- Electrically Insulating Cured Bond
Product Description
LOCTITE AA 366 is a one-part, medium-viscosity urethane methacrylate adhesive that cures with ultraviolet light for bonding, sealing, and coating metal and glass components. The uncured material is a transparent yellow-to-light-amber liquid, and a typical 20 to 30 second exposure at 100 mW/cm^2 provides high-speed UV cure. UV fixture time can be 5 seconds at 100 mW/cm^2, measured at 365 nm. The cured material combines Shore D 45 hardness with 30 kV/mm dielectric breakdown strength. Applications span electrical devices, appliance parts, and decorative metal/glass components.
Key features
- High-Speed UV Cure: Typical cure is 20 to 30 seconds at 100 mW/cm^2.
- Rapid Light-Cure Fixturing: Fixture time is 5 seconds at 100 mW/cm^2 and 365 nm.
- Cured Electrical Insulation: Dielectric breakdown strength is 30 kV/mm after cure.
Applications
Applications include unitizing electrical devices and bonding, sealing, or coating metal and glass appliance or decorative components.
