916

916 is a one-component, textured polyurethane sealant designed for dynamic joint movement totaling 50% of the original joint geometry (±25%). When exposed to atmospheric moisture, the sealant cures to a tough, flexible rubber. With a consistency similar to toothpaste, Bostik 916 maintains stable physical properties over time and in varying weather conditions. Its performance remains relatively unchanged across a wide temperature range, from -40°F to 150°F (-40°C to 66°C). For applications requiring a smooth appearance, Bostik 915FS™ is recommended.
