LOCTITE® SI 5615 is a premium adhesive sealant designed for bonding and sealing applications in industrial environments with temperatures up to 180°C. It is a two-part, fast-curing product with a thixotropic viscosity that offers excellent flexibility and wide substrate compatibility.
LOCTITE® SI 5615 is a room-temperature curing homogenous sealing paste with an alkoxy silicone base. It efficiently bonds to metal, glass, and Ceran® surfaces with fast bonding time, fixing in 12 minutes. LOCTITE® SI 5615 provides excellent hot strength capabilities to withstand temperatures up to 180°C (356°F), making it especially suitable for the bonding of glass stovetop assemblies and weld and rivet reduction in high-temperature applications.
