Abstract
Coated optical fibers comprise a glass optical fiber and a radiation-cured coating formed from a radiation-curable liquid coating composition. The liquid coating composition comprises at least one aliphatic urethane acrylate oligomer, at least one acrylated or methacrylated compound selected from the group consisting of isobornyl acrylate, isobornyl methacrylate, alkanediol diacrylate, alkanediol dimethacrylates, alkoxylated derivatives thereof, and mixtures thereof, and a photoinitiator. In one embodiment, the compositions further include a silicone compatibility agent which reduces the coefficient of friction of the radiation-cured coating without disadvantageously effecting other physical properties of the liquid coating compositions or the cured coating, and particularly without disadvantageously effecting the optical clarity of the liquid coating compositions. In a second embodiment, the liquid coating compositions further comprise at least one silicone compatibility agent and at least one functionalized silicone compound which reduces the coefficient of friction of the radiation-cured coating while additional advantageous physical properties of the liquid coating composition …
