Generally, amine curing agent is used. After curing, oily substances float out on the surface, which can not match well when bonded with vinyl resin. It is necessary to treat the cured surface before the subsequent anti-corrosion structure construction is carried out. If the treatment is not good, it is easy to layer and crack. According to experts, the bonding force between epoxy vinyl resin and concrete foundation is more than 2MPa, so epoxy vinyl resin as primer material has enough bonding performance. Therefore, it is recommended to directly use epoxy vinyl resin as primer material for priming, and the same epoxy vinyl resin is used for other layers.
