The excellent antifouling properties of silicone resin also depend on its unique chemical structure. Silicone resin contains a large number of silanol groups. During the film formation process, the silanol groups are dehydrated and condensed into a huge network structure, thereby forming an extremely dense film. paint film. This is also the reason why the silicone paint film has low surface energy and small surface tension. The surface contact angle of the modified silicone resin can reach 150°, which can make the coating have excellent hydrophobicity and theoretically have excellent antifouling properties.


①Polymer modified silicone resin
     Unlike silicone antifouling coatings, other polymer-based antifouling coatings also have unique antifouling properties. Therefore, the polysiloxane resin can remain stable by reacting with the reactive groups of the polysiloxane and other polymer resins. The main chain structure is grafted with other functional groups on its branch chains to ensure the anti-fouling effect and improve existing defects.

② Nanoparticle modified silicone resin
     Dispersing nanoscale filler particles in the chain segments of the silicone polymer through a high-speed mixer can improve the compatibility with the silicone resin and improve the antifouling performance of the coating. Among them, nanosilica is the most widely used because it has a similar molecular structure to organic silicon materials (the main chain contains Si-O-Si bonds).
