Polyaspartic polyurea is a high-performance polyurethane coating known not only for its exceptional wear resistance and impact resistance but also for its superior adhesion and flexibility. These characteristics make it an ideal choice for applications in aerospace, automotive manufacturing, construction, and other fields. its relatively weak water resistance and chemical corrosion resistance limit its use in harsh environments.

To address these limitations, scientists proposed incorporating silicon modification into polyaspartic polyurea. Silicon, with its unique physical and chemical properties, can significantly enhance corrosion resistance, water resistance, and thermal stability. By introducing silicon elements into polyaspartic polyurea, a novel modified resin—polyaspartic polyurea silicon-modified resin—has been developed.
