Be sure to wear a good dust mask as this stuff is feather light & will blow all over, it weighs nothing. **Q: can this be mixed with bondo to thicken?** A: Yes this can thicken bondo. Just be careful because if you add to much your bondo will be dry. **Q: Is this hydrophobic or hydrophyllic?** A: CAB-O-SIL M-5 is widely used to provide thickening, thixotrophic (shearthinning), and anti-settling behavior in liquid systems. M-5 is most efficient in non-polar to medium polarity systems. M-5 offers the best balance of thickening efficiency and dispersibility ## Customer Reviews ### ⭐⭐⭐⭐⭐ No lumps Silica *by M***L on June 6, 2026* No lumps like other silica ### ⭐⭐⭐⭐⭐ Don't wait too long... *by M***R on June 6, 2026* worked great! ### ⭐⭐⭐⭐⭐ Arrived fast *by R***E on May 27, 2026* It's the gold standard for glass work ## Frequently Bought Together - Fasco Epoxies - Fasco Cab-O-SIL Fumed Silica thickener in Quart tub - TotalBoat 5:1 Marine Epoxy Resin Kit for Bonding, Filleting, Coating, and Laminating - Use for Fiberglass, Wood, Carbon Fiber, Boat Building, Repairs, Woodworking (Quart, Slow Hardener, Pumps) - TotalBoat-14409 Marine Gelcoat for Boat Building, Repair and Composite Coatings (White, Quart with Wax) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/69559867-fasco-epoxies-cab-o-sil-fumed-silica-thickener-quart](https://www.desertcart.tn/products/69559867-fasco-epoxies-cab-o-sil-fumed-silica-thickener-quart) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-12*
