Cab-O-Sil CAB-O-SIL-M5 (500-Gram-Ctnr)

Additional Product Information

Overview

CAB-O-SIL M-5 is an untreated fumed silica, a synthetic, amorphous colloidal silicon dioxide, widely used in aviation and MRO applications. Its ultra-fine particle size, high purity, and chain-forming properties make it ideal for enhancing material formulations, improving viscosity, and providing stability in adhesives, coatings, and composite materials. Maintenance teams rely on it for consistent performance, ease of handling, and superior quality in critical applications.
