Low-heavy-metal zinc phosphate

Low-heavy-metal Superfine 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.

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.
