          2023-11-13

          1、 Features and main uses:

          TR-1023 series is an ortho benzene type unsaturated polyester resin (modified) with moderate reactivity, pre promotion, thixotropy, good glass fiber wettability, stable curing speed, and good construction performance. It has excellent water resistance and excellent comprehensive mechanical strength, making it suitable for the production of large-sized FRP products such as engine hood, automotive components, cooling towers, etc. using hand lay-up/spray molding processes.

          Among them, TR-1023WW is a winter type suitable for November March (below 15 ℃);

          TR-1023MM series spring and autumn type, suitable for April May, September October (15-25 ℃);

          TR-1023SS is a summer type suitable for June August (above 25 ℃).
