Silica - Chemical Filler Silica is fumed silica. The purpose of adding silica in the production of topcoat is to increase the adhesion strength with the topcoat, so the amount of addition needs to be strictly controlled, but too much addition may affect the overall strength of the final paint film. . The reason is that silica is a porous structure. If you need to increase the overall strength of the paint film, you can consider adding aluminum silicate to the topcoat appropriately.

The dramatic improvement in the performance of modern winter tires also relies primarily on the use of silica in the tread compound. In addition to using silica as the main filler for car tire tread compounds, the use of silica in carcass compounds can further reduce heat build-up and rolling resistance. By using special high-dispersity silica, combined with high-structure fine-particle carbon black, the application of silica can be expanded, and they can be used in truck tires. The use of this good filling system can meet the main performance requirements of truck tires, that is, to reduce the hysteresis loss of the tire, thereby reducing the rolling resistance, and at the same time, maintaining the wear resistance.
