Product Description
SikaLastomer®-511 is a one-part, non-skinning and non-corrosive butyl-rubber sealant for factory sealing standing-seam roof and wall panels and concealed end laps. The off-white material remains malleable after application, allowing metal panels to be separated later for repair or maintenance. It is applied to clean surfaces using manual, pneumatic, electric, or pump equipment within a documented application-temperature range of 5°C to 40°C. The sealant has a typical uncured density of 1.09 kg/L and a service-temperature range of -50°C to 105°C.
Key features
- Non-skinning butyl sealant: The material remains malleable after application and supports later panel separation.
- Factory-to-field assembly window: Panels may be joined in the field up to six months after initial application under the documented conditions.
- Wide service range: The documented service-temperature range is -50°C to 105°C.
Applications / Suitable for
- Factory sealing of standing-seam roof panels
- Standing-seam wall panels
- Concealed panel end laps
