Fumed Silica Thickening Additive for Epoxy, Polyester Resin & Composite Applications

Cabot Cab-O-Sil Fumed Silica is a lightweight thickening additive designed for use with epoxy resins, polyester resins, adhesives, coatings, and composite fabrication systems.
Suitable for marine, woodworking, fibreglass, industrial, and composite environments, this fumed silica additive is commonly used to modify resin viscosity and create non-sag adhesive, filling, and fairing compounds.

Designed for professional fabrication and laminating applications, Cabot Cab-O-Sil Fumed Silica helps improve control and consistency when working with resin systems requiring thickened or gap-filling properties.

Its ultra-fine silica formulation is suitable for creating structural bonding mixtures, filleting compounds, fairing mixes, and controlled resin systems for marine, industrial, and composite applications.
