Product Description

Product Description

Product Name:UV-2301 UV-curable Unsaturated Polyester Resin

1. Brief Introduction:
UV2301 is a remarkably reactive and medium-viscosity isophthalate neopentylene glycol type of unsaturated polyester resin. Stabilized and thickened with magnesium oxide, it cures swiftly under ultraviolet light, demonstrating exceptional glass fiber wettability, rapid curing speed, and superb mechanical properties. Perfect for UV-curing in trenchless repair (CIPP) of sewer pipelines, and oil and gas pipelines.

4 . Suggestions for Use:1) UV2301 resin can be thickened using magnesium oxide paste. The thickening viscosity and rate depend directly on the model and amount of magnesium oxide paste used.Thus, small batch trials are recommended before full usage.2) UV2301 resin can be cured
by *** lamp and UV-LED lamp. If considering other light sources for curing, please conduct small-batch trialsin advance.
5. Storage:
1) The product should be packaged in black IBC tanks or iron drums, as it contains a UV light initiator. Packaging must be stored in a dark place to remain completely 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. Shelf life is 6 months. Storage time decreases with rising temperatures.
