Abstract

<IMAGE> The water additives contain as active substance organic phosphates having the general formula (I) and zinc phosphate. In the general formula (I), R1 is hydrogen or a cyclohexyl group and R2 is a cyclohexyl group, and n has a value comprised between 0.5 and 3. Said water additives are prepared by transformation of 5-85% of phosphoric acid with cyclohexyl amine or dicyclohexyl amine and addition to the mixture before, during or after the transformation of at the most 10% of zinc phosphate with respect to the organic phosphate or of a zinc compound forming zinc phosphate with the phosphoric acid. Said corrosion inhibiting water additive may be used in cold water- and hot water- cooling circuits in order to reduce the corrosion speed.
