System ThreeSilica Thickener, 5 Qt Tub, White

Building a mini tugboat. This filler thickens up epoxy resin very quickly. Seems to require a smaller amount than other fillers that I have used. When teh epocy cures, it makes for a very hard surface.

Great product works well

I added the silica to structural epoxy to repair a jet ski hull. This is an excellent product that mixes well with epoxy and provide strength. I can tell a significant difference between straight epoxy, and, epoxy mixed with silica. The straight epoxy sands very easily, but the silica epoxy takes several more passes for same results. It's easy to mix the silica into the epoxy, and I can guarantee you will not put in too much silica.

Definitely helped me fix my boat. Be sure to use sparingly and mix thoroughly before you add your hardener.

I find this stuff works great mixed with some Max Bond epoxy. Mix up the epoxy according to the directions and add some of this stuff until its like peanut butter and it makes a glue that, as far as I can tell, never comes apart. Add a little wood flour to the mix and you get a nice filler material too. This stuff is pretty particularized so its best if you use it outside or at least in a garage with the doors open. Not sure what happens if you breathe it in but I'm sure its not a good idea. If you are outside be careful, a good breeze will empty the bucket for you and it'll all be gone. Great product.
