The single component polyurethane our factory produces is made up of polyether and thinner. We employ advanced recipe and technology controlling the rate of polyether and thinner best. Considering the end capped effects of thinner, at the same time, we enhance the molecular weight of the polymer, which is due to the quality. The single component polyurethane is easy to use, because of avoiding to mixing. In addition, the film of single component polyurethane is the product of the action reaction of the polyurethane and the water/ vapor in the execution place.
