Films were cured and aged at 225 °C vs. the SC-3 secondary coating. Results are listed in Figure 9. The incorporation of the heat-resistant silicone urethane acrylate provided formulas that even after 24 hours had nearly 90% weight retention. Summary A number of acrylate-based secondary optical fiber coatings have been evaluated for property changes upon exposure to elevated temperatures. Of the materials tested, a coating consisting of specific types of urethane acrylate oligomers and hexanediol diacrylate diluent was the most resistant to weight loss, color change and increases in crosslink density upon exposure to temperatures from 125 to 225 °C. In addition, monomeric and oligomeric materials were also cured in neat form and aged at elevated temperatures. Oligomeric materials have been found that possess enhanced thermal resistance over that of the urethane and HDODA based coating. These results are part of the ongoing development of fast-curing technologies for higher temperature optical fiber applications. Bring on all your bright ideas.
