TotalBoat Silica Thickener (Cabosil)

TotalBoat Silica Thickener is an extremely fine high density epoxy filler that mixes to a smooth, non-sagging and easy to sand solution. Often used to control the viscosity of epoxy and commonly used on structural bonding, filling and filleting applications.

Material is also called colloidal or fumed silica, as well as cabosil, and can be mixed with epoxy on its own or added into a blend of epoxy fillers if necessary.

    Comments about System Three Silica Cab-o-sil Thickener:

    This product is great at doing all of the things it says. I find that the west system 404 filler is more dense and better for structural applications, but I add this filler to my 404 at the end of my mixing. I find that it gives the 404 a better thickness, reducing the sag, and making spreading much easier. Add a little at a time to get used how fast it gives the desired consistency. I do this same thing with microlight and other fairing compounds for the same reason, just use sparingly with fairing compounds as it can become more difficult to sand. Bottom line, great filler by itself, but is very effective when added top other fillers to get that just right consistency.

      Comments about System Three Silica Cab-o-sil Thickener:

      I purchased this product to thicken epoxy for gluing wood together. I am building a Guideboat and many joints are vertical, this product does well to thicken the epoxy and keep it from running. It is very light and fluffy, so when scooping it out of the container it is likely you will loose some as it 'poofs' out.
