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.. Enhanced with magnesium oxide, this resin is stable, thickens effectively, and cures rapidly under ultraviolet light. Boasting excellent glass fiber wettability and superior mechanical properties, it is ideal for UV-curing trenchless repairs (CIPP) of sewer and oil & gas pipelines.

4 . Usage Recommendations:1) UV2301 resin can be thickened with magnesium oxide paste. The thickening viscosity and rate are influenced by the specific model and amount of magnesium oxide paste used.Small batch trials are highly recommended before use to ensure optimal performance.
2) UV2301 resin is compatible with *** and UV-LED lamps for curing. For other light sources, preliminary small-batch trials should be conducted.
5. Storage:
1) Package the product in black IBC tanks or iron drums, as the resin contains ultraviolet light initiators. Store the packaging containers in dark locations to ensure 100% opacity.
2) Compliance with State Council's 'Chemistry Dangerous Articles Safety Management Regulations' is required for transportation.
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. The product has a shelf life of 6 months.
Note: Storage time decreases with increasing temperature.
