Application

Hydrophobic grade is applied as a thickening and thixotropic agent in coatings, printing inks, adhesives, cosmetics and others. It is used as a reinforcing filler in elastomers, mainly silicone-elastomers. It acts as a free flow additive in the production of powder coatings. In toner and powdered copier, It improves anti-cake, moisture resistance and free-flow properties; it also stabilizes the electrostatic charge. 

Storage

4 years from production date.

 

It should be stored in the original packaging in dry storage areas.

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons. 

Packaging

*0 kg bags or drum.
