Abstract
Fiber coatings with low Young's modulus and high tear strength are realized with coating compositions that include an oligomeric material formed from an isocyanate, a hydroxy acrylate compound and a polyol. The oligomeric material includes a polyether urethane acrylate and a di-adduct compound, where the di-adduct compound is present in an amount of at least 2.35 wt %. The reaction mixture used to form the oligomeric material may include a molar ratio of isocyanate:hydroxy acrylate:polyol of n:m:p, where n may be greater than 3.0, m may be between n−1 and 2n−4, and p may be 2. Young's modulus and tear strength of coatings made from the compositions increase with increasing n. Coatings formed from the present oligomers feature high tear strength for a given Young's modulus.
