Product Specification：

————

The product is a waterproof membrane made of long-fiber polyester felt as the base, SBS as the main modified enamel and adding functional modifier, and modified asphalt as the coating material. The product meets the advantages of the national standard SBS elastomer modified asphalt waterproofing membrane. At the same time, it also adds anti-gas ion penetration and salt and alkali corrosion resistance. It is the first choice material for building waterproof engineering in coastal and strontium-salt areas.

PRODUCT

INTRODUCTION

FEATURES

PRODUCT

Waterproof performance, product performance meets or exceeds national standards, and has all the excellent performance of ordinary SBS elastomer waterproofing membrane.

①

It has good resistance to chloride ion penetration and is 20 times of ordinary SBS modified bitumen waterproofing membrane. It can effectively protect the main body of building structure from corrosive media.

②

Pay attention to controlling the flame during construction and heat it evenly.

Hot melt construction

Construction by hot melt method. That is, a flame spray gun is used to bake the hot melt adhesive of the bottom layer of the coil for bonding.
