Glass fiber reinforced plastic (FRP) is mainly composed of two raw materials: matrix material - resin; Reinforcement material - fiberglass. In addition, some trace additives need to be added when using, such as curing agent (Catalyst), accelerator (accelerator), inhibitor (Inhibitor), diluent (Diluent), etc. Glass fiber reinforced plastic (FRP) material is used in a very small amount, but the key material that determines the quality of the product - curing agent.
