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

Part Number: COV-751-020

The Covestro Cablelite® 751 Brown Optical Fiber Ink is a high-performance UV-curable coloring ink developed for optical fiber identification and color-coding applications. Designed for today's high-speed fiber manufacturing environments, this ink delivers rapid curing performance while maintaining the color consistency, opacity, and durability required for telecommunications-grade optical fibers.

Engineered to maximize production efficiency, Cablelite® 751 supports significantly higher coloring line speeds than many conventional UV-curable fiber inks. When used with high-power microwave curing systems, manufacturers can achieve exceptionally high processing speeds without compromising coating quality or curing performance.

Its low-viscosity formulation enables smooth processing across a wide variety of fiber coloring equipment, helping ensure consistent application and reliable production results. The brown color formulation meets EIA-359-A Munsell color requirements, providing excellent fiber identification and color differentiation even in low-light environments while maintaining optical performance.

Supplied in a 1 kg bottle, Cablelite® 751 is ideal for telecommunications fiber manufacturers requiring fast-curing, production-proven optical fiber coloring inks.
