WJG-862 polymer modified asphalt waterproof coating (PB) for bridges and roads is a new type of environmentally friendly waterproof coating made from petroleum asphalt as the base material and a variety of high-quality polymer composite modifiers according to a scientific formula. This coating has excellent heat resistance, bonding properties, and shear resistance. It also has good affinity with petroleum asphalt products and can fully meet the special requirements of asphalt concrete bridge deck waterproofing. The waterproof performance is durable and reliable, preventing water seepage from causing structural damage, steel corrosion, and concrete carbonation, thus extending the service life of the bridge. It is a special coating for waterproofing various bridges and elevated roads.
Product Classification
Products are classified into types Ⅰ and Ⅱ according to their performance.
Product Features
◆ This product is a water-based waterproof coating that is non-toxic, odorless, and environmentally friendly. It is cold-applied, with simple construction methods; both spraying and brushing are possible. It ensures construction quality on various irregular surface layers, with low material and construction costs, and has good social and economic benefits.
◆ This product has the characteristics of high-temperature anti-sagging, low-temperature anti-cracking, strong affinity with asphalt concrete and cement concrete, high shear resistance, and fatigue resistance. Due to the use of professional American spraying equipment and the mechanical spraying function that works simultaneously with the spraying material, incorporating Bonnivie fiber to reinforce the mixture in a three-dimensional manner, greatly improving the cohesive force, it has anti-rutting, anti-fatigue, anti-aging properties, improves the flexibility of the waterproof layer, anti-peeling, wear resistance, prevents corrosion of bridge structures, reduces bridge maintenance costs, and extends the service life of bridges and roads.
◆ Good impermeability and airtightness, strong resistance to base deformation.
◆ High elasticity, aging resistance, corrosion resistance, long life, can form a seamless waterproof membrane.
◆ Cold construction, fast surface drying, simple construction, easy operation, safe, and pollution-free.
◆ Wide temperature adaptability. During bridge deck construction, it does not sag at high temperatures of 140℃ and does not crack at low temperatures of -25℃.
◆ The construction material cures and forms a film quickly, and the film has good toughness. Due to the addition of chemical auxiliaries to the material, the material can form a film in a short time, shortening the bridge deck waterproofing construction time.
◆ Strong bonding force and good overall waterproof performance. This product is a high-polymer asphalt-based coating material. Auxiliary materials are added to the formula to improve the penetration and bonding force of the coating. The waterproof layer has a strong penetration effect on the base layer and a bonding effect on the upper layer material. The waterproof layer does not become brittle when cold and does not deform when hot, resulting in good overall waterproof performance.
◆ After construction, the shear strength reaches 1~1.5Mpa, and the crack resistance is that when the base layer cracks 2mm, the coating has no cracks.
◆ Water-based cold-applied coating, non-toxic and odorless, can be applied on slightly damp substrates.
◆ The coating is tough and highly elastic, with excellent water resistance and weather resistance.
◆ It does not sag during construction on vertical and sloped surfaces.
Application Scope
