Product Characteristic:
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 increase agent,the appearance seems as true solution.
Usage Instruction: This product is organic modification nano-SiO2, has extra strong hydrophobic and super oleophilic, and can dispersed in non-polar and weak polar organic solvent with transparent state. Mainly applied in lubricant grease, resin, glue, elastomer, high ink, sealing agent, car wax, leather, anti-corrosive paints etc..
