Spectrem 1

PRODUCT DESCRIPTION

Spectrem® 1 is a high-performance, single-component, moisture-cure, ultra-low modulus silicone sealant ideal for sealing difficult-to- adhere-to substrates in a variety of applications. 

BASIC USES

Spectrem 1 is the ideal sealant for the most demanding dynamically moving joints. This includes material having a high coefficient of linear expansion such as aluminum curtainwalls, precast concrete panels, metal panels, and window perimeters.

When detailing over the ExoAir® Air Barrier system, Spectrem 1 is the recommended sealant to ensure an airtight seal throughout the building envelope. Spectrem 1 has excellent adhesion to most polyethylene-backed, self-adhering air barrier membranes. The performance of Spectrem 1 is exceptional when used on the polyethylene face of ExoAir 110, Exoair 110AT, ExoAir TWF and the cured surface of Exoair 130, and ExoAir 230.

Spectrem 1 is recommended for use with Tremco's Silicone Rubber extrusions, Spectrem Simple Seal and Tremco's patented solution, Proglaze® ETA (Engineered Transition Assembly), for sealing between challenging conditions such as the opaque wall air barrier and window/curtain wall assemblies. Spectrem 1 is also compatible for use over Nudura Insulated Concrete Forms (ICF).

FEATURES & BENEFITS 

Spectrem 1 is a perfect choice for sealing difficult-to-adhere-to substrates. Spectrem 1 has excellent adhesion to a variety of substrates, allowing for one product that can be used for multiple applications on the same job, from perimeter caulking to expansion joints. The ultra-low modulus of Spectrem 1 means high elasticity with movement accomodation of +100/-50%.

• Slightly grainy texture allows Spectrem 1 to zipper rather than fully tear if failure occurs

• Offered in a wide variety of colors, with custom colors and color matching available for special projects

  There is no mixing required with Spectrem 1, so product is always ready to use for immediate application with conventional caulking equipment. Spectrem 1 provides resistance to driving rain, ozone, ultra-violet light and temperature extremes, plus safeguards against water penetration with exceptional weatherability in all climate zones. Additionally, the Greenguard Gold certification on Spectrem 1 ensures safety for use in the most sensitive indoor environments including hospitals and schools.

  Spectrem 1 meets or exceeds the requirements of the following specifications:

• ASTM C920 Type S, Grade NS, Class 100/50, Use NT, M, G, A, and O
