Antistatic agent MOA3PK-40 (CAS: 39322-78-6) is an anionic special surfactant, whose active ingredient is fatty alcohol polyoxyethylene ether phosphate ester potassium salt (also known as alcohol ether phosphate potassium salt, polyoxyethylene fatty alcohol ether phosphate potassium salt), supplied in aqueous solution. This product is a potassium salt type obtained by phosphorylating fatty alcohol polyoxyethylene ether followed by neutralization with potassium hydroxide, combining the anionic characteristics of phosphate groups with the hydrophilicity of polyoxyethylene chains.
From a chemical structure perspective, the molecule contains hydrophilic phosphate potassium salt groups and polyoxyethylene ether chains, as well as hydrophobic long-chain fatty alcohol groups. This unique amphiphilic structure endows it with excellent surface activity, enabling the formation of a continuous conductive molecular layer within polymer materials, achieving efficient and long-lasting static dissipation functionality.
