Water based polyurethane is a new kind of polyurethane system which use water instead of organic solvent as polyurethane dispersion medium.Waterborne polyurethane with water as solvent, has no smell, no pollution, easy to scrub, fire and explosion proof, safe and reliable, excellent mechanical properties.Waterborne polyurethane has a very high adhesion to the substrate, the curing coating has a very high corrosion resistance, excellent chemical resistance, low film shrinkage, high hardness, good wear resistance, excellent electrical performance, with a very high physical and chemical resistance.Airtight characteristics at the same time, it overcomes the paint, provide a more durable service life and protection function, with water as dispersion medium, resource conservation, no pollution, accord with environmental protection requirement, relative to the waterborne epoxy floor coatings, waterborne polyurethane has a higher strength, flexibility, adhesion, thus in the floor industry more and more important status in the family, experts believe that in today's environmental protection, waterborne polyurethane prospect is very broad, so far in large industrial workshop, computer room, warehouse, underground parking, laboratory, wards, operating room, workshop in areas such as a large number of areas.

The performance characteristics ：
1.High hardness, strong scratch resistance.Due to the excellent flexibility of waterborne polyurethane, it can cushion and protect itself when there is a hard scratch, so the ground is not easily marked.
2.No solvent, no smell, no pollution, no poison.With water as the dispersion medium, no pollution, no smell of solvent, no environmental pollution, low VOC content, in line with the requirements of environmental laws and regulations.
3.Super adhesion.Waterborne polyurethane has very strong adhesion and can even be attached to glass surfaces
4.Excellent acid, alkali and chemical resistance.
5.Good flexibility.Waterborne polyurethane floor paint with certain flexibility can provide excellent mechanical properties such as crack bridging, impact resistance and better protection against concrete.
6.Wear resistance, pressure resistance, high temperature resistance, resistance to yellow, waterproof moistureproof, fire and other comprehensive performance is the best.
