 powder coatings

The disadvantages are:

(1) The price is more expensive;

(2) Poor corrosion resistance in coastal and acidic environments;

(3) not easy to level;

The advantages of cathode electrophoretic paint are:

(1) The film is uniform and consistent;

(2) Complete coverage;

(3) Good corrosion resistance.

The coating system with excellent comprehensive performance can be obtained by using the advantages of the two coatings. The combination of these two coatings has been used in mass production in various industries in China.

Advantages of cathodic electrophoretic paint/acrylic powder coating system:

(1) Good corrosion resistance, salt spray resistance test up to 600h according to elevator industry standards;
