The dye must possess the necessary set of operating characteristics, exhibit resistance to the negative impact of external factors and remain effective for a long period time.

The following types of dyes are used for treating metal surfaces:

• nitro (SC, an aerosol);
• Nitrocellulose (PD);
• rubber;
• hammer;
• polymeric.

Each dye type has certain advantages and disadvantages inherent in the composition and performance characteristics allow to pinpoint the positive qualities of the coating under what conditions will bring maximum favor.

The properties of spray paint in cans, metal

Nitro composition for dyeing metal surfaces produced by manufacturers in the form of aerosol cans. This type of dye is ideal for the decoration of products of small size.
