Preservative Low-heavy-metal Zinc Phosphate 1. Anti-corrosive properties 2. Zinc content: min 45% 3. Auxiliary coating agent
Preservative Low-heavy-metal Zinc Phosphate
1. Property:
As a white coloring pigment, it is flexible to match any top coat through color mixing as required, which can simplify the preparation process of painting and coating significantly.
With low heavy metal, good thermal stability and excellent rust prevention, zinc phosphate is nontoxic, environment-friendly, not irritative to skin and cost-effective due to little required in coating materials.
