Tremco Spectrem 1 Gray 10oz Cartridge
Tremco Spectrem 1 Gray is a high-performance, single-component, moisture-cure silicone sealant designed for difficult-to-adhere substrates and demanding dynamic joints. Its ultra-low modulus formula provides excellent elasticity and movement accommodation for curtainwalls, precast panels, metal panels, and window perimeters. Spectrem 1 also offers exceptional weatherability, resistance to driving rain and UV exposure, and strong adhesion across a wide range of building envelope applications.
Key Features
- Single-component, moisture-cure, ultra-low modulus silicone sealant.
- Movement capability of +100% / -50% for demanding dynamic joints.
- Excellent adhesion to difficult-to-adhere substrates.
- Resists driving rain, ozone, ultraviolet light, and temperature extremes.
- No mixing required and ready to use with conventional caulking equipment.
- Slightly grainy texture helps the sealant zipper rather than fully tear if failure occurs.
- GREENGUARD Gold certified for sensitive indoor environments.
- Compatible with Tremco silicone rubber extrusions, Spectrem Simple Seal, and Proglaze ETA systems.
Applications
- Aluminum curtainwalls.
- Precast concrete panels.
- Metal panels.
- Window perimeter sealing.
- Expansion joints.
- Building envelope air seal detailing over ExoAir air barrier systems.
- Transitions between opaque wall air barriers and window or curtain wall assemblies.
- Projects using difficult-to-adhere substrates.
