  • Lightweight filler for epoxy
  • Easy to sand
  • Can be mixed with polyurethane

White micro balloons, also called glass bubbles, are super light hollow glass spheres that are ideal for thickening epoxy and PU resins into easily sandable fillers. Thanks to their low specific weight (0.10-0.20 g/cc) you can easily make light fillers that are excellent to work with.

Micro balloons are often used for making fillers, adhesives and lighter casting compounds. For optimum workability, a mixture of 1 part white microballoons and 1 part red micro balloons (by volume) is often used.

Applications

Thanks to their round structure and low density, white micro balloons are versatile in use:
