                                     Single-component Polyurethane Roof Waterproof Coating

1.  Product Features:
1.) It is safe and environment-friendly product without solvent or pollutants. And it has approved tests by state related testing bodies so it is applicable directly to dinking waterproof works.
2.) As mono-component product, it is easier to handle. And coating application is simple.
3.) Compose of pure polyurethane, the coating film is featured with rubber's properties. High-elasticity, high-strength, high-extensibility and high adhesion.
4.) It is applicable to heavy-film coating, and the film has high compatibility without pinholes  or bubbles.
5.) The film is generated by chemical reaction,  featured with  water-resistance, corrosion resistance, fungus resistance.
6.) It is featured with  good physical and mechanical properties ,high resilience, anti-fatigue, aging resistance. Its tensile strength reaches as high as 3Mpa with elongation at break 600%. 
7.) Good weather ability makes it adaptable to drastic changes of weather regardless of hot or cold.
8.) Water-curing Mechanism make the scope of its application wider.
  
2. Construction Points
1.) Base-treatment:it is required to be firm, leveled, clean, and dry.
2.) partial treatment: internal and external corners should be shaped arch, the joints between pipes, walls and plates should be filled with this product. If necessary, non-woven fabric or fiberglass mesh fabric should be added to these joints. After this, coating-application of large-area can be carried out.
3.) Application of coating:  coat the base several times(2-3times suggested),the direction coating of different times should be perpendicular. Another time of coating should be not carried out until the previous coating is too dry to stick to hands.
4.) Vertical-face Treatment of walls :after painting the last time of coating, sand should be scattered before it is solidified.
5.) Construction of external layer: after the coating is solidified completely(about 48 hours), conduct the construction of external layer.
6.) Suggested Quantity: Film Thickness:1MM,  Coating Dosage:1.2-1.25kg/sqm.

3. Scope of Application
1.) Its applicable to waterproof and moisture works of roofing, external walls, basements, balconies ,kitchens and lavatories .
2.) it is suitable for special buildings like granaries, civil air defense works, bridge projects.
3.) It is specially suitable for waterproof construction for place where the shape is complex and pipeline bend place.
