Abstract: A solvent-free, rigid and self-leveling bio-polyurethane(component A)is prepared by bio-based branched polyester/polyether polyol and then is mixed with polymeric MDI curing agent (component B )at a ratio of 3: 1-4: 1. This floor coating can be cured rapidly and has high chemical stability and hardness and good acid and alkaline resistance, espe-cially excellent resistance to 10% H, S0,. The coating meets the requirements of environmental friendly coatings and hardly pollutes construction environment, which enable it to have a good application potential.
