1,Brief Introduction:
TM-25 is kind of Orthophthalic resin, pre-accelerated type. The resin has the low viscosity, high strength, good toughness, and good wettability to glass fibers. It is suitable for vacuum diversion and RTM molding processes. It can be sued for FRP fishing boats, automobile parts, and fans Engine compartment cover and waterproof board and other products. This product has been approved by CCS .
