This product is a hot-melt asphalt waterproof coating with high solid content. It has the characteristics of not solidifying after long-term contact with air and always maintaining viscous colloid; it has strong self-healing ability, sticks to touch and is difficult to peel off, and still maintains excellent bonding performance at -25℃; it can effectively solve the cracking of the waterproof layer caused by stress transfer of cracking of the base layer, fatigue damage or premature aging under high stress state ; the viscosity of its creep material can well seal the capillaries and cracks of the base layer, solving the problem of water leakage in the waterproof layer; at the same time, it can improve the compatibility problem of waterproof membrane and coating when used in combination. Various construction methods such as hot scraping and hot grouting can be used.
YN-C907 Lidun non-curing rubber asphalt waterproof coating
Implementation standard：JC/T 2428-2017
- Product Features
- Creep performance: It can effectively absorb the stress of the base layer and deform instantly under the action of external force, which not only protects the waterproof layer from damage, but also improves the waterproof reliability and prolongs the service life;
- Construction performance: The film is formed quickly without maintenance, and the subsequent processes can be carried out immediately after construction; it has strong affinity for various substrates, can form a stable waterproof coating, and has low requirements for the flatness of the base layer, eliminating the step of brushing the base treatment agent;
- Adhesion performance: It has instant adhesion characteristics, is difficult to peel off, and can effectively fill the deformation cracks of the base layer;
- Temperature adaptability: high temperature resistance up to 60~70℃, while still maintaining excellent flexibility at -25℃ low temperature environment;
- Self-healing: When the waterproof layer is damaged, the damage point will not spread and water leakage will not occur. The material can gradually achieve self-repair through creep, significantly improving the waterproof reliability.
- Environmental performance: No organic solvent added, solid content exceeds 99%, no smoke or odor during the entire construction process;
- Extension performance: The elongation rate exceeds 1000%, and the elongation reaches more than 60mm. It can adapt to the displacement of the base layer without damaging the waterproof layer, ensuring the long-term sealing and waterproofing of the building structure;
- Chemical corrosion resistance and aging resistance: After acid, alkali and salt medium immersion test and heat aging treatment, the performance retention rate is above 90%
