Product Description

Product Description

Product Name:UV-2301UV-curableUnsaturatedPolyesterResin

1. Brief Introduction:
UV2301 is a highly reactive, medium-viscosity isophthalate neopentylene glycol type unsaturated polyester resin.With magnesium oxide, it achieves stability and thickening, allowing curing by ultraviolet lamp. It boasts excellent glass fiber wettability, rapid curing speed, and superior mechanical properties. Ideal for UV curing trenchless repair (CIPP) of sewer, oil, and gas pipelines.

4 . Suggestions for use:1) UV2301 resin can be thickened using magnesium oxide paste. The thickening viscosity and rate are directly connected to the model and quantity of magnesium oxide paste used.Therefore, small batch trials are recommended before extensive use.2) UV2301 resin is curable by *** lamp and UV-LED lamp. For other light sources, conduct small batch trials in advance.

5. Storage:
1) Package the product in black IBC tanks or iron drums, as the resin contains an ultraviolet light initiator. Ensure the packaging drum is kept in a dark place and 100% opaque.
2) Transportation must comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations'.
3) Avoid exposure to heat sources such as direct sunlight or steam pipes. Keep sealed to prevent moisture absorption and monomer loss. Store in a dry place at temperatures below 25ºC with a shelf life of 6 months.
Storage time decreases with increasing temperature.
