摘要：100% solids polyurethanes having improved physical properties in terms ofShore hardness, tear strength, elongation at break and/or tensile strength are realizedthrough the introduction of 100% solids hydroxyl-functional acrylics in combination withthe hydroxyl-functional polyether and 100% solids isocyanate-functional compounds.When an aromatic isocyanate is used, the isocyanate-reactive component includes from 5to 70% by weight of a hydroxyl-functional polyether having a weight average molecularweight ranging from 180 to 6,500 g/mol, and 30 to 95% by weight of a hydroxyl-functional acrylic. When an aliphatic isocyanate is used, the isocyanate-reactive
component includes from 40 to 70% by weight of a hydroxyl-functional polyether havinga weight average molecular weight ranging from 180 to 6,500 g/mol, and 30 to 60% byweight of a hydroxyl-functional acrylic.
