Covestro DeSolite® DS-2042 Secondary Optical Fiber Coating, UV Cure (10 kg)
Covestro DeSolite® DS-2042 Secondary Optical Fiber Coating, UV Cure (10 kg)
Part Number: COV-DS-2042-10KG
The Covestro DeSolite® DS-2042 is a UV-curable secondary coating material designed to enhance the mechanical durability and long-term performance of optical fibers used in telecommunications networks. Developed for high-speed manufacturing environments, DS-2042 combines excellent processing characteristics with reliable protection against microbending-related signal loss.
Its balanced formulation allows seamless integration into both wet-on-wet and wet-on-dry coating processes, giving fiber manufacturers greater flexibility in production line configuration. The coating also delivers strong adhesion properties that help maintain coating integrity in ribbon fiber and loose-tube cable designs while supporting long-term environmental and aging performance.
DS-2042 is engineered to withstand the demanding conditions encountered during fiber production and deployment. Excellent cavitation resistance and strong mechanical properties contribute to stable manufacturing performance, while support for high draw speeds helps improve productivity without compromising fiber quality.
