Coating composition of epoxy resins,polyester resins,and vinyl monomers
Abstract
Abstract AN IMPROVED LIQUID STABLE RESINOUS COATING COMPOSITION POLYMERIZED BY AN EPOXY CONVERTER TO A SOLID DURABLE COATING HAVING CONTROLLED FLEXIBILITY IS PROVIDED. THE COMPOSITION COMPRISES LIQUID EPOXY RESIN CURABLE AT AMBIENT TEMPERATURE WITH A CONVERTER SUCH AS AN AMINE AND A SPECIFIED VOLUME CONCENTRATION OF A LIQUID UNSATURATED POLYESTER AT LEAST ESSENTIALLY FREE OF TRIGLYCERIDE OIL AND FATTY ACID AND COMPRISING THE REACTION PRODUCT OF POLYBASIC ACID AND POLYHYDRIC ALCOHOL, AT LEAST ONE OF THE ACID AND ALCOHOL BEING UNSATURATED, IN A CONCENTRATION SUFFICIENT TO INCREASE THE FLEXIBILITY OF THE COMPOSITION, AND A PROMOTER FOR THE POLYESTER. COMPOSITION IS, IN PART, CHARACTERIZED BY BEING FREE OF A CATALYST FOR THE POLYESTER AND AT LEAST ESSENTIALLY FREE OF VOLATILE SOLVENT. THE COMPOSITION IS CAPABLE OF BEING SPREAD AS A COATING ON A SURFACE AND CURED AT AMBIENT TEMPERATURE TO A DURABLE SOLID SURFACE HAVING CONTROLLED FLEXIBILITY BY ADDING THE EPOXY CONVERTER TO THE LIQUID COMPOSITION BEFORE COATING. PRIOR TO SUCH ADDITION THE COMPOSITION CAN BE MAINTAINED OVER A CONSIDERABLE PERIOD OF TIME WITHOUT THICKENING. THE INVENTION ALSO INCLUDES A METHOD OF COATING UTILIZING THE COMPOSITION.
