Coating: S-515 ultra-small particle size silica sol can be used in high-grade coatings and special coatings, in the same amount of silica sol the number of particles and the contact point of the rapid increase, so that it has a bonding performance, increased film strength and coating, can be used in high-grade coatings and special coatings. Paper making: S-515 ultrasmall size silica sol has the characteristics of large specific surface area and high reactivity. It can bond well with cationic Surfactant and pulp fibers and play the role of retention and drainage, improve the retention rate of fine fiber and filler, as well as the dehydration performance of slurry. The paper is coated with silica sol of super-small particle size as additive material, which can play the function of paper waterproof.
