Related Product Features:
  • One-component red gel-like acrylic sealant with thixotropy and UV fluorescence.
  • Cures anaerobically when confined between metal surfaces for immediate low-pressure sealing.
  • Fills gaps up to 0.25mm and tolerates minor contamination from cutting and lubrication oils.
  • Bonds to both active and passive substrates, forming a medium-strength seal.
  • Provides instant pressure resistance of 1.35 MPa at a 0.05mm gap.
  • Reliably cures even with surfactant-containing cleaner residues present.
  • Offers chemical resistance to synthetic motor oil, unleaded gasoline, and ATF fluid.
  • Designed for rigid metal flange sealing in automotive gearbox casings and industrial hydraulic flanges.
FAQs:
  • What is LOCTITE 518 Medium Strength Anaerobic Flange Sealant used for?
    LOCTITE 518 is designed for rigid metal flange sealing in automotive applications like gearbox casings and engine block flanges, as well as industrial uses including hydraulic flanges, compressor covers, and gearbox joints.
  • How does LOCTITE 518 cure and what gap size can it fill?
    LOCTITE 518 cures anaerobically when confined between metal surfaces, providing immediate low-pressure sealing and filling gaps up to 0.25mm while tolerating minor contamination from cutting and lubrication oils.
  • What are the key chemical resistance properties of LOCTITE 518?
    LOCTITE 518 offers chemical resistance in various environments: it retains 50% strength in synthetic motor oil at 150°C, 5% in unleaded gasoline at 23°C, and 40% in ATF fluid at 150°C after 5000 hours.
