## Overview

Fasco Epoxies Cabosil Smoked Silica Thickener is a premium colloidal silica additive designed to dramatically increase viscosity and improve flow in epoxy and polyester systems. Its sub-micron, hydrophilic particles reinforce silicone and organic rubbers by boosting hardness, tensile strength, and stretch, making it an essential tool for professionals seeking flawless, high-strength coatings and sealants.

## Description

An excellent thixotropic agent used to control the viscosity of mixed epoxy systems. Can be used alone for a very smooth, non-sagging, high-strength mix, or combined with fillers or fibers to make them not saggy. Can also be used as a fly float. Also known as colloidal or smoked silica. CAB-O-SIL M-5 Smoke Silica is a medium surface smoked silica that allows a significant increase in viscosity in liquid polyester or epoxy system, allowing 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: Good product.
Review: Wish i could give this 11 stars, great epoxy thickener. Adds lots of structure and great price. Unless you are trying to 16ft boat worth of thick viscous paste, you'll never need more than a quart

## 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
