一．Features and main uses:
TR886 is a modified unsaturated polyester resin synthesized from phthalic anhydride, maleic anhydride, and standard diols, dissolved in styrene. It exhibits medium viscosity and reactivity, excellent mechanical properties, and a high elongation at break, making it particularly suitable for winding processes. Glass fiber reinforced fiberglass tanks and pipelines exhibit excellent strength and toughness.

Note:
(1) Casting sample preparation method is carried out in accordance with GB/T8237-2005; temperature is 25℃, curing system: accelerator RCA 1.0%,
curing agent M-50 1.5%.
(2) Casting post-curing treatment: room temperature × 24 hours + 60℃ × 3 hours + 80℃ × 2 hours;
四．Notes:
1. Before use, stir thoroughly in the container, or empty all the resin from the container and stir thoroughly before use.
2. Transportation must comply with Chapter 5 of the State Council's "Regulations on the Safety Management of Hazardous Chemicals," regarding
the transportation and handling of hazardous chemicals. This product should be stored in a cool, dark place below 25°C, away from ignition sources
and heat sources. The shelf life is three months when stored below 25°C.
