Advantages of Polyurethane Products

 

Environmental protection: water is used as the dispersion medium, no pollution, no solvent odor, no environmental pollution, low VOC content, in line with the requirements of environmental protection regulations; super adhesion: water-based polyurethane has very strong adhesion, and can even be attached to Surface of glass products.

 

High hardness: water-based polyurethane coated floor has high hardness, the ordinary type (1:9) has a hardness of 1.5-2.0H; the reinforced type (1:5) can reach 3-4H; the heavy-duty type (1:2) can reach 5-6H, wear resistance and scratch resistance are better than epoxy floor paint.

 

Good flexibility: Water-based polyurethane-encapsulated floor paint with certain flexibility can not only provide excellent mechanical properties such as crack bridging and impact resistance, but also have better protection for concrete, and also have the characteristics of sound attenuation and flexible foot feeling. Walking on the floor, the foot feels relatively comfortable, and the echo of the ground is small, so it can be used in offices, conference rooms, classrooms, hospitals and other places that require high silence.

 

 One-sided air permeability: Water-based polyurethane encapsulation undergoes two reactions during the curing process, one is a complex chemical cross-linking reaction and the other is the process of volatilization of water as a solvent. During the volatilization process of water molecules, micron-sized pores are left , just like human skin, when the seasons change or the temperature rises, the internal water vapor can be discharged through the capillary pores, but the external moisture is not easy to penetrate into it.
