915 sealant is a one-component, smooth polyurethane adhesive capable of dynamic joint movement totaling 70% of original joint geometry (±35%). The sealant cures to a tough, flexible rubber when exposed to moisture present in the atmosphere.
Bostik 915’s all-season formula has physical properties that will remain stable over time. The cured performance temperature range is -40°F to 150°F. Where textured appearance is needed, please use Bostik 916.
