Technical requirements of aluminium bitumen flashing tape

With the continuous development of science and technology, many waterproof sealing materials have been developed. Aluminum bitumen flashing tape, as one of the many waterproof sealing materials, has played an important role in recent years. So what should be paid attention to when using aluminum bitumen flashing tape ?

Aluminum bitumen flashing tape determines the appearance and service life of insulating glass. The coating of aluminum bitumen flashing tape is a step and a key link in the manufacture of insulating glass. It determines the comprehensive quality performance of insulating glass products (whether it meets the national standards of insulating glass Five indicators), the non-drying sealant composed of butyl rubber and a small amount of polyisobutylene will not dry out in the manufacture of insulating glass. It can be mechanically coated and is suitable for assembly line use. After coating, the glue layer is not dry. Dry to maintain viscosity, at the same time have excellent heat and water resistance, will not flow under the sun and rain.
Together with the second sealant to form an excellent anti-moisture system, in order to ensure the appearance and quality of the hollow glass, the aluminum bitumen flashing tape used has the following technical requirements:
1. Must choose suitable and guaranteed aluminum bitumen flashing tape products.
2. It has good initial viscosity and adhesion to glass.
3. It has good sealing performance.
4. The coating must be uniform and the coating cross-section must be consistent.
In short, when using aluminum bitumen flashing tape for waterproof sealing, we should strictly follow the instructions for waterproofing and sealing of butyl tape to ensure that aluminum bitumen flashing tape performs well.
