The polyisocyanate particles also can be protected by a layer formed by chemically reacting said polyisocyanate particles with isocyanate reactive compounds to form a protective surface layer around said polyisocyanate particles.Type: GrantFiled: May 13, 2003Date of Patent: June 26, 2007Assignee: Bostik-Findley LimitedInventors: Jeremy Bell, Andrew Crabtree

Patent number: 7226523Abstract: 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.Type: GrantFiled: May 15, 2002Date of Patent: June 5, 2007Assignee: Sika Technology AGInventors: Steven A. Rosenberg, Hong Yao, Thomas Bove, Adrian Van Maurik, Hans Peter Tschan, Norman Blank

Patent number: 7218007Abstract: An electronic structure includes an electronic device coupled to a substrate by conductive bumps and ball limiting metallurgy (BLM). Underfill material having filler particles is disposed in a space between the electronic device and the substrate. A weight percentage of the filler particles is at least about 60%. A particle size of at least 90 wt % of the filler particles is less than about 2 ?m and/or the filler particles are coated by an organic coupling agent. Once the underfill material is fully cured, its coefficient of thermal expansion is no more than 30 PPM/° C., and its glass transition temperature is at least 100° C., and its adhesion to a passivation layer of the electronic device, to the substrate and to the electronic device at its edges is such that the electronic structure passes standardized reliability tests without delamination of the ball limiting metallurgy.Type: GrantFiled: September 28, 2004Date of Patent: May 15, 2007Assignee: Intel CorporationInventors: Song-Hua Shi, Tian-An Chen, Jason Zhang, Katrina Certeza
