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

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.

This is the right silica to get to mix up your own rigidizer.

I use this to thicken my last epoxy cast pour. I cast trout head with epoxy smooth on and I use this for last pour to thicken and strengthen it and it works great.

I am an artist that works with multiple mediums, and one of them is epoxy. I wanted a thickener to use in my epoxy to make 3D whipped cream and potions around the top of my epoxy tumblers. This worked brilliantly. The amount of thickener you use really varies depending on how thick you want the epoxy, and the amount of epoxy you are working with. For my smaller cup projects, this tub will last me quite a while, and I am loving the results. This thickener is the best value I have found for price, quantity, and efficacy.

Works as it should when mixed with polyaspartic for filling concrete cracks.

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.

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

The seal cover was opened on this product, yellowish and weird odor!!!

Works great

I cant always get really flat paint for small touch-up latex samples. Matt samples are not perfectly flat paint and shine on pre-painted surfaces. The silica powder kills any sheen and makes the latex samples thicker for drip free applications on ceilings or walls. I mix the silica and latex in small tins and let sit for a minute or two before applying. I little goes a long way, use fractional teaspoons per ounce of paint.
