Abstract
The present disclosure provides coating compositions and cured products formed from the coating compositions. The cured products can be formed at high cure speeds from the coating compositions and feature low Young's modulus, high tear strength, and/or high tensile toughness. The cured products can be used as primary coatings for optical fibers. The primary coatings provide good microbending performance and are resistant to defect formation during fiber coating processing and handling operations. The coating compositions include an oligomer, an alkoxylated monofunctional acrylate monomer, and preferably, an N-vinyl amide compound.
