Abstract: An adhesive article comprises a rupturable container and a moisture-curable composition. The rupturable container defines an enclosed cavity. The moisture-curable composition is disposed within the enclosed cavity. The moisture-curable composition comprises a prepolymer comprising the reaction product of an isocyanate component and an isocyanate-reactive component. The moisture-curable composition further comprises a catalyst component and an acid halide component. The adhesive article may be used in various industries and for various applications, such as for construction and remodeling of commercial, industrial, and residential buildings.

Abstract: The subject invention provides a composition and a process for forming a flexible polyurethane foam sealing device having improved compression set properties at increased temperatures. The sealing device is formed without the use of chemical blowing agents. The composition includes an isocyanate component for reaction with a resin component comprising an isocyanate-reactive component having a functionality of least four and a hydroxyl number of less than 40, a graft dispersion, and a physical blowing agent. The most preferred physical blowing agent is HFC-245 fa or 1,1,1,3,3-pentafluoropropane.

Abstract: The subject invention provides a foamed article having random cell structures formed by a process comprising the steps of providing a resin component and an isocyanate component and providing a first nucleation gas and a second nucleation gas, both under low pressure. The first and the second nucleation gases are added into at least one of the resin component and the isocyanate component. The resin component and the isocyanate component are reacted to form the foamed article having a first cell structure resulting from the addition of the first nucleation gas and a second cell structure that is different than the first cell structure resulting from the addition of the second nucleation gas. The foamed article is particularly suited for replacing metal springs in an article of furniture while still maintaining the feel and comfort of the metal springs.

Abstract: The subject invention provides a viscoelastic polyurethane foam having a density of from one to thirty pounds per cubic foot formed from a composition comprising an isocyanate component substantially free of toluene diisocyanate, an isocyanate-reactive component, and a chain extender having a backbone chain with from two to eight carbon atoms. The chain extender also has a weight-average molecular weight of less than 1,000 and is present in an amount of from 5 to 50 parts by weight based on 100 parts by weight of the composition. The viscoelastic polyurethane foam has a glass transition temperature of from 15 to 35 degrees Celsius and a tan delta peak of from 0.9 to 1.5.
