PRODUCING METHOD OF WATER-BASED POLYURETHANE, WATER-BASED POLYURETHANE THEREBY AND PRODUCING METHOD OF PRODUCT USING WATER-BASED POLYURETHANE

摘要

A method of preparing waterborne polyurethane with an enhanced characteristic of separating polyurethane from water by enabling waterborne polyurethane particle behavior to be adjusted in a waterborne polyurethane processing procedure involving absorption of water into a target material, for producing a product with a polyurethane membrane on its surface, a waterborne polyurethane composition prepared by the method, and a method of producing a product using the composition are provided.
