  • One-part hot-sprayable epoxy resin systems and methods
    Patent number: 4751129
    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.
