Product Description

Product Description

Product Name:UV-2301UV-curableUnsaturatedPolyesterResin

1. Brief Introduction:
Introducing UV2301, a highly reactive, medium-viscosity isophthalate neopentylene glycol type unsaturated polyester resin..Stabilized and thickened with magnesium oxide, this resin can be cured using ultraviolet lamps. It boasts excellent glass fiber wettability, rapid curing speed, and superior mechanical properties, making it the perfect solution for ultraviolet curing trenchless repair (CIPP) of sewer pipelines, as well as oil and gas pipelines.

for 5 minutes.
4. . Suggestions for use:1) UV2301 resin can be thickened with magnesium oxide paste. The thickening viscosity and rate are directly related to the type and amount of magnesium oxide paste used. Therefore, it is recommended to conduct small-batch trials prior to use.with the model and amount of magnesium oxide paste on the thickening viscosity andthickening rate.Hence, conducting small-batch trials is advised before application.
2) UV2301 resin can be curedusing *** lamp and UV-LED lamp. If alternative light sources are required for curing, it is essential to perform small-batch trials beforehand.in advance.
5. Storage:
1) The product should be packaged in black IBC tanks or iron drums. Since the resin contains ultraviolet light initiators, it is crucial that the packaging remains in a dark and completely opaque environment.
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. Ensure the container is sealed to prevent moisture absorption and monomer loss. Store in a dry place at temperatures below 25ºC, with a shelf life of 6 months.
Note that storage time decreases as temperature increases.
