NYS2-N2-treated superhydrophobic nanosilica

NYS2-N2 is a kind of super-hydrophobic nano-silica independently developed by our company. It is a white loose powder treated with the surface chemical graft coupling agent hexamethyldisilazane. The product has small particle size, large specific surface area, strong UV absorption, visible light and infrared reflection properties. In addition to the advantages of hydrophilic products, the modified products have good compatibility with materials and strong dispersibility, and can also provide materials with waterproof and hydrophobic functions.

Application areas

　　1. Coating: After adding NYS2-N2 to acrylic anticorrosive coating, the suspension stability, smoothness, hardness, bonding between coating and substrate, strength and other properties are improved, while the drying time is shortened, the anti-aging time is increased, and the coating Improved stain resistance.

　 2. Plastic: NYS2-N2 is fully dispersed in plastic raw materials such as polypropylene (PP) and polyvinyl chloride (PVC), which can improve the strength, toughness, wear resistance and aging resistance of plastic products. In addition, it can also improve the waterproof performance of translucent plastic films.

　　3. Oil extraction: After adding NYS2-N2 during the oil extraction process, the oil-water separation efficiency can be improved.

　　In addition, this product is also widely used in unsaturated resins such as polyester to improve the strength, toughness and other properties of the material.

Instructions for use　

　　This product has good dispersion stability and superhydrophobicity in the system and can be directly used in materials. The recommended addition amount is based on weight: 0.1%-3%. The specific addition amount needs to be determined according to the actual situation.

　　Specific usage method of the product: Disperse the product directly into the system through mechanical dispersion and ball milling; or disperse the product in acetone, alcohols or other solvents, and then add it to the system.
