Product Summary of Polyurea Safety Protection Material
It is a general-purpose high-performance damping coating. It can be applied by troweling to reach the required thickness in a single pass without special construction equipment. The drying time can be adjusted via formula customization according to customer demands, and the color is fully customizable. It is widely used in rail transit, engineering machinery, ships & warships, architectural venues and many other fields.
