  • Patent number: 9963588
    Abstract: An article is reinforced by applying to it a thermally curable composition of a resin mixture of 10% to 60% by weight of a diglycidyl ether of bisphenol-A, 5% to 25% by weight of an epoxy novolac, and 5% to 25% by weight of a reinforcement material comprising carbon fibers. Following application, the composition is cured. In some instances, at least a portion of the diglycidyl ether of bisphenol-A and/or the epoxy phenyl novolac resin may be adducted with an elastomer.

  • Patent number: 6861464
    Abstract: A two component, curable hot melt adhesive system includes a first hot melt adhesive formulation which has a softening temperature greater than room temperature and which includes a first component of a curable adhesive therein. The system includes a second hot melt adhesive formulation which has a softening temperature which is greater than room temperature and which includes a second component of a curable adhesive therein. The second component is reactive with the first component to provide a cured adhesive bond. In use, the two formulations are heated to a temperature above their softening temperature and are contacted so as to cause mixing. The mixture cools to provide a thermoplastic bond which subsequently cures to provide a permanent adhesive bond. While the first and the second component individually perform as hot melt adhesives, combining the first and the second gives enhanced adhesive performance in extended temperature ranges.

  • Patent number: 6210517
    Abstract: A radiation curable precursor coating composition for the preparation of a non-blocking, heat activatable adhesive includes a curable acrylic material, a curable elastomeric material, and a hydrocarbon tackifier material having a softening temperature ranging from approximately 50° C. to approximately 200° C., wherein when the acrylic material and the elastomeric material are cured, the coating composition is non-blocking at room temperature, but when the coating composition is heated to a temperature above both the softening temperature of the hydrocarbon tackifier and the Tg of the coating composition, the coating composition becomes adhesive.

  • Patent number: 5132032
    Abstract: A lubricant composition for use in metal-forming operations is compatible with aqueous-based paint baths and includes an oil having dissolved therein an ester derived from a C.sub.1 -C.sub.5 alcohol and a C.sub.10 -C.sub.25 acid. The ester is typically a methyl or ethyl ester and is present in weight concentrations of up to 30%. One specific pre-lubricant composition includes methyl oleate as the ester. The composition may further include corrosion inhibitors, antioxidants, lubricity builders and the like.
