COUPSIL® + Precipitated Silica / Silane

In COUPSIL® products the silica is already pre-reacted with the silane. This makes the application of the Silica/Silane-system much simpler, because the complex silanization reaction in the mixer is obsolete. The product has only to be dispersed in the rubber like carbon black leading to significantly easier processing. Powder as well as granulates are available.
