ABSTRACT:
A corrosion protection agent for functional fluids is disclosed, comprising 5 to 80 wt. % of at least one fatty acid alkanolamide, based on saturated or unsaturated fatty acids with 10 to 20 carbon atoms, 5 to 80 wt. % of at least one alcohol with 2 to 14 carbon atoms and 5 to 80 wt. % of at least one aromatic moncarboxylic acid or an aliphatic dicarboxylic acid with 10 to 12 carbon atoms, whereby the sum of said components amounts to 100 wt. % and the wt. % is based on the weight of the corrosion protection agent, a water-miscible concentrate, containing said corrosion protection agent, for functional fluids based on water and use thereof for the production of lubricants, abrasive agents, hydraulic fluids and cooling lubricants for metal working and metal cutting.
