Spectrem 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.
Spectrem 1 meets or exceeds the requirements of the following specifications:
• ASTMC920TypeS,GradeNS,Class100/50,UseNT,M,G,AandO • ASTMC1248
• CAN/CGSB 19.13-M87, MCG-2-40-B-N
meeting ASTM E2357, the Standard Test Method for Determining Air Leakage of Air Barrier Assemblies, and NFPA 285, the Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non- Load-Bearing Wall Assemblies Containing Combustible Components.
Closed-cellpolyethylenebackerrodsortheTremcosealanttapeillmod®600 is preferred as joint backing to control depth of sealant bead. Where depth of joint will prevent use of joint backing, an adhesive-backed polyethylene tape should be installed to prevent three-sided adhesion. Joint backing mustbe dry at time of the sealant application.
Surface must be sound, clean, and dry. Contact surfaces should be free of loose dirt, dust, oils, and any other contaminants. Tremco recommends that air temperatures be 40 °F (5 °C) or above before applying any sealant.
Spectrem 1 is easy to apply with conventional caulking equipment. Fill joint completely and tool. At 75 ˚F (23.9 ˚C), 50% RH, a durable skin will form within 10 to 30 min. Please visit www.tremcosealants.com for complete application instructions.
May be used in any joint designed in accordance with accepted architectural/engineering practices. Joint width should be 4 times anticipated movement, but not less than 1/4″ (6 mm) wide.
