AI Technical Summary
Technical Problem
The existing coating compositions have insufficient impact peeling strength of wedges under high-strength tensile and low-temperature conditions, making it difficult to meet the needs of complex application environments.
Method used
A high-performance coating is formed through contact with the substrate using a composition comprising an epoxy compound, an amine-functional aliphatic etheramine-epoxy adduct, elastomer particles and an auxiliary toughening agent.
Benefits of technology
High overlap shear strength and wedge impact peel strength at ambient temperature and -40°C are achieved, which significantly improves the mechanical properties of the coating.
