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