- Electrical-Insulating Cured Bondline
Product Description
LOCTITE EA E-60HP is a two-part, toughened structural epoxy adhesive with medium viscosity, extended working life and room-temperature cure. The resin and hardener mix 2:1 by volume and provide a 60-minute working life at 23 deg C, supporting assembly adjustment before cure. After a five-day cure at 23 deg C, the adhesive develops high lap-shear strength on prepared metal substrates together with electrical-insulating and mechanical properties. It is intended for high-performance structural bonding across supported engineering substrates where a longer processing window is more important than rapid fixture.
Key features
- Extended work life: Provides a 60-minute working life at 23 deg C for assembly adjustment before cure.
- Toughened room-temperature cure: Two-part medium-viscosity epoxy cures at room temperature to a tough off-white bondline.
- Steel and Aluminum Bond Strength: Typical lap shear strength is 30 N/mm^2 under ISO 4587 on grit-blasted mild steel and acid-etched, abraded aluminum after a five-day cure at 23 deg C.
Applications
Structural bonding applications requiring high performance and extended work life across supported engineering substrates.
