Packing and storage

Packaged in multiple layer Kraft paper, 10kg per bag

They are inert and extremely stable chemically. However, due to their high specific surface area, they can absorb moisture and volatile organic compounds from the surrounding atmosphere. Therefore, we recommend to store the products in sealed containers in a dry, cool place, and removed from volatile organic substances. Even if a product is stored under these conditions, after a longer period it can still pick up ambient moisture over time, which could lead to its exceeding the specified moisture content. For this reason, our recommended use-by date is 24 months after date of manufacture. Product more than 24 months old should be tested for moisture content before use in order to make certain that it is still suitable for the intended application.

Silica Dioxide （TM325）

CAS:7631-86-9 White powder

It is the superfine precipitated silica made by special processing technology. It has excellent reinforcing and dispersing properties. it can completely or partially replace the Fumed silica and greatly reduce the production cost of customers.

It is applicable to strengthen the tire, rubber shoes and other products, improve the product"s flexural resistance, crack resistance and physical performance.

Good abrasive resistance, high strength and transparent properties are available, Prolong the use effect of the product

Silica Dioxide

（Silica Matting agent TM300）

CAS:7631-86-9

White powder

TM300 Matting agent powder is a special silicon dioxide precipitate made by gel process. It reduce gloss in coatings when solvents evaporate reducing the film thickness, this allows its particles to form a micro rug on the surface of the dried film, that disperses light rays reflecting on the surface.

Good matting efficiency and Good dispersion.

Application：paints, coatings, and ink
