Microballoons – System Three 3145S16 White Glass Microspheres, 1 quart Tub



5-star rated on Amazon, these are a great additive for any epoxy. These bulking agents are hollow, clear microscopic spheres that make a low cost, low density filler. Added to epoxy resin and hardener mix, they make a good, heat-resistant, light-weight fairing compound with good compressive strength. Mixture can be blended with a small amount of Silica Thickener to prevent sagging. Not recommended for glue. Alternatively use SilverTip QuikFair for ease-of-use.
