Low price nano silica powder used as raw material CAS NO.7631-86-9

the nano-silica is analogous spherical particles produced by patent production technology. compared with the silica produced by gas phase method, the influence of our silica on improving the system viscosity is unapparent and the addition is up to 70%. high content addition can improve the properties of products such as abrasion performance, temperature tolerance, hydrolysis resistance, uv-stability and mechanical property. the silica with spherical or analogous spherical particles shows excellent performances such as high dispersion, chemical stability, acid and alkali resistance, surface activity, low oil absorption and insulating property, etc.

application:

• nano/micro sio2 which is widely applied in variety of areas such as coating, ink, silicone rubber, adhesive, defoamers, plastics possess performances as follows:
• improve the hardness, scratch resistance and the wearing quality of products prominently;
• fine anti-adhesive, avoiding latex agglutination;
• improve the pollution resistance, corrosion resistance, scrub resistance and the water-resistance of products;
• improve the adhesion of products, brighten the coating;
• enhance the ageing and uv ray radiation resistance of products;
• improve the printability of ink;
• increase the glossiness and fullness of products.

usages:

the silica powder should be first mixed with the matrix resin, and then other additives such as defoamer, flatting agent, wetting agents and thickening agent, etc.

the addition amount could be adjusted to users' requirement.

recommend amount：5%～50%.

suggestions:

the properties of thermal stability, storage stability, coating transparency and glossiness should be considered when selecting the sio2 product. if the existing sio2 product could not fit user’s system, we will provide one-to-one service, according different emulsion resin and formula to develop special sio2 product.

packaging and storage:

packing specification: 10kg/bag, 25kg/bag

packing material:sealed bags
