How to use the Protective film for painted metal

- Mar 13, 2019-

In order to make the Protective film for painted metal play its due function, firstly, the protective film must be completely non-porous; secondly, the protective film is stable in the medium; in addition, the protective film and the main metal orange are abandoned; protective film Has a thermal expansion coefficient close to that of the host metal

 

For example, aluminum and iron can form a complete oxide film in high-temperature air. The oxide film has a protective effect on the cage condition, but the iron oxide film does not have a strong adhesion to the metal orange, so it does not protect. Another example is the alkali metal and alkaline earth metal. Because the formed oxide protective film is incomplete, it has a protective effect against gas rot.

 

The paint metal protective film produced by the high-efficiency material can cover the metal surface with a layer of material, which can effectively prevent the outside world, such as long-term climate, or raindrops, or human damage, and protect it from loss.

 

Many people have suggested that the painted metal protective film can be wiped with alcohol. The problem is obvious. Alcohol is more or less corrosive. For the protective film, no matter how good the protective film is, it is still It is relatively fragile, so if it is dirty or a little flower, it is best to wipe it with water and a cloth to prevent the painted metal protective film from being corroded.
