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.

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.

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.

Works as advertised
Used as needed for a filler material in a 105/205 epoxy mix. Worked well. Needed more than I thought I would to get to the peanut butter consistency. Would have been better with the 206 hardener. Still happy with the results.
