High Viscosity Secondary Coating Resin for Optical Fiber

• Molecular Principal Chain: Element Organic Polymer
• Color: Customized
• Transport Package: Standard
• Specification: High Viscosity Secondary Coating
• Origin: China
• Model NO.: T- RT2886

Product Description

T-RT2886 is a high viscosity, designed for high speed optical fiber drawing secondary coating
Product Characteristics

 Low volatile content, less condensation on cooling tubes

 Suitable for wet-on-dry drawing processes

 Higher viscosity, faster drawing speed, good for non-helium drawing condition

 Combining with RT series primary coating and inks for even better results
