Substructure of High-speed Rail coating  polyurea waterproofing systems

                                                              

Descriptions              

Recent years high-speed rail projects developed fast, with the speed promotion of the train, the firmness and durability of the substructure became increasingly important, it’s fairly necessary to select a fine protective material. SWD9009 has high performance of waterproof, anticorrosion and anti-aging, successfully applied in domestic high-speed rail projects.

                                                                                

Characteristics            

The product has high reactivity, could spray-applied forming on curved,slope and vertical surface without sagging. Dense and seamless coating integrates with the substrate by strong adhesion. Good tensile strength and flexibility of the coating can adapt to the slight deformation of concrete by shock, cracking and displacement. High performance of anti-aging, no cracking, no peeling, no powdering, weather resistant.
