Abstract

1408165 Polyurethane lacquer WITCO CHEMICAL CORP 29 Nov 1972 [30 Nov 1971] 55218/72 Heading C3R A one-component polyurethane lacquer solution comprises a prepolymer of a linear OH- terminated polyether or polyester and toluene diisocyanate which has been chain extended with sufficient menthane and/or isophorone diamine to react completely with 80 to 96% of the available NCO groups, and also for polyester derived prepolymers (but only optionally for polyether-derived prepolymers) sufficient C 2-22 alkyl and/or cycloalkyl monoamines to react completely with up to 10% of the available NCO groups, such chain extended prepolymer being dissolved in a solvent mixture comprising at least 5 vol. per cent of a C 1-5 alkanol and such other inert organic solvents as may be required to produce a "balanced solution", i.e. wherein all the components remain in solution after all the ingredients have reacted. Antioxidants, e.g. dibutylated phenols, and U.V. absorbers, e.g. benzotriazoles, may be included. In specific prepolymers are used from poly-(1,2-oxypropylene) glycol, poly-(oxytetramethylene) glycol and polyesters of adipic acid with ethylene, tetramethylene, hexamethylene or a mixture of ethylene and propylene glycols; the monoamines used are mono- and di-butylamines, npropylamine, diethylamine and n-octadecylamine, and the solvent combinations are (by volume), MEU/ethanol/DMF, 80/15/5; toluene/ isopropanol/DMF, 65/20/15 and 70/25/5; MEK/ ethanol, 80/20; toluene/n-propanol/DMF, 70/ 20/10; and MFK/acetone/isopropanol/DMF, 40/40/10/10.
