Title:
SILICA AND ALSO EPOXY RESINS
Document Type and Number:
WIPO Patent Application WO/2009/109442
Kind Code:
A3
Abstract:
Fumed silicon dioxide powder in the form of aggregated primary particles having a BET surface area of 175 ± 15 m2/g and a thickening effect, based on the BET surface area, of greater than 18 mPas g/m2 is hydrophobicized with polydimethylsiloxane. This hydrophobic fumed silica has a BET surface area of 110 ± 25 m2/g. It can be used in epoxy resins. These epoxy resins in turn can be used as adhesives.
