Lanphos PET22
Product Category: Anionics
Polyaryl Ethoxy Phosphate Ester - Triethanolamine Salt
Lanphos PET22 is a phosphate ester manufactured using phosphorous pentoxide to give a product that contains both mono and di-esters. The main advantage of a phosphate ester over a conventional anionic is it’s excellent stability in high concentration of acid, alkali and electrolyte.
This product offers good wetting and dispersion properties for pigments and agrochemicals when used alone and in combination with nonionic surfactants.
