Product Description

Product Description

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. Formulated with magnesium oxide, it offers stability and thickening properties. This remarkable resin can be cured swiftly by ultraviolet lamps, delivering superior glass fiber wettability, rapid cure rates, and outstanding mechanical performance. Ideal for ultraviolet-cured trenchless sewer repair (CIPP) and for oil and gas pipeline applications.

4 . Suggestions for use:1) UV2301 resin can be thickened using magnesium oxide paste. The viscosity and thickening rate depend directly on the type and amount of magnesium oxide paste used.Conduct small batch trials prior to full-scale use to determine optimal conditions.So, small batch trials are recommended before use.2) UV2301 resin is compatible with *** and UV-LED lamps for curing. For other light sources, conduct small-batch trials beforehand to ensure proper curing.
2) UV2301 resin can be curedby *** lamp and UV-LED lamp, if you need to use other light sources for curing, please do small-batch trialsin advance.
5. Storage:
1) Store the product in black IBC tanks or iron drums. As the resin contains ultraviolet light initiators, ensure packaging is stored in a dark, 100% opaque environment.
2) Adhere to the State Council's 'Chemistry Dangerous Articles Safety Management Regulations' during transportation.
3) Avoid exposure to heat sources such as direct sunlight or steam pipes. Keep sealed to prevent moisture uptake and monomer loss. Store in a dry place at temperatures below 25ºC, with a shelf life of 6 months.
The storage time decreases with increasing temperature.
