The application of silicone leveling agent, coating in the film-forming process, may have shrinkage, fish eyes and other phenomena; construction viscosity and drying time, may also produce poor leveling phenomenon. By adding the leveling agent, the leveling agent can be quickly transferred to the surface of a paint film, so that the surface tension of the paint is reduced, the shrinkage cavity is reduced, and the pigment is prevented from floating to obtain a smooth coating film surface; and after the coating film is dried, the structure of the modified poly siloxane can enable the coating film surface to have a low friction coefficient, so that the surface smoothness and scratch resistance are improved, and the anti-adhesion effect is improved.
