Application Results In practical use, the adhesive demonstrated outstanding performance in the aerospace project. Under harsh conditions (e.g., high temperature, humidity), the adhesive layer remained stable, showing no delamination or corrosion. Additionally, its excellent adhesion and weather resistance enhanced the structural integrity of the aircraft fuselage, improving flight safety and reliability.
