AEROSIL R 805 Hydrophobic fumed silica 92 797-60-9 Degussa-Silanes Corrosion inhibitor Rheology Modifier/ Thickener Coatings Powder coating AEROSIL® R 805 is a fumed silica aftertreated with an octylsilane based on AEROSIL® 200. It possesses an effective rheology control in complex liquid systems (e.g. 2 pack-epoxy coatings), can be applied in coatings systems as an anti-settling agent, for the stabilization of pigments and to enhance the effect of corrosion protection, free flow aid in powder coatings. It is used in paints and coatings systems, adhesives and sealants, epoxy multicoat systems. Hydrophobic fumed silica. Used in paints and coatings systems. Provides stabilization of pigments and to enhance the effect of corrosion protection. Offers free flow aid in powder coatings. Possesses an effective rheology control in complex liquid systems(e.g. 2 pack-epoxy coatings).
