Product introduction
This product is a kind of reacting-cured polymer waterproof coating, which is prepared by using polyether polyol and isocyanate as the main raw materials, mixed with various additives such as potentiating agent, and prepared by special process through high temperature dehydration and polymerization. When used, it is coated on the waterproof base, and chemical reaction is carried out based on the moisture in the air through the -NCO end of the prepolymer. Form a soft, jointless rubber-like waterproof film on the base surface.

Product characteristics
Products, convenient construction, wide range of application, complex parts of the construction has obvious advantages.
?
After curing, a jointless, complete elastic waterproof layer is formed, which improves the waterproof and impermeability of construction projects, which is impossible to achieve by coil products.
?
The film has high strength and extensibility, strong adaptability to the cracking or expansion of the base layer.
?
Maintenance is simple, only partial maintenance of damaged parts, can still achieve the original waterproof effect.
?
Construction precautions
The base is required to be smooth, strong, not sand, and the depression is levelled with mortar.
?
Stir well before use, the precipitation in the barrel is a normal phenomenon, and can be used after stirring well.
?
When brushing, pour the mixed material on the base, spread it evenly with the scraper, each coating should be below 0.5 mm, and decide the number of construction passes according to the requirements.
?
Asphalt solvent-based paint each brush thickness must be controlled within 0.5 mm, otherwise the surface film after the following solvent volatilize slowly, there will be sticky hand phenomenon, in this case, you can sprinkle a layer of powder on the surface, wipe and then carry out the next construction.
