摘要: A process and composition is described for the inclusion of polyether polyols in concentrations greater than 10% loading on the B-side formulation with a catalyst package less than 1% loading on the B-side formulation. In one specific example, the use of glycerin as a fluorine ion scavenger is utilized to improve performance of the polyurethane systems through a twelve-month shelf life.
