[China Aluminum Industry Network] Metal foil self-adhesive waterproof membrane surface using metal aluminum foil (soft metal film) as the surface layer, metal foil with moisture, airtight, heat insulation, resistance to solar ultraviolet light, abrasion resistance and other characteristics. The self-adhesive layer is an anti-aging butyl rubber with strong adhesion.
Metal foil self-adhesive waterproof membrane features:
1. The solar radiation absorption rate (solar radiation absorption coefficient) is very low (0.07). It has excellent thermal insulation properties and can reflect more than 93% of radiant heat.
2, the construction is simple, cold construction, without too much professional construction, remove the material under the insulation film, sticky position can be.
3, the self-extension rate of 400 - 1000%, the thermal expansion and contraction of the metal roof has a strong adaptability. With the convexity and depression of the roof and stick the roof, so that the air and metal roof completely isolated, both to achieve waterproof The function can also play an anti-corrosion effect, greatly prolonging the service life of the color board roof.
4, special strong adhesion, ordinary knife wounds, can be self-healing at room temperature.
5, good durability, artificial aging for twenty-five years.
6, good tensile strength, good flexibility, can paste all kinds of irregular roof.
Metal foil self-adhesive waterproofing membrane application:
Widely used in new and old color steel housing surface for waterproofing.
