Title (EN) METHOD FOR CLEANING ARTICLES MADE OF MOLDED RESIN
(FR) PROCEDE DE LAVAGE D'ARTICLES FABRIQUES A BASE DE RESINE MOULEE
Abstract:
(EN) The prepainting cleaning of molded resin articles, particularly those made from resins containing an internal mold release agent and molded with the use of an external mold release agent, is improved by first cleaning in an aqueous alkaline solution containing an alkaline builder and surfactants, rinsing with water, and then cleaning in an aqueous acidic cleaner, preferably including surfactant and/or organic solvent.
(FR) On confère une meilleure efficacité à l'opération de lavage d'articles en résine moulée, notamment ceux fabriqués à partir de résine contenant un agent de démoulage interne et moulée à l'aide d'un agent de démoulage externe, dont la surface est ainsi lavée pour recevoir une peinture, en nettoyant d'abord l'article dans une solution alcaline aqueuse contenant un adjuvant alcalin et des gagents tensioactifs, en le rinçant à l'eau, puis le lavant dans un bain de lavage acide aqueux, contenant de préférence un agent tensioactif et/ou un solvant organique.
