Covestro Cablelite® 751 Optical Fiber Ink, UV Cure (1 kg) - Black

Part Number: COV-751-008

The Covestro Cablelite® 751 Black Optical Fiber Ink is a UV-curable coloring ink developed for precision optical fiber identification in telecommunications and data communication cable manufacturing. Designed for high-speed production environments, this ink combines rapid curing performance with excellent color stability, enabling manufacturers to achieve reliable fiber identification while maximizing operational efficiency.

Cablelite® 751 Black is formulated to support modern fiber coloring lines where production speed and coating consistency are critical. Its fast-curing chemistry allows manufacturers to increase throughput without compromising cure quality, color opacity, or long-term performance. When paired with advanced curing systems, the ink is capable of supporting exceptionally high line speeds while maintaining dependable processing results.

The low-viscosity formulation promotes smooth application and compatibility with a wide variety of fiber coloring equipment. The black color meets EIA-359-A Munsell color specifications, providing strong contrast and clear identification for optical fibers used in telecommunications networks, data centers, and high-density cable assemblies.

Packaged in a 1 kg bottle, Cablelite® 751 Black is ideal for large-scale fiber manufacturing operations requiring durable, high-performance UV-curable color coding solutions.
