Identificação e quantificação de resinas, cargas e pigmentos em tintas látex branca

Abstract

Resins, pigments and fillers constituents in white latex paint were identified and quantified after previous treatment under both low temperature and low pressure in order to get toilet powder from emulsion samples. TG/DTA allowed, under determined conditions, to distinguish the kind of resins, fillers and pigments in commercial paints. X-ray diffractometry was used to confirm the presence of pigment in the final residue from the thermal decomposition.
