%X The developed crack - surface sealing polyurea material was tested based on GB/T 18244 - 2022 and GB/T 16777 - 2008. Tests included surface drying time, tensile strength, elongation at break, bond strength with concrete, and tensile properties after UV aging. The material met or surpassed technical requirements, with tensile strength and elongation at break reaching 15.3MPa and 257% even after 2000h of UV aging.
