Optical Fiber Outer Layer UV Coating Resin

An optical fiber outer coating resin suitable for UV-LED curing. It has high peel force, low PMD, excellent mechanical properties after aging and low odor.

Storage Conditions

UCR-017 is a light-curing uv led coating. The bottle containing the coating is opaque to UV light, including sunlight and fluorescent light. The coating should be stored at a temperature range of 15°C to 30°C.
Storage and transportation at low temperatures may cause phase separation, which is reversible and can be restored by heating at 50°C for 24 hours.

Shelf Life of UV Coating Resin

UCR-037 has a shelf life of 12 months from the date of production if stored properly as described above.

Safety Information

This product may irritate the skin and eyes or cause skin allergies. All safety and handling instructions should be strictly followed.

Filtration

UCR-037 uses advanced filtration technology during the production process. This technology is used to avoid fiber strength problems while ensuring consistent product performance.
