Abstract (en)
[origin: WO9808886A1] The present invention relates to a polyurethane-isocyanurate casting system including an isocyanate component or isocyanate terminated prepolymer and a hardener. The hardener includes a polyol component, at least one trimerization catalyst, and, optionally, a poly(oxyalkylene) polyamine. The isocyanate component and hardener are blended at a volumetric ratio of between 2.5:1 and 1:1. The blend of component a and component b has an isocyanate index of from about 1.5 to about 4.0. The present invention further relates to a process employing the casting system and articles resulting from the casting system having a high head deflection temperature.
