The Tremco Spectrem 2 Structural Silicone Sealant – Black (300 ml Cartridges) is a high-performance, professional-grade sealant engineered for demanding glazing and perimeter sealing applications. Color: Black, this premium silicone is supplied in convenient 300 ml cartridges, with 30 cartridges per case, making it ideal for commercial construction, curtain wall systems, and storefront installations. The deep black finish provides a clean, uniform appearance for dark aluminum framing and modern architectural façades.
Spectrem 2 is a medium-modulus, one-part, neutral-cure silicone sealant formulated for both caulking and glazing applications. It is suitable for cap beads, toe beads, heel beads, and other typical air seals, delivering excellent flexibility and long-term durability. Spectrem 2 is particularly appropriate as a weather seal and tensile bead in two-sided structural glazing systems and performs reliably when sealing joints within curtain wall and window assemblies.
This high-performance silicone adheres to substrates including aluminum, glass, steel, painted metal, plastic, stone, concrete, and brick, often without primer. All structural glazing applications must be reviewed and approved by Tremco Technical Service prior to installation.
