one. Adhesive Power
Search for prime-tack adhesive that bonds immediately and forever. Some tapes use acrylic adhesive for extended-Long lasting hold in Intense temperatures.
2. Temperature Range
Choose a tape with a broad functioning temperature array, specifically for HVAC or industrial use. Some tapes operate in ranges from -20°File to three hundred°F or greater.
3. Thickness
Thicker tape normally suggests far more durability and superior efficiency in sealing and warmth resistance. Having said that, it could be harder to use all over restricted corners.
four. UL Certification
For HVAC use, UL181A-P or UL181B-FX certification guarantees the tape satisfies hearth and foil tape safety standards.
five. Humidity & UV Resistance
Make sure the tape is well suited for outdoor use if desired. UV and moisture resistance will avert degradation with time.
How to Apply Foil Tape The right way
Making use of foil tape is straightforward, but some greatest practices guarantee optimum general performance:
Clear the Surface: Take away any Dust, oil, or dampness right before applying the tape.
Evaluate & Cut: Pre-measure the duration you have to prevent squander.
Press Firmly: Make use of a squeegee or push tool to bond the tape securely for the floor.
Overlap Edges: For ducts or seams, a bit overlap Every single section for a good seal.
Prevent Stretching: Stretching foil tape can weaken the adhesive and compromise overall performance.
