ControXid 1642 is a ready-to-use rust protection fluid for coolant circuits based on synthetic, water-soluble corrosion inhibitors. It is low-foam and affords reliable protection against corrosion as well as high resistance to fungal and bacterial contamination. 

ControXid 1642 can be used for temporary corrosion protection during hydraulic tests, corrosion protection in coolant circuits and as a coolant for machine tool spindles. It is not caustic, does not contain nitrites, chromates, heavy metals, phosphates, chlorine compounds or amines. It protects ferrous metals (steel, cast iron) against corrosion and has no effect on aluminium alloys, other nonferrous metals or mineral oil-based sealing materials.
