Deluxe Materials Microballoons is an ultra-lightweight hollow microsphere filler designed for creating low-density filling compounds and reducing weight in model building, composite construction, and aeromodelling applications. Commonly mixed with epoxy, polyester resin, cyanoacrylate, and other adhesives, Microballoons create a smooth, easily sanded filler ideal for contouring, fairing, gap filling, and surface finishing. The hollow microsphere structure significantly reduces the weight of filler mixtures while maintaining excellent workability and sanding characteristics. Widely used in RC aircraft, scale models, boats, composite structures, and advanced hobby projects, Microballoons help modelers achieve smooth, professional finishes without adding unnecessary mass.
