915FS™

915FS is a one-component, fast-setting polyurethane sealant/adhesive designed for dynamic joint movement totaling 70% of the original joint geometry (±35%). When exposed to atmospheric moisture, the sealant cures to a tough, flexible rubber. The physical properties of 915FS remain stable over time and in varying weather conditions, with a performance temperature range from -40°F to 150°F (-40°C to 66°C). For applications requiring a textured appearance, Bostik 916 is recommended.
