Abstract
A modified oxidic or silicate filler, comprising: at least one oxidic or silicate filler modified with a mercaptosilane of formula (I): (R1)3Si—R2—SH I, wherein the R1 substituents are identical or different and consist of alkoxy or alkyl, with at least one R1 group being an alkoxy group, and R2 is a divalent hydrocarbon group, or modified with an alkylsilane of formula (II): (R1)3Si—R3 II, wherein R1 is as defined above and R3 represents a saturated or unsaturated, branched or unbranched alkyl radical, and/or modified with silicone oil.
