Great scilica fumed is the only way to have your errant silica

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.

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.

Great bang for your buck here. I specifically used this to rigidize some kaowool and it worked great. Way cheaper than shipping a liquid ridgidizer. Works great to thicken epoxy too.

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