EPOXY RESINS ARE BLENDED WITH A CURING AGENT COMPRISING A MIXTURE OF METAL SALT COMPLEXES OF IMIDAZOLES AND NITROGENOUS COMPOUNDS SUCH AS UREA, DICYANDIAMIDE, MELAMINES AND THIOUREAS TO FORM COMPOSITIONS WHICH REMAIN IN THE UNCURED STATE FOR LONG PERIODS OF TIME AT ROOM TEMPERATURE, CURE CONVENIENTLY AT ELEVATED TEMPERATURES AND HAVE EXCELLENT SHEAR STRENGTH AND PEEL STRENGTH. THESE EPOXY RESIN COMPOSITIONS MAY BE USED AS COATINGS, ADHESIVES, POTTING COMPOUNDS, CASTINGS AND LAMINATES. |
