Microballoons are tiny glass bubbles, that create an extremely lightweight filler when combined with resins and acrylic resins (such as Paraloid B-72). Micro-cellular, inert, non-toxic hollow glass particles.

Mixed with a 60-80% wt/vol Paraloid in acetone solution it can create a strong, conservation grade filler. Reasonable working time (ethanol can be added to the acetone solutionto delay setting but there is an enhanced toxicity). Can be shaped, sculpted and sanded. Takes a few days to cure to full strength.

Very fine particles (60 micron).

Please wear a respirator when using as particles easily become airborne due to their lightweight nature and tiny size. No specific hazards.
