Patent number: 8455679Abstract: A prepolymer system has a monomeric isocyanate content of no greater than about 10% by weight based on 100 parts by weight of the prepolymer system. The prepolymer system comprises a diluent component and a prepolymer component different than and separate from the diluent component. The diluent component has an excess of isocyanate (NCO) functional groups, and comprises the reaction product of a monohydric isocyanate-reactive component and an excess of a first isocyanate component. The first isocyanate component comprises monomeric isocyanates reactive with the monohydric isocyanate-reactive component. The prepolymer component also has an excess of NCO functional groups, and comprises the reaction product of a polyol component and an excess of a second isocyanate component. The prepolymer system can be used to prepare foams via reaction with water. The foams have low density and have excellent adhesion and sound dampening properties for use in cavities of automobile bodies.Type: GrantFiled: December 12, 2008Date of Patent: June 4, 2013Assignee: BASF SEInventors: Thomas G.

Publication number: 20110190431Abstract: Iron contaminants are associated with a beta-dicarbonyl in an isocyanate composition that includes polymeric methylene diphenyl diisocyanate (PMDI). The association of the iron contaminant and the beta-dicarbonyl is thought to minimize a catalytic effect of the iron contaminant when the isocyanate composition is reacted with a polyol to form a polyurethane. The iron contaminant is associated with the beta-dicarbonyl in a method that includes the step of providing the isocyanate composition and the step of combining the beta-dicarbonyl and the isocyanate composition. The isocyanate composition is included in a polyurethane system and typically includes the association product of the iron contaminant and the beta-dicarbonyl.Type: ApplicationFiled: January 29, 2010Publication date: August 4, 2011Inventors: Thomas G. Savino, Sandra Bananto, Jason L. Gibson
