As wetting agent with defoaming ability, Hordaphos MDAH is mainly used in alkaline cleaning agents and in surface treatment for the printing and coating industry. Furthermore, it is used as a dispersing agent in pigment pastes. In metal pigment pastes the ester acts as a corrosion inhibitor. Moreover, Hordaphos MDAH is used in extraction and flotation agents.
