Physical and chemical properties

Orthorhombic crystal

The relative density is 2.31.

Water-soluble: hardly soluble in water, slightly soluble in alcohol.

Solubility: Partially hydrolyzed when left in the air for a long time. It is relatively stable to acid. Good storage stability and weather resistance.

Chemical properties

As a white pigment, the tripolyphosphate ions inside can form chelate compounds with various metal ions, and form an excellent purification film on the surface of the coated object, which has a strong inhibitory effect on the corrosion of steel and light metals.

The main purpose

It is widely used in a variety of primers and paints with a unified bottom surface. It has good affinity with varnish, can be used with various pigments and fillers, and can also be used with various anti-rust pigments, which can effectively replace red lead and zinc. Chromium yellow and other traditional toxic anti-rust pigments to prepare various high-performance anti-corrosion coatings. Suitable for phenolic resin, alkyd resin, epoxy resin, acrylic resin and other solvent-based coatings, and various water-soluble resin coatings (such as: highly adaptable water-based epoxy ester dip coating, etc.); can also be used for thick paste type Coatings, powder coatings, organic titanium anti-corrosion coatings, rusty paints and bituminous coatings, zinc-rich primers, fire-resistant coatings, heat-resistant coatings, etc.

At the same time, aluminum dihydrogen tripolyphosphate is also used in high-temperature resistant materials and is widely used in high-temperature casting industries with good results.
