1. Introduction of the Product
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.
