TR-M 128

2023-11-13

1、 Features and main uses:

TR-M 128 is an ortho benzene type unsaturated polyester resin (modified) with high reactivity, medium viscosity, and good thickening stability. Its products are water resistant, have good toughness, and have excellent comprehensive mechanical properties. Used for producing SMC/BMC products such as low-voltage insulation parts, water tank boards, and automotive components.
