Amine Phosphate Antiwear Additive
Amine phosphates are ashless antiwear additives formed by the neutralization of phosphoric or phosphorous acid with fatty amines, delivering effective wear protection without contributing zinc or other metals to the formulation. They are particularly valued in zinc-free hydraulic fluids, environmentally acceptable lubricants (EAL), and applications where ZDDP is restricted. Amine phosphates also provide rust inhibition and mild acid neutralization, making them multifunctional components in hydraulic and circulating oil formulations.
