Abstract

PURPOSE:To impart excellent gloss, transparency, antifouling quality, durability and resistance to marring and weather to furnishings, by providing a protective layer contg. a specified crosslinked fluorocopolymer on furnishings. CONSTITUTION:A copolymer mainly composed of chlorotrifluoroethylene or tetrafluoroethylene (A), a lower fluoroalkyl vinyl ether (B) (e.g. 2,2,2- trifluoroethyl vinyl ether) and a hydroxyalkyl vinyl ether (C) (e.g. hydroxybutyl vinyl ether), is prepd. A crosslinking agent (e.g. hexamethylene diisocyanate) is blended with the copolymer and the mixture is homogeneously dissolved in a solvent. The resulting paint compsn. is applied to furnishings made of wood, plastic or metal, and cured by crosslinking it at room temp. to form a protective layer, thus obtaining the desired coated furnishings.
