Silica Siwin-BQS151
Hydrophobic fumed silica
Characteristics
BQS151 is a pure, white powder that has been treated with DDS (dimethyldichlosilane) to make it hydrophobic. With a specific surface area of 150 ㎡/g, it has the following characteristics:
Applications
BQS151 is suitable for use in a variety of applications, including:
- RTV silicone rubber, particularly RTV-T
- Adhesives and sealants
- Coatings and printing ink
- Powder coating
Properties
BQS151 offers the following properties:
- Controls anti-setting, anti-sagging, and thixotropy
- Acts as an anti-settling and anti-sagging agent
- Controls rheology in adhesives
- Acts as a free flow aid and anti-caking aid for powders
- Provides thixotropy and reinforcement in RTV silicone sealants, with the added benefit of a long shelf-life due to its hydrophobic nature.
