Additional Documents

This unique, weather-resistant formulation is ideal to withstand adverse conditions, including moisture, movement, sheer and deflection, in common installations. It is easily gunnable in all weather conditions from -20 to 120°F (-29-49°C). Because it requires no mixing and a smaller joint thickness requirement, it is an economical, high-performance alternative to other sealant options with a ±25 to ±40 percent movement capability.
