Abstract: A METHOD OF APPLYING CONTINUOUS COATINGS COMPRISING POLY(VINYLIDENE FLUORIDE) WITHOUT BAKING AT HIGH TEMPERATURES COMPRISES APPLYING ON A SUBSTRATE A THIN LAYER OF A COMPOSITION COMPRISING POLY(VINYLIDENE FLUORIDE) AND CERTAIN ORGANIC LIQUIDS, THE LIQUIDS USABLE BEING THOSE HAVING A BOILING POINT BETWEEN ABOUT 125 AND 250*C. IN WHICH POLY(VINYLIDENE FLUORIDE) FORMS A SUBSTANTIALLY CLEAR SOLUTION IN CONCENTRATIONS OF AT LEAST 10 PERCENT BY WEIGHT. THE METHOD CAN BE USED TO "TOUCH-UP" OR REPAIR BAKED POLY(VINYLIDENE FLUORIDE) COATINGS, OR FOR THE APPLICATION OF CONTINUOUS PROTECTIVE COATINGS ON A SUBSTRATE.
