Abstract: A heat-curable structural adhesive includes a non-rubber-modified epoxy resin, a reaction product of a carboxyl- or amine-terminated butadiene polymer or copolymer and a bisphenol F-based epoxy resin, a elastomeric toughener containing capped isocyanate groups, one or more epoxy curing agents a moisture scavenger and a heat activatable catalyst comprising a mixture of a solid or liquid tertiary amine compound that has a boiling temperature of at least 130° C. and a novolac resin. The structural adhesive develops excellent bonding properties when cured at moderate temperatures, especially from 120 to 170° C., and in addition performs very well in environmental aging stress testing. The adhesive is particularly good for bonding aluminum to another metal, or bonding aluminum to aluminum.

Abstract: The present invention provides all liquid, two-component foam forming compositions for forming fire-resistant rigid polyurethane foams comprising a chlorine-free liquid flame retardant (FR) additive. The compositions comprise a polyisocyanate component and, as a separate component, a polyol component of a blend of one or more high hydroxyl functional aromatic polyester polyols and one or more low hydroxyl functional aromatic polyester polyols, a novolac polyether polyol, a trimerization catalysts, a liquid FR additive, preferably, one FR additive, more preferably, a halogen free FR additive, and water, or water and a physical blowing agent as a blowing agent. The low hydroxyl functional aromatic polyester polyols enable the provision of readily processible, all liquid polyol components having a low viscosity as well as ASTM E84A Class A rated rigid polyurethane foams.

Abstract: The present disclosure provides for a metal chelated polyol liquid and/or a metal chelated polyether polyol liquid that can be used in an isocyanate-reactive composition and a reaction mixture for forming a polyurethane polymer. The metal chelated polyester polyol liquid is a reaction product of a chelating polyester polyol having a chelating moiety and a metal compound having a metal ion. The metal chelated polyether polyol liquid is a reaction product of a chelating polyether polyol having a chelating moiety and a metal compound having a metal ion. The chelating moiety of the chelating polyester polyol or the chelating polyether polyol chelates the metal ion to form the metal chelated polyester polyol liquid or the metal chelated polyether polyol liquid, respectively, having a mole ratio of the metal ion to the chelating moiety of 0.05:1 to 2:1.
