Microbaloons

Premium Resin Filler for Fishing Swimbait Makers & Crafters

Microballoons.com supplies tiny hollow glass microspheres used as lightweight filler in resin systems. In swimbait and lure making, they are mixed into casting resin to reduce density without changing shape or strength — a 50% mix ratio produces lures that float.

Featuring silane-coated microspheres for superior resin bonding, producing structurally stronger end products that are easy to sand and shape. Trusted by hobbyists and professional lure makers worldwide.
