The spraying quality of FRP resin gelcoat directly affects the appearance quality, weather resistance, water resistance and chemical medium corrosion resistance of the product, so it is necessary to strictly control the coating of the gelcoat. Notes are as follows:
The quality of the epoxy vinyl FRP resin primer construction directly affects the bonding force between the FRP structural layer and the steel substrate. If the primer construction is sloppy, it will easily affect the adhesion of the coating, cause air bubbles, and may even peel off the entire layer of FRP.
The concept of composite material means that a material cannot meet the requirements of use, and two or more materials need to be compounded together to form another material to meet people's requirements, that is, composite materials.
