By simply adding the desired amount to your mixed resin, you can customize the consistency from a brushable coating to a thick structural adhesive or filleting compound. This versatile thickening agent is widely used in marine repair, boat building, fiberglass fabrication, composite construction, woodworking, automotive restoration, and industrial applications. It helps prevent resin from running or sagging on vertical and overhead surfaces, making it ideal for bonding, gap filling, filleting, laminating, and structural repairs where precise placement and control are essential. Cab-O-SIL also improves the handling characteristics of epoxy systems by producing smooth, easy-to-apply mixtures that maintain excellent workability while increasing stability. It can be used alone or combined with reinforcing fillers such as milled fiberglass, chopped fibers, graphite powder, microballoons, or wood flour to create custom compounds for specific applications. Whether you're repairing fiberglass boats, laminating composite parts, bonding wood, filling joints, or creating high-strength structural fillets, Fasco Cab-O-SIL provides the versatility and performance trusted by professional fabricators, boat builders, and DIY users alike. Common Applications Thickening epoxy, polyester, and vinyl ester resins Marine and fiberglass repairs Boat building and composite construction Structural bonding and adhesive applications Fillets and radius joints Gap filling and crack repair Vertical and overhead laminating Woodworking and furniture repair Automotive fiberglass restoration Mold making and composite fabrication Directions: Add Cab-O-SIL gradually to properly mixed resin while stirring until the desired consistency is achieved. Use smaller amounts for brushable coatings and progressively more material for gap filling, bonding, or non-sag structural applications. Always wear appropriate personal protective equipment and avoid breathing airborne dust during handling. ## Features - TURN THIN EPOXY INTO A HIGH-STRENGTH ADHESIVE – Fasco Cab-O-SIL Fumed Silica transforms low-viscosity epoxy, polyester resin, vinyl ester resin, silicone, paints, and coatings into a smooth, non-sagging mixture ideal for bonding, filleting, gap filling, and structural repairs. - PROFESSIONAL MARINE & COMPOSITE APPLICATIONS – Ideal for fiberglass repairs, boat building, marine maintenance, woodworking, automotive fiberglass, composite construction, mold making, and general industrial projects.
