High specific surface area (~170 m²/g) for superior reinforcement and thickening efficiency.
Hydrophobic surface treatment with dimethoxydimethylsilane, ensuring excellent dispersibility in non-polar systems.
Low density and free-flowing powder morphology for easy handling and consistent dosing in automated processes.
Consistent batch-to-batch quality supported by WACKER’s stringent GMP-aligned manufacturing control.
Non-hazardous classification under CLP regulation — no labelling as hazardous substance (EU).
High-performance silicone rubber compounds requiring tear strength and compression set resistance.
Two-component polyurethane sealants and adhesives needing thixotropic control and sag resistance.
Industrial coatings and inks where rheology modification and anti-settling functionality are critical.
Food-grade and pharmaceutical-grade silicone elastomers complying with FDA 21 CFR §177.2600.
Specialty composites including thermal interface materials and flame-retardant polymer formulations.
