Aluminum tripolyphosphate is a new generation of pollution-free white antirust pigment. It is white powder in appearance, insoluble in water, with a density of 2-3g/cm3, non-toxic, non irritating to skin, and does not contain lead, chromium and other harmful heavy metals; Good thermal stability. Triphosphate ion P3O105 - can have a stronger chelating force with various metal ions, form an excellent passive film on the surface of the coating, and has a strong inhibition effect on the corrosion of steel and light metals. The color of the coating can be freely adjusted. Aluminum tripolyphosphate is an ideal substitute for lead and chromium series toxic antirust materials. Since the product was put on the market in 1993, the actual application and test results of more than 100 influential paint plants (institutes) in China show that the product has better antirust performance than red lead, zinc Chrome Yellow and other antirust materials, with good use effect.

Aluminum tripolyphosphate is widely used in various primers and bottom surface integrated coatings. It has good affinity with varnish, can be used with various pigments, fillers, and also can be used with various antirust pigments to prepare various high-performance anti-corrosion coatings. It is applicable to solvent based coatings such as phenolic Resin, alkyd resin, epoxy resin, epoxy polyester and acrylic resin, as well as various water-soluble resin coatings (such as highly adaptable water-based epoxy ester dip coating); It can also be used in thick paste coating, powder coating, organic titanium anti-corrosion coating, rust coating and asphalt paint, zinc rich primer, fire retardant coating, heat resistant coating, etc.
