ALU-PET TAPE (40 µm) THIN MICROPERFORATED
The Ultimate Solution for Waterproofing and Ventilation
The anti-drip aluminum tape with small microperforation is an innovative material designed for sealing, waterproofing, and ventilation, offering effective protection against moisture and condensation in various applications. Thanks to its microperforated design, it allows air to escape while blocking water entry, making it an ideal solution for a wide range of industries, including construction, HVAC, and automotive.
COMPOSITION

Support (A): Aluminum laminated with PET (closed with PET TNT).
Adhesive type (B): Acrylic
Liner (C): Siliconized paper
KEY FEATURES

Material: Aluminum sheet with fine perforations.
Adhesive: Moisture-resistant and heat-resistant.
Waterproofing: Prevents leaks and water infiltration.
Transpirabilidad: Permite la salida de vapor para prevenir
condensaciones.
Thermal resistance: Withstands extreme temperatures.
ADVANTAGES AND DISADVANTAGES OF ANTI-DRIP ALUMINIUM TAPE
✅ Advantages:
- Prevents condensation: Thanks to its microperforations, it avoids moisture accumulation on sealed surfaces.
- Highly durable: The aluminum sheet withstands UV exposure, rain, heat, and extreme cold.
- Easy to apply: It can be cut and shaped easily, making it convenient for professionals and DIY users.
- Versatile applications: Suitable for construction, HVAC ducts, roofing, and automotive insulation.
- Long-lasting performance: Does not degrade over time and maintains strong adhesion.
⚠ Disadvantages:
- Not ideal for applications requiring completely airtight sealing.
- May not adhere well to rough or highly uneven surfaces if not applied correctly.
- Requires a clean, dry surface for optimal adhesion.
