1. Adhesive Toughness
Search for prime-tack adhesive that bonds promptly and completely. Some tapes use acrylic adhesive for extended-Long lasting maintain in Serious temperatures.
two. Temperature Range
Pick a tape with a large working temperature selection, specifically for HVAC or industrial use. Some tapes perform in ranges from -twenty°F to 300°File or increased.
three. Thickness
Thicker tape frequently means extra durability and much better efficiency in sealing and heat resistance. Nonetheless, it might be more durable to apply around tight corners.
4. UL Certification
For HVAC use, UL181A-P or UL181B-Forex certification ensures the tape meets fire and basic safety specifications.
five. Dampness & UV Resistance
Make sure the tape is ideal for outside use if required. UV and humidity resistance will avert degradation as time passes.
How to use Foil Tape The right way
Making use of foil tape is easy, but a number of greatest practices assure highest overall performance:
Clean up the Surface area: Eliminate any Filth, oil, or humidity ahead of implementing the tape.
Measure & Slash: Pre-measure the length you'll want to steer clear of waste.
Press Firmly: Utilize a squeegee or press Instrument to bond the tape securely into the area.
Overlap Edges: For ducts or seams, slightly overlap each section for a decent seal.
Steer clear of Stretching: Stretching foil tape can weaken the adhesive and compromise general performance.
