Patent number: 9840579Abstract: 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.Type: GrantFiled: September 11, 2014Date of Patent: December 12, 2017Assignee: Dow Global Technologies LLCInventors: Irena Amici-Kroutilova, Paul Cookson, Daniel Hoenhener, Francois Casati

Patent number: 9840578Abstract: PIPA polyols are made in a two-step process. In the first step, a base polyether polyol and a polyisocyanate are reacted to form a mixture that contains unreacted base polyol, unreacted polyisocyanate and adducts of the base polyol and polyisocyanate. A low equivalent weight polyol is then added and reacted in a second step to form the dispersion. The process unexpectedly produces a stable dispersion of the fine PIPA particles in the base polyol, even when the base polyol contains mostly secondary hydroxyl groups. The process also permits the tuning of product viscosity by increasing or decreasing the extent of reaction in the first step.Type: GrantFiled: September 11, 2014Date of Patent: December 12, 2017Assignee: Dow Global Technologies LLCInventors: Paul Cookson, Francois Casati, Ricco Borella, Daniel Hoehener, Irena Amici-Kroutilova
