Aluminium dihydrogen triphosphate CAS:13939-25-8 Product introduction
Product name: Aluminium dihydrogen triphosphate
CAS: 13939-25-8
MF: AlH8O10P3
MW: 287.96
Appearance: White powder.
Aluminium dihydrogen triphosphate properties :
non-toxic, odorless, white powder, insoluble in water, soluble in nitric acid and hydrochloric acid, non- volatile white powder, non-irritating to the skin. Uses: Aluminum tripolyphosphate series is an ideal replacement product for lead, chromium and other toxic anti-rust materials. The anti-rust performance of this product is better than that of anti-rust materials such as red dan, zinc chrome yellow, etc., and the use effect is good. The pigment is widely used in all kinds of primers and paints that combine the bottom surface. It has good affinity with varnishes. It can be used in combination with various pigments and fillers, as well as with various anti-rust pigments. Anti-corrosion coating. It is suitable for solvent-based coatings such as phenolic resin, alkyd resin, epoxy resin, epoxy polyester and acrylic resin, as well as various water-depth resin coatings (such as highly adaptable water-based epoxy ester dip coating, etc.); Application and high build coatings, powder coatings, organic titanium anti-corrosion coatings, rust coatings and asphalt coatings, zinc-rich primers, fire-retardant coatings, heat-resistant coatings, etc.
