The chemical main component of antistatic agent MOA3PK-70 (CAS No.: 39322-78-6) is fatty alcohol polyoxyethylene (3) ether phosphate potassium salt, also known as alcohol ether phosphate potassium salt. This product belongs to anionic phosphate ester surfactants, with a molecular structure containing hydrophilic phosphate potassium salt groups and hydrophobic fatty alcohol polyoxyethylene ether segments, giving it excellent antistatic properties as well as emulsifying and wetting capabilities.
From a chemical structure perspective, this component is a potassium salt product obtained by the addition reaction of fatty alcohol with 3 moles of ethylene oxide (EO) to form fatty alcohol polyoxyethylene (3) ether, followed by phosphation and neutralization with potassium hydroxide. The polyoxyethylene ether segment in the molecule imparts good hydrophilicity and flexibility to the product, while the phosphate potassium salt group provides strong anionic antistatic properties, enabling the formation of conductive channels on the material surface to rapidly dissipate static charges.
The product appears as a light yellow to yellow transparent liquid, with an active content of about 70%, and the remainder is solvent (usually water or alcohol solvents). Due to its anionic nature, the product maintains chemical stability over a wide pH range and has good tolerance to calcium and magnesium ions in hard water, making the application system less prone to precipitation or deactivation.
