Abstract
A composition treating a metal surface, especially a metalworking fluid, includes the reaction product of at least one amine-functionalized organosilane and at least one organophosphate and/or at least one oligomer or polymer of the reaction product, wherein the molar ratio of the amino group/s of the at least one amine-functionalized and of the at least one organophosphate is 1.0:0.4 to 1.0:1.2, and wherein the at least one amine-functionalized organosilane is linked to the at least one organophosphate by at least one phosphoric acid/amine salt bond. Also described herein is method for producing such a composition, the use of the composition, and a method for treating a metal surface.
