HJ Super Zinc Phosphate

CHEMICAL DESCRIPTION:
Calcium iron modified orthophosphates

PRODUCT INTRODUCTION:
The SUPER ZINC PHOSPHATE is a new generation modified orthophosphates pigments designed to be more active than standard Zinc Phosphate for the application of anti-corrosion paints & coating Industry.  
This products is based on a unique synergy between different ion and phosphating mechanism. It was showed the dissolution and hydrolysis was improved when the phosphating accurred on the surface of metal.
The products was suitable for a variety of resin systems like alkyds,acrylics and epoxies. Solvent-borne, water-based and for every area of application. The "flashrust" phenomenon in the water-borne paint was conquered. With a low tinting strength, there is no effect to the color of the anti-rust primer for truck, ship, container and other steel structure.
