The Basic Requirements for The Use of Internal Coatings for Aluminum Aerosol Cans

Aluminum is a very lively metal that can prevent further oxidation due to the formation of a thin, solid alumina film on its surface, resulting that aluminum has corrosion resistance in atmospheric, water and partially corrosive media. On the other hand aluminum is amphoteric metal, can be acid corrosion, but also can be alkali corrosion, so it usually requires paint protection.

There are the basic requirements when it is used of coating aluminum aerosol cans:

1. Meet the requirements of the certain pressure under a variety of content (including propellant) anti-corrosion;

2. Have good processing performance, to meet the necking, curling and other processing requirements ;

3. Does not affect the quality and performance of the contents.
