Description for SMC:
The formula is specially designed for products requiring very high strength. The resin, thickening agent, release agent, filler, mixed high temperature curing agent, coating in the 2 films, fiberglass direct roving and fiberglass chopped strand, sprinkle in the coating resin paste film, the 2 layer composite thin film, the glass fiber soaked through automatic packaging, folding machine, and then in the drying room temperature through thickening time, achieve the molding viscosity requirements, namely into finished products.
