Product Description
The coatings industry is moving towards environmentally safe products with lower VOC requirements and uses of non-toxic pigments. zhongbao is an environmentally friendly Anti-Corrosive alternative to conventional lead, zinc and chromate pigments. zhongbao is a non-toxic anti-corrosive pigment based on ion-exchange technology using porous silica as a support.
zhongbao exchanges aggressive ions, such as Na+ or H+, found in coatings for calcium or magnesium ions from the silica surface to deposit on the metal substrate, forming a protective layer. With a high ion exchange rate, zhongbao may improve shelf life without adding haze to the system while reducing weight via low specific gravity. Best used for direct contact to metal substrate.
