FIELD: varnish-and-paint industry. SUBSTANCE: invention aims at manufacturing lacquer coatings, e.g. motor car enamels, with lowered hardening temperature. Melamine-alkyd enamels contain drying accelerator based on phosphoric acids, oligomeric fluorine-containing alcohol-telomers of general formula H(CF2CF2)nCH2OH, where n=3, taken in amount 1.5-2% of the weight of enamels, after which enamels are applied onto support before hardening at 50-60 C during 35 min. EFFECT: improved complex of physicochemical characteristics, in particular regarding adhesion, impact strength of film, and complex of protective-decorative properties regarding moisture resistance, waterproofness, dust and mud retention. 1 tbl, 9 ex |
