Glass Bubbles 1.0 lt

6.00 EUR / container of net volume 1.0 lt

Chemically composed of glass, their hollow form helps reduce matrix density. Their spherical shape prevents stress concentration and, as a consequence, increases cracking resistance of putties. In comparison to microballoons, they are physically harder, more waterproof and somewhat more difficult to sand. They have a fractional survival rate of 80% or more, for continuous use at 250 psi in highly filled resin systems. As a result, glass bubbles are also used as an additive for a number of buoyancy applications, in depths of up to 600 m in seawater. Suggested quantity to add in putties depends upon application.
