Hebei Ruide polyurethane waterproof coating
Polyurethane waterproof coating is a high-performance waterproof coating with excellent waterproofing and weather resistance. It is widely used for waterproofing buildings, bridges, tunnels, and other projects. Its key features include strong water resistance for long-term waterproofing; excellent wear resistance, good weather resistance, and resistance to aging; easy application and rapid drying, quickly forming a complete waterproof layer.
Product Characteristic
●The product is easy to construct. After the product is cured, it will form a seamless and complete elastic waterproof layer, which improves the waterproof and anti-seepage ability of construction projects. In particular, it has high strength and extensibility, and has strong adaptability to the cracking or expansion and contraction of the base layer.
●It is convenient for maintenance. Only local repair of the damaged part is needed to achieve the original waterproof effect, which saves time and labor and incurs low costs. The color can be adjusted to meet your color requirements.
Application Scope
It is applicable to national key projects and general waterproof projects, such as roofing, color steel tiles, basements, civil air defense projects, kitchens and bathrooms, culverts, tunnels, bridges, water pools and other projects.
Matters Needing Attention
During application, it is recommended to first clean and prepare the surface to be coated, ensuring it is flat, dry, dust-free, and oil-free to ensure proper adhesion and waterproofing. Secondly, the coating should be applied evenly to the surface and thoroughly dried after application to ensure a stable waterproof layer.
Packaging, Storage and Transprotation
●Packaging: Single component: in 25kg barrels; Double components (with a ratio of 1:2): 60kg per set.
●Storage: Store the materials in a place where the temperature ranges from 0℃ to 40℃. Keep them away from fire sources and avoid direct sunlight for a long time.
●During transportation, strictly prevent exposure to sunlight and rain, avoid collisions, and pay attention to fire prevention.
●The storage period of the product is six months.
