Abstract (en)
[origin: EP0368119A1] The use of methylpolysiloxanes containing quaternary ammonium groups bonded to silicon atoms via carbon atoms, the quotient of the number of dimethylsiloxy groups and the number of quaternary ammonium groups having a value of from 0.5 to 15, as corrosion inhibitors in mainly aqueous preparations, in particular coolants, such as water- mixed cooling lubricants, in amounts of from 0.01 to 0.1% by weight, based on the total preparation in ready-for-use form.
