Abstract: In the preparation of an improved adhesive composition, an epoxy-based prepolymer is obtained by the reaction of one or more epoxy resins with amino-terminated polyethers and/or carboxyl-terminated butadiene-nitrile rubbers. In one embodiment of the invention, both a solid epoxy resin and a liquid epoxy resin, each of which is a diglycidyl ether of a polyphenol such as bisphenol A, are used. The epoxy-based prepolymer is mixed with an acrylate-terminated urethane resin (preferably, one based on a polyol having a number average molecular weight of at least about 400) and a heat-activated latent curing agent to make an adhesive composition which can be pumpable at room temperature. Curable adhesives capable of expansion to about 100% with high impact resistance after curing may be obtained by inclusion of expanding agents such as expandable microspheres.

Abstract: In the preparation of an improved adhesive composition, a first reaction product is prepared by the reaction at an elevated temperature of a) 30 to 50 wt-% of an epoxy resin, solid at room temperature, which was prepared from bisphenol A and/or bisphenol F and epichlorohydrin with an epoxide equivalent weight of 400 to 700, b) 10 to 25 wt-% of an epoxy resin, liquid at room temperature, prepared from bisphenol A and/or bisphenol F and epichlorohydrin with an epoxide equivalent weight of 150 to 220, c) 35 to 50 wt-% amino-terminated polyethylene and/or polypropylene glycols and d) a carboxyl-terminated butadiene-nitrile rubber. The first reaction product is mixed with an acrylate terminated urethane resin, glass microspheres, expandable hollow plastic microspheres and a latent curing agent to make an adhesive composition which is pumpable at room temperature and capable of expansion to about 100% with high impact resistance after curing.

Abstract: A composition useful as a sealant in the automotive industry, particularly the paint shop area, is provided which comprises a plastisol, a wax and, optionally, a rheological additive, wherein the amount of wax exceeds the amount of rheological additive on a weight-by-weight basis. The composition will self-level during its application in the automobile assembly at a wide range of temperatures such that a smooth and uniform surface possessing no major imperfections is formed upon cooling of the composition.

Abstract: Waste powder prime comprising from about 30 to about 70 weight percent epoxy resin, the balance of the waste powder prime comprising filler, pigment and/or curing agent, is advantageously employed as a replacement for epoxy resins in conventional adhesion promoter systems for polymeric plastisols. The resulting compositions are useful as adhesives and sealants in industrial manufacturing processes such as in the manufacture of automobiles.
