This document describes Astec, a water-based acrylic elastomeric ceramic coating that can be applied to various substrates. It has been used on over 28 million square meters of surfaces for more than 20 years to provide insulation, protect against corrosion, and stop leaks. The coating reduces surface temperatures and energy consumption, and can extend the lifespan of structures at a lower cost than conventional re-roofing. It has benefits for roofing, walls, tanks, vehicles, and other industrial and military applications.
