Product Description

Aluminum tripolyphosphate in the coating of chemical rust and isolation rust prevention


1. Usage:

Aluminum tripolyphosphate can dissociate tripolyphosphate ions in the coating, and it contains 5 active oxygen bonds that can be cross-chelated with metal cations. It has a strong ability to capture metal ions and can effectively block the formation of metal ions. Inorganic polymer complexes, passivate the metal surface, and play a chemical anti-rust effect. Then it slowly decomposes into a dense orthophosphoric acid film, which isolates moisture, oxygen, etc. from contact with the metal surface, and has the effect of isolating and preventing rust. Therefore, it has the dual effects of chemical rust prevention and isolation and rust prevention.


2. Applications:

It is widely used in various primers and paints with a bottom surface. It has good affinity with varnishes and can be used in combination with various pigment ingredients. It can effectively replace traditional toxic anti-rust pigments such as red lead and zinc chrome yellow to prepare a variety of High-performance anti-corrosion coatings.

Suitable for solvent-based coatings such as phenolic resin, alkyd resin, epoxy resin and acrylic resin, as well as various water-soluble resin coatings (such as: highly adaptable water-based epoxy ester dip coating, etc.); it can also be used for thick Paste coatings, powder coatings, organic titanium anti-corrosion coatings, rusty paints and bitumen varnishes, zinc-rich primers, fire-resistant coatings, heat-resistant coatings, etc.
