Cabosil - Fumed Silica Thickener in Quart Tub

I used this product to thicken epoxy resin repair on a boat transome. Worked fine.

great for fiber glass thikiner

Used as rigidizer for my kaowool in my forge seemed to work perfect. Time will tell.

I have I only use it once to thicken up my epoxy so it wouldn’t run as fast. It did the job.

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

Good peanut butter for my boat refurb. No problems. Also worked perfectly on the gelcoat as well. Could be at a better price...

It did exactly what I bought it for.

Thickened up my resin for mold making. But not a lot of value per ounce. Seems a little pricey for the small amount you’re getting.

I needed to fill holes in Banksia handles I was making. The Cabosil worked fine for my project. It is light and fluffy so precautions need to be taken to avoid inhaling the product. With care it is no problem to use safely.

I use this as part of a recipe (the other part being water) to make my own rigidizer for ceramic wool. Much cheaper than buying already prepared rigidizers.
