For systems that require wear resistance, in addition to increasing the crosslinking density from the perspective of the resin, adding additives is also a common method, and the use of silicone additives is a commonly used method. Common ones include ultra-high molecular weight silicone microspheres, ultra-high molecular weight silicone emulsions, and silicone nano-modifiers.
Ultra-high relative molecular weight wear-resistant silicone microspheres are a dispersion of high relative molecular weight polysiloxane with a slightly cross-linked structure inside, which is microscopically microspherical. After being added to the system, it will eventually be oriented on the surface of the paint film. Forms a polysiloxane film that provides the system with excellent slip and surface abrasion resistance.

In water-based coating systems, in addition to silicone microspheres, ultra-high molecular weight silicone emulsions are also commonly used as a type of anti-wear additives. They are usually obtained by polymerization of silicone emulsions, and the internal phase viscosity is extremely high. It can reach millions, and after being added into the system to form a film, a layer of ultra-high relative molecular weight organic silicon thin layer can be formed on the surface, thereby improving the wear resistance of the paint film.
