NOVELTY - Coating comprises a flexible epoxy sealing bottom coating, an organic silicone anti-adhesion middle coating and a fluorine silicone oil modified silicone rubber surface coating from inside to outside. The silicone rubber bottom coating comprises silane coupling agent, modified epoxy resin and polyether amine epoxy curing agent. The organic silicone oil-modified silicone rubber middle coating comprises 107 silicone rubber, crosslinking agent, nano filler, diluent and catalyst. The fluorine silicone oil modified silicone rubber top coating comprises hydroxy fluorosilicone oil modified silicon rubber, nano-filler, diol and catalyst. USE - The coating is useful for preventing fresh water shell vegetable from adhering, preventing and treating the fresh shell vegetable by changing the living environment of the fresh water vegetable and the method for constructing the biological chain. ADVANTAGE - The coating reduces the growth and attachment of aquatic organisms like fresh water shell vegetable and impurities in the tunnel and the inner wall of the pipeline in the water transportation engineering. The method is simple, convenient and easy to operate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing coating for preventing fresh water shell vegetable adhesion.
