Product Description

Product Description

 

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

1. Brief Introduction:
UV2301 is a highly reactive and medium-viscosity isophthalate neopentylene glycol type unsaturated polyester resin. Enhanced with magnesium oxide, it offers stability and thickening properties. This resin cures rapidly under ultraviolet light, boasts superb glass fiber wettability, and delivers exceptional mechanical strength. Ideal for UV curing in trenchless repair (CIPP) of sewer lines and oil & gas pipelines.

4 . Suggestions for use:1) The UV2301 resin can be thickened using magnesium oxide paste. The viscosity and thickening rate are directly influenced by the type and quantity of magnesium oxide paste used.Thus, conducting small batch trials is highly recommended before full-scale application.2) The UV2301 resin can be cured using *** or UV-LED lamps. For other light sources, preliminary small-batch tests are advised to ensure compatibility.So, small batch trials are recommended before use.
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) The product should be stored in black IBC tanks or iron drums. As the resin contains UV light initiators, the packaging must be kept in a dark, opaque environment.
2) Transportation should 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. The shelf life is 6 months.
The storage duration decreases as ambient temperature increases.
