Abstract: A one-part composition for application to a substrate, e.g., automotive metal body panels, to provide reinforcement thereto is a thixotropic admixture containing as essential components (a) a heat curable epoxy resin system including the reaction product in the presence of a catalyst of at least one epoxy resin with a carboxy terminated elastomer, (b) dicyandiamide, and (c) a plurality of inorganic particulate filler materials, at least one of which is capable of imparting thixotropic properties to the composition. The method of reinforcing the substrate involves spraying the one-part epoxy resin containing composition onto at least a portion thereof in a heated condition and thereafter curing the composition at a temperature higher than the spraying temperature. Resulting reinforced substrates have tenaciously adhered thereto on at least a portion of one surface thereof a thermoset layer formed by the hot spraying and then curing thereon of the thixotropic composition.

Abstract: A hot melt adhesive especially suitable for adhering polyesters to polyolefins composed on a weight percent basis of about 35 to 45 percent of a copolymer of ethylene and vinyl acetate and about 5 to 15 percent by weight of a copolymer of ethylene-ethyl acrylate, about 35 to 45 percent of a resin modifier and about 5 to 10 percent of parrafin-rich processing oil and optionally 0 to 5 percent of microcrystalline wax.

Abstract: A hot melt adhesive composition suitable for adhering polyester and polyvinyl fluoride compositions is prepared by making a blend of about 9 to 30 percent of a copolymer of ethylene and ethyl acrylate or methacrylate, about 40 to 45 percent of a copolyester of a terephthalate of ethylene and neopentyl glycol and about 50 to 55 percent of a terpolyester obtained by condensing ethylene glycol with a mixture of terephthalic acid, isophthalic acid and azelaic acid.
