摘要: Disclosed is a polyol/polyisocyanate adhesive system having an isocyanate component and catalyzed which form heat-cured composition when admixed heated above threshold temperature. The has hydroxyl-functional with catalyst combination of heat-activatable amine or amine-like activated at temperatures the temperature, activatable complexed metal comprising reaction product tin bismuth catalysts, mixture thereof, molar excess mercapto compound complexing agent. effective to maintain processibility ambient while promoting rapid cure
