Aerosil R 974
Applications
• Silicone rubber and silicone sealants
• Paints and coatings
• Negative toner
• Adhesives
• Coating polymers
Properties
• Hydrophobic component for thickening and reinforcement of RTV-1 pack silicone sealants.
• Improves shelf-life of silicone sealants.
• Water resistant, for thickening and hydrophobising of liquid systems.
• Rheology control of (complex) liquid systems.
• For use in coatings as
anti-settling agent, for pigment stabilization 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.
• Due to large surface area improved thickening and thixotropic effect as well as transparency.
