More Information
Summary:Provided is a waterborne polyurethane obtained by polymerizing an alicyclic polyester polyol, a diisocyanate, and a hydrophilic chain extender. The alicyclic polyester polyol includes an alicyclic polyester polyol having a four-membered ring and/or an alicyclic polyester polyol having a six-membered ring. Based on a usage amount of 1 part by weight of the alicyclic polyester polyol having a four-membered ring and/or a six-membered ring, a usage amount of the diisocyanate is between 0.3 parts by weight and 12 parts by weight, and a usage amount of the hydrophilic chain extender is between 0.05 parts by weight and 1.5 parts by weight.
