Products in Transportation Assembly: Silica

HDK® H2000 is a synthetic, hydrophobic, amorphous silica produced via flame hydrolysis. It is a white colloidal powder of high purity. HDK® H2000 is primarily used as a reinforcing filler in silicone-elastomers, enhancing their properties. Furthermore, it serves as a free flow additive in the production of technical powders and finds application as an additive in antifoam agents.

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 106 is a hydrophobic fumed silica after treated with D4 (Octamethylcyclotetrasiloxane).

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.

Technicure® Nano Dicy is a pulverized grade of dicyandiamide. It contains fumed silica to prevent clumping and enhance flow. Its extremely fine particle size enables a more complete reaction, facilitating faster curing without compromising formulation shelf stability.
