Flame retardant Application Principium: I. Mg-Si-Al powder has stable chemical property and good weather resistance, so it can be applied in paint & coating of inside and outside wall and it can apparently increase the hiding capability of comprehensive stuffing. II. Mg-Si-Al powder can increase the fluidity of paint and the impression and hand feel of coating no matter it is used in oil paint or water paint because it can make the coating soft, lubricating and bright and can increase its resistance against scrubbing. III. Mg-Si-Al powder has big hardness, so it can be used to manufacture wearable road lineation lacquer and wearable material. IV. Mg-Si-Al powder is refractory, and it has complete crystal and good chemical resistance. It can be used to manufacture anti-corrosion coating, fireproof coating and the coating of all sorts of special uses. V. Mg-Si-Al powder has perfect lubricity and dispersion. It has the function of exquisite talcum powder in coating because it can increase the brushing performance and construction performance of all sorts of paints. The use of Mg-Si-Al powder in all sorts of paints can make the coating stable and do not appear post-thickening phenomenon like Kaolin
