| Abstract: | For preparing the polyurethane waterproof coating that is high tensile break strength and breaking elongation ratio,we used EP330-N and MOCA as the composition curing agent.When the content of HVGO and calcium carbonate are 30.0% and 15.0%,respectively,and the MOCA/EP330-N is 0.90/0.10,we can prepare the high tensile break strength and the breaking elongation PU waterproof coating,and the curing time is about 2.1h at room temperature.The dank of sample is satisfied of GB request. |
