US 2022/0134603 A1 · AQUEOUS DIPPING COMPOSITION

Abstract

The present invention relates to an aqueous dipping composition for coating a textile reinforcing material, comprising 4% to 40% by dry weight of at least one rubber latex, with the proviso that the rubber latex is no isoprene rubber latex, 0.1% to 10% by dry weight of at least one blocked isocyanate, 1% to 20% by dry weight of at least one isoprene rubber latex, and 0% to 6% by dry weight of at least one epoxy group-containing compound, wherein the amounts in % by dry weight are based on the total weight of the aqueous dipping composition. The composition is essentially free of resorcinol, resorcinol precondensates, formaldehyde and formaldehyde-releasing substances. The present invention relates to a use of such a composition, a process for coating a textile reinforcing material with this composition, a coated textile reinforcing material and a respective elastomeric article comprising the same.
