Bostik 915 Polyurethane Sealant and Adhesive

Description

Bostik 915 is a one-component, smooth polyurethane adhesive designed for flexibility and durability. Capable of dynamic joint movement up to 70% of the original joint geometry (±35%), this sealant cures upon exposure to atmospheric moisture, forming a tough, flexible rubber. With an all-season formula, it maintains stable properties over time and withstands temperatures from -40°F to 150°F. For applications requiring a textured finish, Bostik 916 is recommended.
