Abstract
Processes for enhancing the drainage of residual aqueous rinse from the external surfaces of plastic parts, such as auto fascia, are disclosed. The processes employ an aqueous solution of a zircoaluminate compound, which when applied to the surfaces of plastic parts will not rinse off during subsequent rinse stages and will remain on the plastic parts.
Claims8
A process for enhancing the drainage of residual aqueous rinse for the external surfaces of plastic parts comprising contacting said plastic parts with an effective amount of an aqueous solution of a ziroaluminate compound, for the purpose of enhancing said the drainage of residual aqueous rinse, wherein said compound remains on the surfaces of said parts during subsequent rinse stages.
