Micro Balloons

Convenient  bottle of Micro Balloons (Glass Spheres)

Microballoons are tiny, hollow spheres used as lightweight fillers in resins (epoxy, polyester) and other materials to reduce density, add bulk, and create easy-sanding putties for modeling, boat building, and composites, making them ideal for cosmetic fillets and lightweight structural bonding without adding significant weight

• Lightweight Filler: Significantly reduces the density of mixed resins, making them lighter.
• Easy Sanding: Creates fillers and putties that are much easier to sand than plain resin.
• Applications: Used for cosmetic joints, filling gaps, creating smooth fillets in model making, boat building, and even in aerospace composites.
• Compatibility: Works well with epoxy and polyester/vinylester resins (glass bubbles) 

Caution. Always wear a suitable particulate mask when using or handling!
