Product Name:UV-2301 UV-curable Unsaturated Polyester Resin
1. Brief Introduction:
UV2301 is an exceptionally reactive, medium-viscosity isophthalate neopentylene glycol type unsaturated polyester resin.. Stabilized with magnesium oxide, it boasts excellent thickening properties. Cured by ultraviolet light, it offers superb glass fiber wettability, rapid curing, and outstanding mechanical characteristics. Perfectly suited for ultraviolet curing trenchless repair (CIPP) of sewer pipelines, as well as oil and gas pipelines.

4 . Suggestions for use:1) UV2301 resin can be thickened with magnesium oxide paste. The model and quantity of magnesium oxide paste directly affect thickening viscosity and rate.Small batch trials are strongly recommended before full-scale use.2) UV2301 resin can be cured using *** lamps and UV-LED lamps. For other light sources, conduct small-batch trials beforehand.
5. Storage:
1) The product must be packaged in a black IBC tank or iron drum. As the resin contains an ultraviolet light initiator, the packaging must remain in a dark place and 100% opaque.
2) Transportation should adhere to 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. The storage period decreases as temperature increases.
