Thixotropic polyol compositions containing dispersed urethane-modified polyisocyanurates

Thixotropic polyol dispersions are described. The dispersions contain a dispersed phase of polyurethane-isocyanurate particles. They can be made by reacting a low equivalent weight polyol with a polyisocyanate in the presence of an isocyanate trimerization catalyst while dispersed in a base polyol....

Zusammenfassung:Thixotropic polyol dispersions are described. The dispersions contain a dispersed phase of polyurethane-isocyanurate particles. They can be made by reacting a low equivalent weight polyol with a polyisocyanate in the presence of an isocyanate trimerization catalyst while dispersed in a base polyol. These polyol dispersions are useful as the resin component of curable systems such as formulated coatings, sealants or adhesives.
