ControXid 1642 from oelheld U.S. Inc. 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. Moreover, ControXid 1642 effectively dissipates heat.

It is for temporary corrosion protection during hydraulic tests, for corrosion protection in coolant circuits and as a coolant for machine tool spindles.

ControXid 1642 is not caustic; it does not contain nitrites, chromates or heavy metals and no phosphates, chlorine compounds or amines.

ControXid 1642 protects ferrous metals (steel, cast iron) against corrosion and has no effect on aluminium alloys, other nonferrous metals or mineral oil-based sealing materials.
