Product Overview
LOCTITE EA E-120HP is a high-viscosity, two-component epoxy adhesive designed for demanding industrial and aerospace applications. Its thixotropic formula ensures controlled flow during application while maintaining gap-filling capabilities up to 0.2 mm. Once mixed, the adhesive cures at room temperature to form a durable, amber-beige bondline with exceptional resistance to thermal shock, peel forces, and mechanical stress. The system delivers superior electrical insulation and chemical resistance, making it ideal for bonding dissimilar substrates like aluminum, steel, plastics, and ceramics.
Advanced Features
Beyond standard performance, LOCTITE EA E-120HP offers:
Extended Work Life:
• 120-minute working life at 25°C allows ample assembly time for complex parts.
• Accelerated curing at 65°C reduces fixture time to 2 hours.
Thermal Stability:
• Glass transition temperature (Tg) of 90°C ensures dimensional stability under thermal cycling.
• Withstands continuous exposure to temperatures up to 87°C in harsh environments.
Chemical Resistance:
• Exhibits ≥100% retained strength after 500 hours in motor oil at 87°C.
• Maintains 80% adhesion after 100 hours in 95% relative humidity.
Electrical Performance:
• Dielectric breakdown strength exceeds 25 kV/mm (IEC 60243-1).
Application Scenarios
LOCTITE EA E-120HP is widely utilized in industries requiring robust, high-strength bonding:
• Aerospace: Bonding nose cones, engine components, and composite panels (e.g., aluminum-to-aluminum joints).
• Industrial Manufacturing: Assembling heavy machinery, automotive parts, and tooling fixtures.
• Marine: Repairing fiberglass hulls and corrosion-resistant coatings.
• Electronics: Encapsulating circuit boards and insulating high-voltage components.
