Offering weight savings without degradation of mechanical properties, Tough Class A Ultra Lite® uses treated glass bubbles to replace some CaCO3, allowing resin to adhere to matrix and increase interfacial strength between bubble and resin. Technology results in resin mix that makes molded parts resistant to handling damage, and prevents micro-cracks that cause paint pops, pits, and blistering. Treated bubbles also help with paint adhesion and bonding characteristics.
