Waterproofing nano silica dioxide for car glass

This product is prepared by liquid-phase in-situ surface modification technology, when nanoparticles are generated originally, organic compound is modified on the surface of particle to realize the dimension control, at the same time, nanoparticles possess special performance. This product has good dispensability and stability in various organic medium such as toluene, carbon tetrachloride, painting, resin, coating, lubricant oil, injection augmentation agent and so on. The appearance seems true solution.
