Product Name:UV-2301 UV-curable Unsaturated Polyester Resin
1. Brief Introduction:
UV2301 is a highly reactive, medium-viscosity, isophthalate neopentylene glycol type unsaturated polyester resin.. Enhanced with magnesium oxide, it offers stability and thickening properties, can be rapidly cured using ultraviolet lamps, and boasts outstanding glass fiber wettability, rapid curing speed, and superior mechanical characteristics. Ideal for ultraviolet curing trenchless repairs (CIPP) of sewer pipelines, as well as oil and gas pipelines.

4 . Suggestions for use:1) UV2301 resin can be thickened using magnesium oxide paste. The thickening viscosity and thickening rate directly relate to the model and amount of magnesium oxide paste used.Small batch trials are highly recommended before full-scale application.2) UV2301 resin is compatible with *** lamps and UV-LED lamps for curing. If other light sources are considered, conduct small-batch trials in advance to ensure compatibility.
5. Storage:
1) The product must be packaged in black IBC tanks or iron drums to shield the resin, containing ultraviolet light initiators, from light exposure. It should be stored in a completely opaque environment.
2) Transportation must comply with the State Council's 'Chemistry Dangerous Articles Safety Management Regulations'.
3) Avoid exposure to heat sources like direct sunlight or steam pipes. Ensure the container is 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, which decreases at higher temperatures.
