West System awesomeness
I’ve dealt with a couple of epoxy brands over the years and West System’s is by far the best all around system that includes both epoxy and fillers. These fillers are a bit pricy when you factor in the weight or volume but they work just like fillers should. I have yet to encounter any negative issues with these fillers, and they all appear to be packaged in a professional environment. The fillers come bone dry and don’t have any impurities in them.

Works great as an epoxy thickener
I mixed some of this colloidal silica with a 2 part epoxy glue to thicken it up. The more you add the thicker the glue mixture gets. The powder is super light, and floats everywhere, so a mask is not a bad idea. Handle it slowly and carefully.

Good to Have
Here in Hawaii, even Ace Hardware doesn't have this. Thank you for Amazon to sell this.

Amazing Product
Used it to add to gelcoat during a crack repair on our boat and it is amazing. ALWAYS USE A RESPIRATOR!!! This is a very fine dust and it will damage your lungs.
