Product Information

The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration.

Features:

  • Tolerates minor contaminants, including industrial oils
  • High strength on all metals, including passive substrates (e.g. stainless steel)
  • High temperature resistance
  • Ideal for shafts, gears, pulleys and similar cylindrical parts
