METCHEM  6550  is  a  medium-duty,  bio-stable synthetic machining  and grinding coolant for mixed metals. METCHEM 6550 is compatible with aircraft aluminums,copper alloys and yellow metals.  METCHEM 6550 is a unique blend of corrosion inhibitors, surfactants and anti-wear agents. This coolant provides exceptional fine settling, rust protection and detergency to most metals. METCHEM 6550 can beused in individual sumps and central systems. METCHEM 6550 does not contain petroleumoil, chlorine or sulfur.
