External Waterproofing Membrane

Introduction

External waterproofing membrane, also known as butyl waterproofing tape, is a material used for waterproofing the external surface of various structures such as roofs and foundation walls. This material is designed to stay flexible for extended periods and offers high resistance to UV radiation, temperature changes, and mechanical stress.

Feature

The Waterproof Butyl Rubber Aluminium Tape have the properties of waterproof sealing and chemical resistance, and they are also UV resistant, as well as having a long service life. Secondly, our product has good adhesive ability even at low temperature. Finally, it has high elongation ability, does not stick to your hands during installation, and has the characteristics of environmental protection and transparency.

Application

1：The overlapping between the steel roof color steel plates and the lighting panels, and the sealing of the connection of the falling gutter.

2：Doors, windows, concrete roofs, and ventilation ducts are sealed and waterproof.

3：Installation of PC board and endurance board.

4：The waterproof film of automobile doors and windows is pasted and sealed to resist shock.

Production Process

The manufacturing process for the butyl waterproofing tape involves three primary steps. The first step is the preparation of the butyl rubber compound, which involves blending butyl rubber with various fillers, stabilizers, and adhesives. The second step is the extrusion process, which involves passing the rubber compound through an extrusion machine to form continuous strips of tape. The final step is the curing process, which involves exposing the tape to a controlled temperature environment to promote the cross-linking of the rubber compound, leading to improved strength and durability.

Construction Conditions

The external waterproofing membrane is best applied during dry weather conditions. The surface to be waterproofed should be free of dirt, debris, and other contaminants to ensure proper adhesion. The application temperature of the tape should be between 5°C and 40°C, and ambient humidity should be below 80%. Additionally, the surface should be primed with an appropriate primer before application to ensure proper adhesion.
