Abstract:
1. A resin precursor composition comprising: an isocyanate component; a first polyol having a molecular weight of between about 600 and 800 and an OH index of between about 200 and 300 mgOH/g; a second polyol having a molecular weight of between about 100 and 300 and an OH index of between about 935 and 1,200 mgOH/g; wherein the first polyol and the second polyol form a blend that has an OH index of between about 350 and 700 mgOH/g; and wherein the cured resin precursor composition has an elastic modulus of between about 350,000 and 500,000 psi and an elongation-to-failure of between about 6% and 15%.
