Properties and applications: SIPERNAT represents a specific product range of precipitated silica, aluminum and calcium silicates. With its very finely ground size, a proper absorbency and an alkaline pH-value, SIPERNAT 350 provides an interesting combination of physico-chemical properties. One special application is the coating of high-quality heat-sensitive papers. In plant protection, this fine product is recommended as a carrier for acid-sensitive active ingredients in formulations like WP and WG. It is also recommended as low dust anti-caking agent especially in fatty powders. Furthermore, the small particle size makes it very useful for very thin polymeric films.Information provided by Evonik |
