Desolite® 3471-3-14 Single Coat Primary Optical Fiber Coating, UV Cure (10 kg)
Covestro DeSolite® 3471-3-14 Single-Coat Primary Optical Fiber Coating, UV Cure (10 kg)
Part Number: COV-3471-3-14-10KG
The Covestro DeSolite® 3471-3-14 is a UV-curable single-layer optical fiber coating developed for applications requiring strong mechanical protection, excellent adhesion, and long-term environmental stability. By combining the benefits of a primary coating system into a single material, this coating helps simplify fiber processing while delivering dependable optical and mechanical performance.
Featuring a high-modulus formulation, DeSolite® 3471-3-14 provides enhanced resistance to mechanical stress and handling damage while maintaining strong adhesion to the fiber surface. Its low moisture sensitivity helps preserve coating integrity and fiber performance in challenging operating environments, making it suitable for both telecommunications and specialty fiber applications.
The coating is engineered to support efficient manufacturing processes while helping minimize attenuation increases associated with fiber stress and microbending. Its proven combination of durability, adhesion, and environmental resistance makes it a practical choice for large-scale fiber production and recoating operations.
Supplied in a 10 kg container, DeSolite® 3471-3-14 is ideal for high-volume manufacturing environments requiring a reliable UV-curable single-coat optical fiber protection system.
