High Modulus Silicone. Structural Strength. Lasting Seal.

Arbosil High Modulus Silicone Sealant is a professional-grade, one-part silicone formulated for structural glazing, curtain walling, and demanding weathersealing applications where a firm, high-strength cure is required. High modulus silicone cures to a harder, less flexible finish than low modulus alternatives — making it the right choice where movement is minimal and bond strength is the priority.

Supplied in a 310ml cartridge in Brown, suitable for use with a standard skeleton or sealant gun.
