Product Overview
Tremco Spectrem 2 is a medium-modulus, high-performing, one-part, neutral cure silicone joint sealant. As a medium modulus sealant, Tremco Spectrem 2 has excellent physical properties that makes it very suitable for a variety of perimeter caulking and glazing uses and can be used as a structural tensile bead and weather sealant. This silicone sealant is specifically designed for two-sided structural glazing, perimeter and weather sealing. Tremco Spectrem 2 can also be used for cap, heel and toe beads, as well as curtainwall and window joints. Tremco Spectrem 2 provides resistance to driving rain, ozone, ultraviolet light, temperature extremes and safeguards against water penetration with exceptional weatherability in all climate zones. Common substrates where Tremco Spectrem 2 can be applied to are steel, aluminum, glass, painted metal, plastic, stone, brick and concrete. Adhesion is obtained without the need of a primer when applied to most construction materials. No mixing required when using Tremco Spectrem 2 so this silicone sealant is always ready to use for immediate application with conventional caulking equipment. Tremco Spectrem 2 is Greenguard Gold certification which ensures safety for use in the most sensitive indoor environments including hospitals and schools.
