Description
The Tremco Spectrem 2 Structural Silicone Sealant – Clear (300 ml Cartridges) is a premium, high-performance sealant engineered for demanding glazing and perimeter sealing applications. Color: Clear, this professional-grade silicone is supplied in convenient 300 ml cartridges, with 30 cartridges per case. The transparent finish provides a clean, low-visibility appearance, making it ideal for glass-to-glass joints and architectural applications where minimal color impact is desired.
Spectrem 2 is a medium-modulus, one-part, neutral-cure silicone sealant formulated for both caulking and glazing uses. It is well suited for cap beads, toe beads, heel beads, and other typical air seals, offering 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 is ideal for sealing joints within curtain wall and window assemblies.
This high-performance silicone adheres to a wide variety of 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.
