Aluminum Foil Tape AF4525

(High Quality Thermal Insulation Tapes)

Introductions on Aluminum Foil Tape AF4525:
Aluminium foil tape AF4525 is composed of 45 micron/1.8 mil aluminum foil backing with high tensile strength, solvent acrylic adhesive with high performance and silicon release paper which is easy to release.

Features of Aluminum Foil Tape AF4525:
1. Aluminium backing enable BondTape industrial adhesive tapes have good heat and light reflection performance;
2. Durable sealing and bonding for HVAC ducts, etc. for the high quality adhesive;
3. Good aging resistance both indoors and outdoors.
4. Features with good sealing and repairing performance for its low water vapor transmission rate.

Typical Applications:
Extensively used in HVACR industry to joint and seal the joints and seams of/between fiberglass blankets, fiberglass duct boards and ventilation ducts, etc.
General purpose patching and sealing, etc. are all possible.

Usage Instruction:
1. Suitability test is necessary if you are not sure whether BondTape AF4525 is fit for your particular application purpose and application condition.
2. Suitable pressure is needed while applying our tapes onto material surfaces for our adoption of pressure-sensitive adhesive.
3. Best application conditions: Should be applied onto clean and dry surfaces at the optimum temperature of +10 ~ +40°C; or else, the adhesion effect will be reduced.
