The place is widely used.
❖Water-based polyurethane floor
It is a new environmentally friendly flooring material with water as the dispersion medium. It has the advantages of epoxy flooring and overcomes its limitations. The addition of functional fillers makes it ideal for hardness, durability and abrasion resistance.
