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.
3.Specification:The technical specification is as follows in conformance to Standard Q/84XS01-2004.
