Product Description

Product Description

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

1. Brief Introduction:
UV2301 is a highly reactive, medium-viscosity, isophthalate neopentyl glycol type unsaturated polyester resin known for its superior performance.. With the addition of magnesium oxide, this resin stabilizes and thickens effectively. It can be cured using ultraviolet lamps, offering excellent glass fiber wettability, rapid curing speeds, and outstanding mechanical properties. This makes it ideal for UV curing trenchless repair (CIPP) of sewer pipelines as well as oil and gas pipelines.

Note:The casting is prepared as per GB/T8237 guidelines. Curing conditions involve using UV LED LS128 with a light intensity of 14mW/cm2
, for a duration of 5 minutes.
4 . Suggestions for use:1) UV2301 resin may be thickened using a magnesium oxide paste. The thickening viscosity and rate are directly influenced by the type and quantity of magnesium oxide paste added.Hence, it is advisable to conduct small batch trials prior to full-scale application.thickening rate.So, small batch trials are recommended before use.
2) UV2301 resin can be curedusing *** lamps and UV-LED lamps. For other light sources, it is essential to perform small batch trials beforehand to ensure compatibility.in advance.
5. Storage:
1) The product should be stored in black IBC tanks or iron drums. Since the resin contains a UV initiator, the packaging must be kept in a dark, 100% 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. Keep containers sealed to prevent moisture absorption and monomer loss. Store in a dry place at temperatures below 25ºC. The shelf life is 6 months, but decreases with higher temperatures.
The storage time decreases with increasing temperature.
