UNA COMPOSIZIONE DI RIVESTIMENTO INDURIBILE SOPRA I 50 GRADI C CONTENENTE UNA RESINA EPOSSIDICA IDROLIZZATA

Coating compositions curable at temperatures above 50oC. Properties such as solvent resistance are improved by hydrolyzing at least a portion of the epoxy groups present in the epoxy resin. The compositions contain (1) a hydrolyzed epoxy resin such as the polyglycidyl ether of either a polyhydric ar...

Zusammenfassung:	Coating compositions curable at temperatures above 50oC. Properties such as solvent resistance are improved by hydrolyzing at least a portion of the epoxy groups present in the epoxy resin. The compositions contain (1) a hydrolyzed epoxy resin such as the polyglycidyl ether of either a polyhydric aromatic or polyhydric aliphatic compound; (2) a curing amount of a curing agent selected from (a) triazine-aldehydes, (b) urea-aldehydes, (c) compounds having an average of more than one NCO or NCS group per molecule, or (d) mixtures thereof; and (3) a sufficient quantity but less than 55 percent by weight of a suitable solvent system so as to provide a suitable application viscosity.
