Ruspert: Environmental-friendly high corrosion-resistant surface treatment technology (corresponding to chromium-free treatment)

Ruspert treatment is a highly corrosion-resistant surface treatment technology consisting of zinc metal layer, special skin-forming layer and surface antirust coating. The chemical reaction and bridging effect of each layer are closely combined. This is not a common surface treatment consisting of a single skin film, but a surface treatment which exerts comprehensive corrosion resistance under the complementary action of three skin films.

Characteristics: high corrosion resistance; multicolor; low temperature treatment;
