We recommend that customers around the 1 year warranty period to use. Application: High purity, high activity, high specific surface area, can be used for rubber reinforcing filler, rubber products to improve the tensile strength, tear strength and abrasion resistance. Common silica as good thixotropic properties and extinction, the following coating system can be common silica: Epoxy - tar paint, latex paint, nitro polishing paint, baking finish paint, unsaturated polyester varnishes, unsaturated polyester paint, acrylic enamel paint, air drying synthetic paint, hot vulcanized synthetic paint, chlorinated rubber - red aluminum paint, chlorinated rubber primer, zinc primer material. Add generic ink pigments of silica precipitation can prevent and control the viscosity of ink, colored ink to increase the sharpness. As a vitamin feed additive for filling the carrier.
