S300

Silicon dioxide. Acts as a thickener and thixotrope in liquids. Improves the suspension behavior and redispersibility of solid in liquid system, dispersion and grinding aid. Increases the free flow and storage stability of powders. Helps in increasing flexibility and improving the ability to prevent chemical changes and pollution. Has high efficiency, extremely small particle size, enormous surface area, chain-forming tendency and extremely high purity. It is a white, fluffy, easily dispersible, fumed silicon dioxide powder, consisting of spherically shaped primary particles. It makes silica invisible in polymer films and clear lacquer. Recommended applications include defoamers, toners, printing-inks and coatings. Requires no hard sedimentation through long time reserving since it is treated.
