Features and benefits


  • Prevents loosening and leakage from shock & vibration: It occupies all gaps between the mating threads and cures into a hard thermoset plastic that strengthens the assembly against by adding approximately 40% to the normal loosening torque.
  • High strength: Designed for permanent applications which must not come loose. Needs localized heating to disassemble.
  • Works well on all metal substrates even passive ones like stainless steel and plated surfaces.
  • Fluorescent: It has a characteristic red colour that fluoresces under UV light. This helps during service to detect as to whether or not the product had been applied.
