Major Applications and Performance Features:
Typical Applications CAB-O-SIL fumed silica is used for rheology control in a wide variety of adhesives, composite and coatings applications:
Epoxy Adhesives and Coatings:
In epoxy adhesives and coatings, fumed silica provides good thickening efficiency, sag resistance (or film build) and
anti-settling of pigments and fillers. For applications requiring storage stability, fumed silica is recommended.
Polyurethane Adhesives and Coatings:
In polyurethane adhesives and coatings, fumed silica provides the same efficient, stable rheology control as in epoxy systems. In addition, the hydrophobic surface of fumed silica introduces very little moisture into these systems preventing
premature cross-linking of moisture cured systems.
Vinyl Ester Laminating Resins and Gel Coats:
While untreated silicas are effective thickeners of unsaturated polyester resins, CAB-O-SIL
fumed silica is a more efficient, stable rheology control additive for higher polarity systems like vinyl ester laminating resins and gel coats.
