Products in Construction Adhesives: Silica

AEROSIL® R 202 is a hydrophobic fumed silica grade, treated with a polydimethylsiloxane. This product can be used in defoamer formulations for sedimentation stabilization and due to its high hydrophobicity as defoaming component.

AEROSIL® 200 is a hydrophilic fumed silica with a specific surface area of 200 m²/g.

AEROSIL® R 972 is hydrophobic fumed silica grade treated with DDS (Dichlordimethylsilane). The moderate hydrophobicity of these AEROSIL® products is suited for defoaming properties in the presence of appropriate hydrophobic liquids. They are recomended for improving the sedimentation stability of defoamer dispersions as well.

AEROSIL® R 805 is a high thickening fumed silica surface treated with OCTMO.

AEROSIL® R 812 is hydrophobic fumed silica grade treated with HMDS (Hexamethyldisilazane). It can be used for sedimentation stabilization and due to its high hydrophobicity as defoaming agent.

VANSIL® HR-2000 Wollastonite is a high aspect ratio, short needle grade of wollastonite. It is used principally as a mineral filler and reinforcing agent to enhance mechanical strength properties in high build coatings, texture paint, block fillers, joint compounds and adhesives. In high film build coatings, the needle-like shape of VANSIL HR-2000 improves mud crack resistance and sag resistance, while also contributing to peak retention in texture coatings. The naturally high pH of wollastonite helps to buffer latex paints and coatings, which contributes to improved corrosion resistance and weathering. This also extends in-can stability and prolongs the lifetime of the coating. It is recommended that high aspect ratio grades of VANSIL be added late in process to avoid possible damage to the needle structure from high shear mixing.

Dispelair® P 864 is a foam control for the construction industry having the benefits of lower unit cost & used for general purpose.

Dispelair® P 540 is a new low carbon footprint powder foam control agent. Dispelair® P 540 has a much lower carbon footprint than a standard product, but with equal performance in self-leveling compounds.

Aktisil VM 56 is a sillitin Z 86 coated with vinyl silane.

SILFIT Z 91 is a Calcined product based on Sillitin Z 86.

SILLITIN Z 86 has a fine particle size distribution and good color neutrality.

AKTISIL VM 56/89 is a SILLITIN Z 89 coated with Vinyl silane.
