Abstract: COPOLYMERS OF 25 TO 60% BY WEIGHT OF STYRENE OR ITS DERIVATIVES, 30 TO 65% OF (METH) ACRYLIC ESTERS (EXCEPTED (METHACRYLIC ACID MTHYL ESTER) WHICH MAY BE USED IN AMOUNTS UP TO 24% BY WEIGHT) AND 3 TO 15% BY WEIGHT OF UNSATURATED COPOLYMERIZABLE CARBOXYLIC ACIDS ARE HOMEGENEOUSLY MIXED WITH TRIGLYCIDYL ISOCYANURATE AND OPTIONALLY WITH PIGMENTS AND LEVELLING AGENTS. THE MIXTURE IS APPLIED BY ELECTTROSTATIC POWDER-SPRAYING PROCESS TO METALLIC SURFACES AND CURED AT TEMPERATURES OF ABOUT 130 TO 220* C. THE BACKED FILMS OF THE MIXTURES SHOW OUTSTANDIING BOND STRENGTH AND HARDNESS COUPLED WITH ELASTICITY, HIGH GLOSS AND WEATHER RESISTNACE.
