low-heavy-metal Zinc phosphate    (7779-90-0)

     

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.

2.Usage: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.
