Among various extreme pressure (EP) agents, chlorinated paraffins (CPs) have been the most popular EP additive in metalworking fluids (MWFs) due to the numerous advantages including cost effectiveness, wide activation temperature, versatility in applications, easy formulation and stablility in water. But CPs have health and hazard issues. Thus, MWF manufacturers are seeking CP alternatives. Along this line, the present report describes new organic-inorganic hybrid systems as new EP and corrosion inhibitor technology for MWF application.
