Shanghai Gengyun Industrial Co., Ltd
An optical fiber inner coating resin suitable for UV-LED curing. It has excellent microbend resistance. It is suitable for high-speed drawing. It has low helium consumption and low odor.
Storage Conditions
UCR-037 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.
