Disclosed is an adhesive system and method of use thereof wherein the adhesive composition comprises a moisture curable adhesive comprised of an isocyanate terminated prepolymer and a cure accelerator having two curatives components having different cure kinetics. The cure accelerator is comprised of an isocyanate reactive compound comprising a primary, secondary or tertiary amino group, or a primary thiol group having faster curing kinetics resulting an increase in bead stability within the first minutes and a polyol selected from a diol and/or triol with slower curing kinetics allowing for sufficient open time and yet a fast strength build up. The preferred method of application of the adhesive system is via a 1K application gun.

This invention relates to polymer polyols which comprise one or more base polyols, at least one preformed stabilizer, one or more ethylenically unsaturated monomers, and, in the presence of at least one free radical polymerization catalyst, and optionally, one or more polymer control agents. The base polyol of these polymer polyols comprises one or more amine initiated polyols.

The present invention provides flexible and integral skin-containing polyurethane foams and two-component foam forming compositions for making them that comprise an aromatic polyisocyanate component, such as a methylene di(phenyl isocyanate), and a polyol component of an autocatalytic aliphatic polyether polyol and a melt modifying catalyst, such as potassium acetate, that exhibit excellent inherent flame retardant properties, passing exacting tests prescribed by the UN/ECE 118.02, Annexes 6, 7 and 8. The foam forming compositions may be all liquid and thus readily processible. Further, the two-component foam forming compositions and the polyurethane foams therefrom are halogen and melamine free and exhibit low emissions and low odor.
