| Features and main uses： | |||
| FN-H-2131 is a high activity m-benzene reactive flame retardant unsaturated polyester resin. The resin has good flame retardancy, low viscosity and good wettability to glass fiber. It is suitable for hand paste and RTM molding process. FN-H-2131 is used to manufacture FRP ships, vehicles, cooling towers, building components, cable boxes, coal mine parts and other flame retardant products. The products have good flame retardant self extinguishing performance, high mechanical properties, water resistance and other characteristics. When FN-H-2131 is combined with ATH, its products have the characteristics of high flame retardancy, slow flame propagation speed, low smoke density and water resistance. | |||

| Matters needing attention: | |||
| 1. High efficiency colorless accelerator should be avoided in the selection of accelerators, otherwise poor curing of products will easily lead to surface sticking, so RCA and other special accelerators for FRP should be selected. | |||
| 2. When the construction environment humidity is high or the temperature is high, it is easy to cause the surface to become sticky. At this time, rs-402 wax can be properly added, and the recommended addition amount is 0.4 ~ 0.8%. | |||
| 3. The product should be stored in a cool place below 25 ℃ to avoid fire and keep away from heat and radiation sources. The shelf life of products stored below 25 ℃ is 3 months. | |||
