Abstract
The present invention relates to an aqueous, solids-containing dipping bath composition for treating reinforcing inserts for rubber products comprising the following components or consisting of these components, (A) at least one blocked MDI mixture, the MDI mixture comprising MDI oligomers of formula (I), n being a whole number from 1 to 8, and MDI monomers; (B) at least one latex; (C) at least one compound selected from the group consisting of polyacrylates, lignin derivatives and mixtures hereof; and (D) possibly at least one additive; the dipping bath composition being essentially free of epoxides, and the dipping bath composition being essentially free of resorcinol, formaldehyde and the reaction products thereof.
