Evonik SIPERNAT® 383 DS Silica Powder
Categories:	Other Engineering Material
Material Notes:	Properties and applications: SIPERNAT represents a specific product range of precipitated silica, aluminum and calcium silicates. SIPERNAT 383 DS is a very finely ground silica with a slightly alkaline pH-value, which is particularly well suited for the production of in-situ hydrohobized defoamers. Due to an optimum pH-value of about 8-9 it facilitates for instance the hydrophobization process of defoamers. It is not necessary to add any catalyst. Information provided by Evonik
