  • Used to retain critical components like shafts, gears, pulleys, bushings and sprockets in applications such as motors, pumps, gearboxes and machinery

  • Provides a permanent, vibration resistant bond even on oily surfaces

  • Strength: High - suitable for applications requiring maximum retention strength

  • Handling Strength: Bonded parts can be handled after 5 minutes

  • Temperature Resistance: Suitable for applications from -55°C to +150°C

  • Chemical/Solvent Resistance: Resists fuels, oils, greases and many chemicals

  • Prevents corrosion of bonded metal surfaces
