Presentation Abstract

New treated fumed silica grade for emerging adhesive and sealant applications

Cabot CAB-O-SIL® Treated fumed silicas have been widely used in adhesives and sealant formulations as standard rheology modifiers.  A growing trend in the construction and automotive market for adhesives and sealants is to provide superior strength and adhesion, and sometimes high transparency on various substrates. To address the need for high performance adhesives and sealants, Cabot is launching a new treated silica grade, CAB-O-SIL® ULTRABOND™ 5780 fumed silica.  

In this work, we will present the unique properties and performance of CAB-O-SIL® ULTRABOND™ 5780 treated silica in transparent sealants based on silane-modified polymer and epoxy structural adhesives.
