Shurtape AF 984CT – Cold-Temperature FSK Tape for Insulation Seams

Shurtape AF 984CT is a high-performance foil-scrim-kraft (FSK) tape engineered for sealing and seaming FSK-faced fiberglass insulation systems in cold-temperature environments. Its specialized acrylic adhesive provides consistent performance across a wide thermal range, making it suitable for both commercial and industrial HVAC applications.

Application Features

• Cold Weather Adhesion: Maintains bond strength from -20°F to 260°F for dependable sealing in sub-zero environments.
• FSK Backing Construction: Comprised of aluminum foil, reinforced scrim, and kraft paper for dimensional stability and strength.
• Moisture and Vapor Barrier: Helps minimize energy loss and resist odor, smoke, and moisture transmission through insulation seams.
• Smooth Finish: Designed for wrinkle-free application and visual continuity on faced duct or pipe insulation.

Technical Specifications

• Backing: Foil/Scrim/Kraft laminate
• Adhesive: Cold-temperature acrylic
• Total Thickness: 11.1 mils
• Adhesion to Steel: 64 oz/in
• Tensile Strength: 34 lb/in
• Temperature Range: -20°F to 260°F
• Width: 3 inches (76 mm)
• Length: 150 ft (46 m)
• Shelf Life: 24 months (stored under recommended conditions)

Installation Guidance

• Clean and dry surfaces before tape application to ensure optimal adhesion.
• Apply pressure uniformly along the tape to maximize surface contact.
• Use in conjunction with FSK-faced board or blanket insulation per project spec.

For HVAC and Mechanical Insulation Contractors

AF 984CT is engineered to meet demanding field conditions found in mechanical rooms, chilled water lines, or ductwork exposed to variable temperatures. It complies with industry standards for vapor-retarder performance in foil-faced insulation systems and is suited for both initial installation and system repairs.

Performance Highlights

• Stable across a broad temperature range without adhesive degradation or delamination.
• Long-lasting seal for thermal insulation systems in commercial HVAC and mechanical applications.
• Low water vapor transmission rate for moisture-critical environments.

Shurtape AF 984CT is a reliable choice for sealing insulation systems requiring durable adhesion and consistent performance in cold weather. Designed for professionals, it supports energy efficiency and compliance in modern mechanical insulation assemblies.
