Aluminum Tripolyphosphate

1.Usage:Aluminum Tripolyphosphate is the ideal substitute of toxic antirust pigments containing lead or chrome. This product is superior to such antirust pigments as lead red, zinc chrome yellow and zinc phosphate in rust prevention and practicality. 
2.Properties: White powder, insoluble in water, density: 2.6-3g/cm, nontoxic, not irritative to skin, free of harmful heavy metal elements like lead or chrome and good thermal stability.  It is very cost-effective for only little amount required in production of coating materials and flexible in color mixing for its white color.  
3.Applications: This coloring pigment is able to widely substitute conventional toxic antirust pigments such as lead red and zinc chrome yellow in the production of various prime coats and combined coating materials. It can be used together with various coloring pigments, filling agents and antirust pigments in the production of high performance anti-corrosion coating materials.
