Multiple Latex Dipping and Delamination Problem

Manufacturer: In one of our dipping processes, we are doing double latex dipping with the first dip in the latex followed by coagulant and a second latex dip. We are observing some technical problems of the final products. What is you comment of such dipping process?

John Woon (Senior Latex Consultant): The advantage of dipping the former into latex as the first step is that it could overcome slippage problem of the latex gel or film from the formers especially with wet coagulant (such as acetic acid), smooth/glazed formers and to a certain extent the shape of the formers.

Since it involves two latex dipping, the first latex and the second latex layers might not integrate sufficiently well due to the presence of a layer of the coagulant between them. This could therefore lead to delamination.
