Tremco Spectrem 2 Neutral Cure Silicone Sealant – 20 oz, Medium Modulus Joint Sealant – AWF PRO Gloves Included – Black, Pack of 15

Spectrem 2 is a high-performance, single-component, neutral-cure silicone sealant designed for perimeter caulking, glazing applications, and two-sided structural glazing. Its medium-modulus formulation allows it to function both as a weather seal and as a structural tensile bead, making it a versatile, multi-use solution for commercial and industrial construction projects. Spectrem 2 delivers excellent adhesion to a wide range of substrates, including aluminum, glass, steel, painted metal, plastic, stone, concrete, and brick. This broad compatibility allows contractors to use one product across multiple applications on the same jobsite, reducing the need for additional sealants. Engineered for long-term exterior performance, Spectrem 2 offers exceptional weatherability, resisting UV exposure, temperature extremes, ozone, and driving rain while safeguarding against water penetration. It demonstrates a movement capability of ±50%, making it ideal for dynamically moving joints and building envelope applications. This ready-to-use sealant requires no mixing and applies easily with conventional caulking equipment. It is also fully compatible with Tremco silicone extrusions and SGT series tapes, and is GREENGUARD Gold Certified, making it suitable for use in sensitive environments such as hospitals and schools. Spectrem 2 is a reliable, high-performance solution for structural glazing, general glazing, perimeter caulking, and weather-sealing applications where durability, flexibility, and long-term performance are essential.
