Patent number: 5962093Abstract: A laminate structure comprises one or more layers of an organic polymer and one or more layers of a hydroxy-functionalized polyetheramine, wherein the hydroxy-functionalized polyetheramine layer is adhered directly to a contiguous organic polymer layer without an adhesive layer therebetween. The hydroxy-functionalized polyetheramine is prepared by reacting (1) a difunctional amine with (2) a diglycidyl ether or a diepoxy-functionalized poly(alkylene oxide) under conditions sufficient to cause the amine moieties to react with the epoxy moieties to form a polymer backbone having amine linkages, ether linkages and pendant hydroxyl moieties and then treating the reaction product with a monofunctional nucleophile which is not a primary or secondary amine.Type: GrantFiled: October 22, 1997Date of Patent: October 5, 1999Assignee: The Dow Chemical CompanyInventors: Jerry E. White, Joe T. Sanford, Terry W. Glass

Patent number: 5962602Abstract: An epoxy sealer/healer formulation for sealing and strengthening cracked concrete comprising an epoxy resin, an amine and a dialkylene triamine-alkylene oxide adduct, where the formulation provides a modulus and/or compressive strength at least that of uncracked concrete and effective for penetrating a concrete crack at a rate of at least 10 mm/min for a crack 0.5 mm wide when applied by gravity feed. The epoxy sealer/healer preferably has a viscosity of less than 100 centipoise and a tack-free time of less than 12 hours. The epoxy sealer/healer is advantageous in being able to bond to moist concrete surfaces. A method of using the epoxy sealer/healer for sealing and restoring the strength of cracked concrete is also set forth.Type: GrantFiled: February 29, 1996Date of Patent: October 5, 1999Assignee: Sika Corporation USAInventors: Stuart J. Hartman, Michael C. Coddington, David C. Elmendorf, Norman Blank
