AEROSIL® R972 Fumed Silica

Description:

AEROSIL® R 972 is a hydrophobic fumed silica after treated with DDS (Dimethyldichlorosilane) based on a hydrophilic fumed silica with a specific surface area of 130m2/g

Applications:

Silicone rubber and silicone sealants
Paints and coatings
Printing inks and toner
Adhesives
Cable compounds and gels
Plant protection

Properties:

Hydrophobic component for thickening and reinforcement of RTV-1 K silicone sealants.
Improves shelf-life of silicone sealants.
Water resistant, hydrophobising of liquid systems.
Rheology control of (complex) liquid systems.
For use in coatings as anti-settling agent, for pigment stablilization and improvement of corrosion protection.
Improves hydrophobicity and rheology of offset printing inks.
Improvement and maintenance of free flow and anti- caking characteristics of powders.
