one. Adhesive Energy
Glance for top-tack adhesive that bonds right away and forever. Some tapes use acrylic adhesive for extensive-Long lasting keep in Serious temperatures.
two. Temperature Vary
Choose a tape with a broad functioning temperature array, specifically for HVAC or industrial use. Some tapes purpose in ranges from -20°File to three hundred°F or greater.
3. Thickness
Thicker tape typically signifies far more longevity and better functionality in sealing and heat resistance. Nonetheless, it might be harder to apply about tight corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification guarantees the tape satisfies fireplace and basic safety requirements.
five. Dampness & UV Resistance
Ensure the tape is suitable for outdoor use if needed. UV and dampness resistance will reduce degradation after some time.
How to Apply Foil Tape The right way
