  • Physical property improvement of polyurethanes
    Patent number: 11267929
    Abstract: 100% solids polyurethanes having improved physical properties in terms of Shore hardness, tear strength, elongation at break and/or tensile strength are realized through the introduction of 100% solids hydroxyl-functional acrylics in combination with the hydroxyl-functional polyether and 100% solids isocyanate-functional compounds. When an aromatic isocyanate is used, the isocyanate-reactive component includes from 5 to 70% by weight of a hydroxyl-functional polyether having a weight average molecular weight 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 having a weight average molecular weight ranging from 180 to 6,500 g/mol, and 30 to 60% by weight of a hydroxyl-functional acrylic.
