West System 406-2 Colloidal Silica 1.7 oz

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.

Just sticking her really helps when I am trying to fill cavities or I need structural hold do recommend it

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.

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

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.

About this product to fix my Hoosier cabinet. it done a fantastic job.

Similar to other brand products and delivered very quickly. No complaints.

I've used this stuff for 40 plus years. Great for patching with epoxy and polyester.
