Product Description

Product Description

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

1. Brief Introduction:
UV2301 is a premium, highly reactive, medium-viscosity isophthalate neopentylene glycol unsaturated polyester resin.Formulated with magnesium oxide for stability and thickening, it cures efficiently under ultraviolet light. This resin boasts superior glass fiber wettability, rapid curing, and excellent mechanical properties. Ideal for UV curing trenchless repair (CIPP) of sewer, oil, and gas pipelines.

4 Suggestions for Use:1) UV2301 resin can be thickened with magnesium oxide paste, which directly influences thickening viscosity and rate.It is advisable to conduct small batch trials before full-scale application.2) UV2301 resin is compatible with *** lamps and UV-LED lamps. For other light sources, conduct preliminary small-batch trials.

5. Storage:
1) Package in black IBC tanks or iron drums to protect from UV light initiator degradation. Store in a 100% opaque, dark place.
2) Transportation must adhere to the State Council's 'Chemistry Dangerous Articles Safety Management Regulations'.
3) Avoid heat sources like direct sunlight or steam pipes. Keep sealed to prevent moisture absorption and monomer loss. Store in a dry place below 25ºC for a 6-month shelf life.
Storage duration decreases with rising temperature.
