can must have high purity. If the impurity content is too high, it affects processing properties such as ductility, brittleness, and hardness, as well as corrosion resistance. Some manufacturers use low-quality, thin tinplate to reduce costs, which may have tiny sand holes leading to leaks. This should be carefully checked when choosing the tinplate.

2. Quality of Can Body Welding and Coating

One of the weakest points of a tinplate can is the weld seam. Besides strict mechanical performance requirements, the weld seam is easily corroded because the tin layer is damaged. Thus, coating is a key technology for three-piece cans. Many water-based product leaks are due to incompatibility between the coating and the contents. Additionally, unstable current or poor-quality copper wire can cause weak welding, leading to leak points.

3.Type and Density of Internal Coating

Internal coating is one of the most effective methods for preventing corrosion in water-based products (except those using DME as a propellant). However, the quality of the coating material and application process affects corrosion resistance. If there are barely visible bubbles in the coating, electrochemical reactions can occur, leading to corrosion and rusting over time, especially where the top and bottom covers contact the can body weld seam. Thus, the coating density is crucial. Common internal coatings include epoxy-phenolic, imide-epoxy, and PVC, with epoxy-phenolic being the most used. Compatibility testing is essential when choosing the coating.

4.Sealing Quality

Good sealing equipment and processes are critical for ensuring the aerosol can's sealing performance. The hook overlap amount in the seaming process is an important indicator. Poor control in this area (including manufacturing processes and testing) can result in barely detectable micro leaks at the seam.

5.Leak Testing

Aerosol products are mostly flammable and explosive. Every can must be tested with an online pressure leak detector, and deformation pressure and burst pressure must be tested as per regulations to ensure safety during production, storage, transportation, and use. Some manufacturers skip these tests to cut costs, leading to potential quality or safety hazards.

6.Sealant

The seal between the can body and the lid depends on the sealant. The quality of the sealant and the coating process is critical. Besides controlling the quality of the sealant, its swelling and dissolution properties with various solvents, especially strong solvents like DME, must undergo rigorous, long-term testing. Issues can arise if the sealant is damaged, such as through interrupted or uneven application, bubbles, or insufficient application. Given the diverse nature of aerosol contents and the inability to determine sealing performance in a short time, the quality of the sealant is ensured through long-term production experience and strict quality control by the can manufacturer.

By paying attention to these factors, you can ensure the selection of high-quality, reliable water-based aerosol cans that meet your specific needs.
