REACTIVE RINSE AID FOR PROCESSING THERMOPLASTIC OLEFINS

摘要

A method of enhancing the drainage of residual aqueous rinse from the external surfaces of thermoplastic olefin plastic parts is disclosed. The method employs an aqueous solution of tannic acid compound, which when applied to the surface of thermoplastic olefin plastic parts will not rinse off during subsequent rinse stages and will remain on the thermoplastic olefin plastic parts.
