WERKWIJZE VOOR DE BEREIDING VAN EEN WATERIGE, BIJ THERMISCHE NABEHANDELING TOT EEN HARS UITHARDENDE DISPERSIE EN VOORWERPEN, VERVAARDIGD ONDER TOEPASSING DAARVAN.

摘要

Aqueous dispersion thermosetting coating compositions are provided which bake to provide hard and flexible glossy coatings, the dispersion including an aqueous emulsion copolymer of ethylenic monomers including from 5-30% of non-nitrogenous hydroxy functional ethylenic materials, part of which are monomeric, and part polymeric, the ethylenic monomers being preferably copolymerized in admixture with organic mercaptan. The dispersion further includes aminoplast resin to cure the copolymer through its hydroxy functionality.
