Waterproof Membrane
1) Waterproof of skin type
2) Self-adhered modified asphalt compund
3) Water-self-locking
Features:
1 Its good physical properties like thermal resistance,low-termperature-flexibility meet the waterproof requirements in various environments
2 Its good weather-resistance meet the requirement in anti-aging
3 The Specially developed membrane is with super properties of high-strength, aging-resistance,reflection and heat insulation, which can well resist to unfavorable conditions
4 Its Chemical stability, anti-aging property are improved dramatically by adopting world advanced anti-aging-treatment technology and adding additives like antioxidants, ultraviolet absorber into the product
