Abstract: A composition of matter is provided for preparing a foamed polymer adhesive includes a reactive mixture, a free radical-producing catalyst, and a foaming agent. The reactive mixture includes methacrylate ester monomer and a thermoplastic polymer soluble therein. The polymerization reaction causing shrinkage of the reactive mixture. The foaming agent causes expansion of the reactive mixture to form a closed celled foam that offsets at least in part the shrinkage of the reactive mixture caused by the polymerization reaction. The foaming agent includes an acid-neutralizing base and a second part being an acid that is ethylenically saturated or aromatic. A substrate is bonded by the adhesive independent of an intervening primer. The adhesive can be formed at a variety of densities and prevents print through on opposing sides of the substrate. A substrate with an oxide or oil coating can be bonded without removal of the coating.

Abstract: A two part composition formulation is provided with a composition part A including a phenol novolac epoxy in combination with a bisphenol F epoxy, bisphenol A epoxy, or a combination thereof that define a base resin. A resorcinol diglycidyl ether present is present in part A in a ratio of 1.5-25:1 relative to the base resin. A part A inorganic particulate has x-y-z average linear dimension of between 500 and 6,000 microns. An activator part B includes a curative operative to cure the base resin and the resorcinol diglycidyl ether along with a part B inorganic particulate has x-y-z average linear dimension of between 500 and 6,000 microns. A coating is obtained upon mixing and cure in contact with a substrate to form a corrosion and abrasion resistant structure. A process of forming such a structure is also provided.

Abstract: A method of bonding includes providing a thermoplastic substrate having a surface with a surface energy value of less than a 48 miliJoules per meter squared. The surface is exposed to particulate formed in a combustion flame from a precursor. The particulate forms an adherent layer of metal oxide on the surface. An adhesive is applied to the adherent layer. A second substance is placed in in simultaneous contact with the adhesive to bond the thermoplastic. A laminate is provided that includes a thermoplastic substrate having a surface. An adherent layer of metal oxide is on a surface of the thermoplastic substrate. An adhesive is attached to the adherent layer. A second substance is in simultaneous contact with the adhesive.

Abstract: An adhesive composition is provided that includes a block copolymer present at greater than or equal to 30 total weight percent of the adhesive system comprising a high glass transition temperature in subunits Y and Y?, each of the subunits Y and Y? having a high glass transition temperature of from 70° C. to 130° C. with a low glass transition temperature subunit Z having a low glass transition temperature of from ?100° C. to 10° C. intermediate between said high glass transition temperature acrylate subunits to define a structure Y-Z-Y?. The triblock copolymer is dissolved in a monomer curable under free radical. A free radical initiator of a peroxide or a hydroperoxide are present in combination with a sulfonyl chloride, dihydropyridine and copper or vanadium salt. By heating the cured adhesive at or above 70° C., the adhesive is amenable to being removed, repaired, or reworked.
