Name      Special High-speed Rail High-performance Spray Polyurea Waterproofing Coating
Model     HT-1001GT
Description  The coating system consists of amine-terminated polyethers, amine chain extender and MDI prepolymer, belongs to spraying quick cured polyurea and has high elasticity, high elongation and high strength.
Applications   It is applied to overall spraying for protection of precast concrete bridges of passenger rail lines (at the speed of over 200km/h), ballast-free high-speed railways, intercity rails and city light rails, waterproofness of viaduct bridge pavement concrete bridge deck, anti-collision walls and cable trenches, protection of viaduct bridge concrete bridge pier bearing support and high standard waterproofing engineering of high-speed rails, tunnels and nuclear facilities.
