1. Product Overview:

I developed the production of two-component reaction curing type urethane waterproof coating synthetic polymer is a high performance green waterproof coating. Where, A component is a group with-NCO prepolymers of polyether, B component is a surfactant, filler, curing agent and catalyst containing-OH groups viscous fluid. When used, the A, B by a certain weight ratio of two components mixed to form after a few hours later both elastic solid, the overall durability of tough waterproof coating another layer. This product is suitable for railway bridge deck waterproofing, prevent leakage of the concrete bridge deck caused by steel corrosion, improve the life of the bridge, the performance index test by the railway construction inspection station, the test items meet the technical requirements of national standards.
