Product Description

Product Description

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

1. Brief Introduction:
Experience the cutting-edge technology of UV2301, a highly reactive, medium-viscosity isophthalate neopentylene glycol type unsaturated polyester resin. Enhanced with magnesium oxide, this resin excels in stability and thickening. It cures swiftly under ultraviolet light, boasts superior glass fiber wettability, and delivers outstanding mechanical properties. Ideal for UV-curable trenchless repair (CIPP) applications in sewer, oil, and gas pipelines.

4 . Suggestions for Use:1) The 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, conducting small batch trials is highly recommended before full-scale use.2) The UV2301 resin can be cured
with *** lamps and UV-LED lamps. If other light sources are desired for curing, it is advisable to carry out small-batch trials beforehand.
5. Storage:
1) Package the product in a black IBC tank or iron drum. Due to the presence of ultraviolet light initiators in the resin, the packaging drum must be stored in a dark place, ensuring it remains 100% opaque.
2) Transportation must comply with the State Council's "Chemistry Dangerous Articles Safety Management Regulations."
3) Prevent exposure to heat sources such as direct sunlight or steam pipes. Keep sealed to avoid moisture absorption and monomer loss. Store in a dry environment at temperatures below 25ºC. The shelf life is 6 months.
Be aware that storage time decreases as temperature increases.
