As the amino groups are provided with the steric hindrance groups, the ultraviolet aging resistance of the polyaspartate coating is obviously superior to that of the common polyurea coating, and the high-density amino groups correspondingly generate high-density urea bond groups, so that the mechanical property, the high temperature resistance and the salt spray corrosion resistance of the polyaspartate coating are also higher than those of the common polyurea coating. The polyaspartic acid ester belongs to a secondary amino compound, and the activity of active hydrogen of the polyaspartic acid ester is further inhibited by a steric hindrance group, so that the gel curing time of the whole composite system and isocyanate reaction can meet different requirements of mechanical spraying, manual brushing and the like in actual construction through the compound use of different structures.
