  • Publication number: 20070034432
    Abstract: A solid thermally expansible material is provided. The material includes a solid epoxy resin that is substantially free of liquid epoxy resin and semi-solid epoxy resin. The material also includes an impact modifier, a curing agent and a heat-activated foaming agent. The impact modifier includes rubber in one embodiment and is substantially free of rubber in another embodiment. Following heat activation, the material expands and can adhere to a substrate. A cured expanded reinforcement material is also provided, as is a method of reinforcing a substrate.

  • Publication number: 20040253453
    Abstract: A method for installing a constrained layer damper on a product of manufacture is disclosed. The method includes applying a layer of first polymeric material to a substrate of the product, wherein the first polymeric material is visco-elastic when solidified. Then, a second layer of polymeric material, which is stiff when solidified, is applied to the first polymeric material such that said first polymeric material is constrained between the second polymeric material and the substrate of the product. At least one of the layers of polymeric materials is dispensed in fluid form during the manufacture of the product from a bulk source of fluid material. The polymeric materials are chosen such that they do not require the application of heat above room temperature to solidify.

  • Publication number: 20030070741
    Abstract: A polyurethane adhesive which is useful in bonding porous and non-porous surfaces is provided. The adhesive is especially useful in bonding windshield glass into automotive frames under a variety of environmental conditions, particularly in after market windshield replacement applications. The polyurethane includes at least one urethane prepolymer which is based on at least one thermoplastic polyol. In one embodiment, the urethane prepolymer may be formed from one or more polyisocyanates, one or more polyetherpolyols and one or more thermoplastic polyesterpolyols, wherein the prepolymer has a free isocyanate content of from about 0.6 to about 3.5 % by weight, based on the weight of the polyurethane. In another embodiment, a one-part adhesive composition is provided which includes an isocyanate-functional and thermoplastic polyurethane prepolymer having a free isocyanate content of from about 0.6 to about 3.

  • Patent number: 6511752
    Abstract: A method is provided for adhering a polyurethane-based sealant or adhesive to a substrate. The method comprises: i) applying an aqueous primer solution onto a substrate, the primer solution comprising water, an aminotitanate compound, and preferably an epoxysilane compound having at least one epoxy group and at least two alkoxy groups; ii) applying a polyurethane adhesive or sealant to the primer-treated substrate; and iii) forming a reaction product of the primer and the polyurethane. Also provided are a substrate having a layer of a polyurethane adhesive or sealant, and a stabilized aqueous primer solution containing an epoxysilane compound and an aminotitanate compound.

  • Patent number: 6068885
    Abstract: 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.

  • Patent number: 5157079
    Abstract: The invention is directed to a process for preparing a sealant and adhesive useful, e.g., in double glazing systems. The sealant comprises 20-80 weight percent epoxidized natural rubber, 5-30 weight percent of at least one further epoxy compound, and, as a crosslinking agent, a polyamine or polymercaptan carrying trialkoxysilyl groups. The crosslinking agent is incorporated into the epoxidized natural rubber in one step.
