Product detailed description

Loctite 518 (IDH 1522033) – Surface Sealant for Metal Flanges

Loctite 518 is an anaerobic sealant that cures without air between metal surfaces. This product is designed for sealing rigid metal flanges, where it provides a reliable seal and resistance to chemicals, pressure and temperature fluctuations. Loctite 518 offers excellent performance on both active and passive metals such as steel and aluminum, and its thixotropic nature prevents sag.

Available packaging: Loctite5 Loctite 518 50 ml or Loctite

Benefits:

  • Cures in the absence of air between two metal surfaces.
  • Resists low pressure immediately after assembly.
  • Excellent chemical resistance to oils, water, glycols and most automotive fluids. joints up to 0.25 mm.
  • Flexible to minor flange movements and corrosion resistant.
  • Ideal for machined metal flanges and joining metal surfaces.

  • Temperature resistance: -55°C to +150°C
  • Pressure resistance: Immediately after application, it is resistant to low pressure; after full cure, it can withstand higher pressures.
  • Full cure time: 24 hours at room temperature
  • Application:
    Loctite 518 is suitable for sealing rigid metal flange joints, for example in gearboxes, engine blocks. This product is used in the automotive, energy and mechanical engineering industries. It is ideal for metal surfaces such as steel, cast iron and aluminum.

    Use for application:

    • Surface preparation: Use Loctite SF 7063 cleaner to thoroughly degrease and remove dirt. If you prefer more environmentally friendly products, Loctite SF 7061 is the ideal choice, which ensures gentle but effective cleaning. hydrocarbons.

    • Removing sealant and adhesive residues:If you need to remove old sealant, adhesives or other materials from a bonded surface, Loctite SF 7200 is the ideal choice. Its application is simple - just apply and leave to act, which will easily peel off the material. Be careful with painted and plastic parts.

    • Surface activation:When applying anaerobic sealant at temperatures below 5 °C, it is recommended to first treat the surface with Loctite SF 7240 or Loctite SF 7649. The activator accelerates curing on passive metals or at low application temperatures. surfaces: To thoroughly remove old deposits and dirt, including oils, greases and other industrial dirt, use Loctite SF 7840. This water-based, all-purpose cleaner is biodegradable and ideal for effective cleaning of various surfaces without damaging the material.

    • Cleaning hands after work: After completing the application, use Loctite SF 7850, which is suitable for effective hand cleaning. This biodegradable cleaner removes oils, greases and other dirt. Choose the right LOCTITE gasket for your application. ';shoptet.content.colorboxFooter = '
