Spherical nano-silica as a versatile active ingredient, can be tailored for different industries. Xinlei spherical nano-silica powder will make the most of our clients greatly benefit from, with many targeted silica products, but also according to customer's need to provide unique and innovative products and provide technical services. For the modified resin-based composite materials, solid white mass, particle size uniformity, and the infiltration of various types of resin mixed with good absorption characteristics of good, easy blending, suspension characteristics significantly. Effectively eliminate or reduce sedimentation, stratification, with good technical characteristics, when mixed with various types of epoxy resin, in addition to adsorption, but also can form a chemical bond, in close to casting, the formula after adding silica powder cured epoxy resin reduces the peak temperature of exothermic reaction, lower curing shrinkage and linear expansion coefficient, reducing internal stress, effective in preventing cracking of cured, more overall improvement in their performance, increase strength, toughness, elongation, resistance to wear resistance, finish, anti-aging and so on.
