1 Quart 100% Pure Fumed Silica Powder, Advanced Thickener for Epoxy, Paints, Varnishes, Professional Fumed Silica for Filling Cracks and Voids, Worked Well for Ceramic Blanket Rigidizer - by TITGGI

Was exactly what I expected. Haven’t used it yet, but have no reason to think it won’t work.

This product worked exactly as I had hoped it would. My only caution is that you open it in a room with still air, because it is extremely light--think of it as a container full of feathers: You wouldnt think of opening a container of feathers outdoors, so think you this product in the same way. As for how to use it: Mix your resin and hardener completely before adding the fumed silica. Then mix it thoroughly to eliminate any lumps before applying it to whatever surface or volume you intend to. It worked for me and it will work for you. I recommend it.

If you are looking for fumed silicate for the dry water science experiment this is not the correct kind and will not work. So glad we did a practice run before the birthday party.

Using fumed silica and chop fiberglass stran helps quiet abit to thicken epoxy.
