Product Description
LOCTITE EA E-05CL is a two-part, fast-setting epoxy adhesive that cures at room temperature to an ultra-clear bondline. The medium-viscosity system is mixed 1:1 by volume and has a 3-minute working life at 25 deg C, supporting rapid assembly. Once cured, the toughened epoxy combines low shrinkage, flexibility, peel resistance, electrical insulation, and resistance to a range of chemicals and solvents. It bonds supported materials including metals, glass, ceramics, most plastics, rubber, wood, and masonry. Applications include flex-circuit bonding, cable boots, component staking, and clear fillet bonds.
Key features
- Short Working Life: Mixed adhesive has a 3-minute working life at 25 deg C.
- Ultra-clear flexible bondline: Room-temperature cure produces an ultra-clear bondline with 80% elongation in ASTM D638 testing.
- Electrical Insulation and Chemical Resistance: Fully cured epoxy is electrically insulating and resists a range of chemicals and solvents.
Applications
Applications include flex-circuit bonding, cable boots, component staking, and clear fillet bonds.
