Abstract：The green solvent-free single polyurethane waterproofing coating was prepared through adjustment of formulation process with low viscosity environmental protection vegetable ester，instead of volatile petroleum solvent. The effects of environmental vegetable ester content on VOC content，drying time，viscosity and tensile properties were discussed.
