Cabosil - Fumed Silica Thickener in Quart Tub

Thickened the gelcoat I used on my sons sailboat hull. Worked well. Thanks

Did exactly what I wanted too.

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

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

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

A good thickening agent for epoxy.

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

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.

I bought 2 of the containers for a rebuild of my boats hard top. It was recommended by a guy that does fiberglass work for a living. It works great by just adding some and stirring in until you get the consistency you need. The resin thickened quickly with small amounts added, keeping it from running past the intended work area. I also used a bunch to make a paste for some crack fills and it was excellent. I couldn’t detect any weakness in the filled areas either.

great for fiber glass thikiner
