TotalBoat Fiberglass Micro Balloons - White Glass Microspheres Filler for Epoxy Resin and Polyester Resin (5 Quart)

TotalBoat is one of the three main suppliers of marine/woodworking epoxy, and all their stuff is pretty good.We use West System most of the time, mostly because of familiarity and their awesome tech support, but sometimes TotalBoat has a good alternative.In this case, I generally prefer glass micro balloons such as this to the plastic ones for very low density filler as they're not as temperature sensitive (and cheaper).

Great

I like Totalboat products! I can trust they are selling high quality materials and at a reasonable rate! I use these microballoons mostly for mixing fairing compound, and I can adjust how much microballoons needed for particular areas instead of using the premixes. Works well everywhere else when needing to lighten up the resin, and makes sanding down easier! The little spheres mix in well, and the powder is consistent, no random big chunks. Totalboat makes some really good stuff!Good product! Great price! Awesome company!

Quality filler for bigger voids when working with polyester resins

I have used microballons for over 25 years in my hobbies - RC planes, gliders and boats. I know of only one name brand MFG that sells this product. It is a lot more expensive for a 1/4 of what you get with this product. I use this it for thickening two-part epoxy, speeding the curing time and once set, the material is sandable. If you need microballons, this is the stuff to buy!

Perfect for making thickened epoxy for my woodworking projects. Plus a lot cheaper than buying it when I can use my current epoxy to make it.
