2. Why is silicone resin wear-resistant?
There are many modification methods for silicone resins, such as changing the organic groups on the side chains, grafting main chains, etc. These modification methods can improve the scratch resistance of silicone resin coatings.
Nowadays, the use of nanotechnology for modification has good development prospects. The preparation of resin-based nanocomposite coatings can help improve the wear resistance of coatings. On the one hand, the resin matrix can be modified. The interaction between the resin and the nanoparticles changes the thermodynamic properties of the system, thereby forming a special ordered structure. By changing the aggregated structure of the polymer chain, increasing the atomic force between molecules, and binding the chain Movement, reducing wear, thereby improving the wear resistance of the coating. On the other hand, introducing nano-fillers into the coating system can improve the mechanical strength and surface hardness of the coating.
