Overview :

                Polyurethane waterproof coating is a single component polyurethane waterproof coating made of isocyanate, polyether and other isocyanate prepolymer by addition polymerization reaction, with catalyst, anhydrous additives, anhydrous filler, solvent and so on, by mixing and other processes.  

                This kind of coating is reaction curing type (moisture curing) coating, with high strength, high elongation, good water resistance and other characteristics.  Strong adaptability to base deformation.  Polyurethane waterproof coating is a liquid construction of one component environmental protection waterproof coating, is based on imported polyurethane prepolymer as the basic ingredient, without tar and asphalt additives.  It is the moisture in the air after contact curing, on the base surface of the formation of a strong and tough seamless integral film.  

Product features  :

1.Can be in the wet or dry various base surface directly construction.  

2. strong adhesion with the base surface, the polymer material in the film can penetrate into the base surface fine seam, strong follower.  

3. The film has good flexibility, strong adaptability to expansion or cracking of the base, and high tensile strength.  

4. Green environmental protection, non-toxic, tasteless, pollution-free environment, no harm to the human body.  

5. Good weather resistance, no flow at high temperature, no cracking at low temperature, excellent anti-aging properties, oil resistance, wear resistance, ozone resistance, acid and alkali erosion. 
 
6.the film is dense, the waterproof layer is complete, no cracks, no pinholes, no bubbles, water vapor permeability coefficient is small, both waterproof function and gas function.  

7.Simple construction, short construction period, convenient maintenance  

8. According to the need, can deploy a variety of colors  

9. Light weight, does not increase the load of the building
 
Construction requirements:  

1.  The base surface is flat, clean, no sand, loose, moisture content is less than 8%.  

2.  Construction should be carried out first base acceptance, to ensure that meet the requirements, first coated with a layer of adhesive, adhesive must be uniform.  

3.  Adhesive curing, second brushing, brushing direction and the previous vertical cross, to prevent leakage of scraping, brushing three to five times.  

4.  After completion, the waterproof layer is not solidified before, shall not people, shall not carry out the next process, so as not to destroy the waterproof layer.  

 Transport storage:

1.  This product is stored in dry, ventilated, cool place, shelf life from the date of production has not been opened for 2 years.  

2.  Transportation shall be handled as non-dangerous goods.  

3. Polyurethane waterproof coating shall be stored in a dry and ventilated warehouse for 2 years.
