High-speed rail dedicated high-performance spray polyurethane waterproof coating
| Product Name | High-performance Spray Polyurea Waterproof Coating for High-speed Rail |
| Model Number | HT-1001GT |
| Product Description | The coating system is composed of end-amine polyether, amine chain extender, and MDI prepolymer. It is a spray-type, fast-curing polyurea variety with high elasticity, high elongation, and high strength. |
| Main Applications | Used for overall spraying of prefabricated concrete bridge protection on high-speed passenger dedicated lines (speeds above 200km/h), intercity railways, and urban light rails. Waterproofing of elevated road surface concrete bridge decks, crash barriers, and cable trenches, and protection of elevated bridge concrete piers and foundations. Waterproofing projects with high standards such as high-speed railways, tunnels, and nuclear facilities. |
