Cabosil - Fumed Silica Thickener in Quart Tub

We use this product to thicken silkscreen ink. Works well.

Mixes very well with resin. Perfect for crafting and much more cost effective than other products.

great for fiber glass thikiner

I used it to essentially fluff up flash powder by adding 1/10th of 1%to the mix. It allegedly makes the fire front from the point of ignition spread more rapidly throughout the total volume of flash instead of having the likelihood that some of the flash intended to go off get smashed at the ends of the shell while the inner part breaks the shell and wastes the powder at the ends un burnt. Use less flash, less power, but more boom! Its the lightest compound I have yet to handle and will actually begin leaving the tub upon opening, so wear a mask!

Smaller than expected but good

Hard as a rock

Worked great!! Used this to harden ceramic blanket for propane forge. Took a bit longer to dry than I wanted but was a lot cheaper than the premixed stuff.

Thickened up the gel coat to make repairs to my boat ... worked very good..

I’d previously bought the System Three fumed thickener to used in Epoxy resin. That stuff was super chunky. The Cab-O-Sil is much better. Very easy to mix to an even smooth consistency. I’m actually looking to create projects just for this.

I needed something to thicken some silicone fluid and this stuff did the trick.
