Its sub-micron particle size and thixotropic properties ensure smooth, non-sagging, high-strength mixtures, making it a must-have for professional-grade formulations. ## Description An excellent thixotropic agent which is used to control viscosity of mixed epoxy systems Can be used alone for a very smooth, non-sagging, high strength mixture or combined with fillers or fibers to make them non-sagging can also be used as fly floatant Also referred to as colloidal or fumed silica CAB-O-SIL M-5 fumed silica is a medium surface fumed silica which enables a significant increase in viscosity in liquid polyester or epoxy systems, free flow of high purity powders and reinforcement of silicone and organic rubbers. Aggregated structure Sub-micron particle size Low bulk density Hydrophilic surface Review: Fasco Epoxies Cabosil Review: Good product ## Features - Hydrophilic surface - When blended into sticky and poorly flowing powder systems, Cabosil reduces angle of repose and improves powder flow. - Can be used for reinforcement of silicone rubber and can be used to reinforceorganic rubbers - Imparts good increase in hardness, tensile and elongation. Imparts significant increase in viscosity in liquid systems - Also referred to as colloidal or fumed silica ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B074Y6V7QT | | Brand | Fasco Epoxies | | Brand Name | Fasco Epoxies | | Colour | Clear | | Compatible Material | Rubber | | Container Type | Pail | | Customer Reviews | 4.6 out of 5 stars 756 Reviews | | Global Trade Identification Number | 00819794020756 | | Item Form | Powder | | Item Package Quantity | 1 | | Manufacturer | Fasco Epoxies Inc. | | Material | Silicon Dioxide (Silica) | | Material Type | Silicon Dioxide (Silica) | | Model | FIL01Q | | Other Special Features of the Product | Thixotropic | | Special Feature | Thixotropic | | Specific Uses For Product | Epoxy Systems, Silicone Rubber, Organic Rubbers, Mixed Systems, Reinforcement, Viscosity Control, Non-Sagging Applications, Fly Floatant Specific Uses For Product Epoxy Systems, Silicone Rubber, Organic Rubbers, Mixed Systems, Reinforcement, Viscosity Control, Non-Sagging Applications, Fly Floatant See more | | UPC | 819794020756 | | Viscosity | medium | | Volume | 1 Quarts | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** Fasco Epoxies - **Item Form:** Powder - **Material:** Silicon Dioxide (Silica) - **Special Feature:** Thixotropic ## Images ![Cabosil - Fumed Silica Thickener in Quart Tub - Image 1](https://m.media-amazon.com/images/I/61fWIw8bQwL.jpg) ![Cabosil - Fumed Silica Thickener in Quart Tub - Image 2](https://m.media-amazon.com/images/I/51CY5P5CXTL.jpg) ![Cabosil - Fumed Silica Thickener in Quart Tub - Image 3](https://m.media-amazon.com/images/I/31E8mBh0McL.jpg) ![Cabosil - Fumed Silica Thickener in Quart Tub - Image 4](https://m.media-amazon.com/images/I/41URJiyuDKL.jpg) ![Cabosil - Fumed Silica Thickener in Quart Tub - Image 5](https://m.media-amazon.com/images/I/31PjRiYEAdL.jpg) ## Questions & Answers **Q: How should I dispose of it safely?** A: In the container it came in **Q: Is cabosil hs5 equivalent to cabosil m5?** A: Works good, you just have to keep adding a little at a time to your pre mixed resin/hardener mix until you get the right consistency for your job. 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 ### ⭐⭐⭐⭐⭐ Fasco Epoxies Cabosil *by A***E on 11 January 2026* ### ⭐⭐⭐⭐⭐ Good product *by J***D on 24 February 2026* ### ⭐⭐⭐⭐⭐ Use less than half your resin volume *by R***D on 19 February 2026* ## 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.vn/products/451479849-cabosil-fumed-silica-thickener-in-quart-tub](https://www.desertcart.vn/products/451479849-cabosil-fumed-silica-thickener-in-quart-tub) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-24*
