Products Description
SPU-311 Two Components Polyurethane Waterproof Coating is a reactive waterproof coating formed from two components’ reaction, Component A is the polyurethane pre-polymer reacted by polyether-polyol and isocyanate and component B is the liquid mixture constituted by hardener, thickener, chain-extender and filler. When use, we mix component A and B at a certain proportion. After being stirred well, it is coated on the construction base surface, then wait for hours’ reaction and curing. It forms a jointless, flexible and strong rubber waterproof layer.
● Pitch free formulation, environmental friendly.
● Good rubber elasticity and resilience, high tensile strength, strong resistance to the deformation of base layer (shrinkage and cracking).● Cured by two components’ reaction, pinhole-free, no bubbles.
● Good bonding property, strong adhesion.
● Excellent water and corrosion resistance.
● Excellent low temperature flexibility, -35 ℃ low temperature bending without cracking.

Storage&Transport
During transportation and storage, pleaseprevent sunlight or rain, keep away from fire, and avoid collision, kept in ventilated place. The best storage temperature is 5℃-25℃, the temperature is not allowed to be over 35℃.
The shelf life is 6 months under normal transport and storage conditions.
Notices
Construction temperature is about 5℃-35℃, and construction is forbidden in rainy or snowy days.
Stirring evenly the Group B component before usage, It is recommended to use electric stirring equipment (about 300r/min) to stir for 2-3 minutes, and then use rubber or metal scrapper for scraping and coating construction.The higher the temperature, the shorter the operating time.
