Loctite

Loctite

Loctite is a Henkel brand of industrial adhesives, sealants, and surface treatments built on the 1953 invention of anaerobic threadlocking chemistry. The line covers acrylics, methyl methacrylates, epoxies, anaerobics, cyanoacrylates, silicones, urethanes, and UV-cure formulations used across maintenance, manufacturing assembly, and automotive aftermarket work.

Core families that Chemical Concepts supports include the Loctite threadlocker series (222, 242, 243, 271, 272, 290) for locking threaded fasteners against vibration, retaining compounds (609, 620, 638, 648, 680) for cylindrical assemblies, anaerobic gasketing (510, 515, 518, 5188) for flange sealing, and thread sealants (545, 567, 592) for hydraulic and pneumatic fittings. Structural bonding draws on Loctite methyl methacrylate adhesives (H4500, H8000, AA series) and Hysol epoxies (E-120HP, E-60HP, EA 9460 family) for bonding metals, composites, and plastics. The automotive aftermarket lineup includes Teroson seam sealers, anti-seize and lubricating compounds (LB 8009 silver, LB 8150 copper), gasket dressings, and cyanoacrylate instant adhesives.

Vernon Krieble developed the first Loctite threadlocker in his Trinity College lab in Hartford, Connecticut. Henkel acquired the brand in 1997, and Loctite remains anchored in Rocky Hill, Connecticut for North American operations.

Chemical Concepts stocks the industrial Loctite portfolio and pairs every order with technical selection support. To match a Loctite product to your application, call (800) 220-1966 or email [email protected].

Key Product Families

  • Threadlockers (222, 242, 243, 271, 272, 290): Anaerobic adhesives that lock threaded fasteners and stop vibrational loosening, from low-strength removable to permanent high-strength grades.
  • Retaining compounds (609, 620, 638, 648, 680): Anaerobic adhesives that retain cylindrical assemblies (bearings, bushings, shafts) on slip or press fits.
  • Thread sealants (545, 565, 567, 592): Thixotropic anaerobic sealants for hydraulic, pneumatic, and gas fittings.
  • Anaerobic gasketing (510, 515, 518, 5188): Form-in-place gaskets for rigid flanged metal assemblies including transmissions and pumps.
  • Methyl methacrylate structural adhesives (H4500, H8000, AA series): Two-part toughened acrylics for high-strength bonding of metals, composites, and plastics with minimal surface prep.
  • Hysol epoxies (E-120HP, E-60HP, EA 9460 family): Two-part room-temperature curing epoxies for structural bonding, potting, and encapsulation.
  • Anti-seize and lubricants (LB 8009 silver grade, LB 8150 copper grade): Solid-film fastener protection for high-temperature assemblies and corrosive environments.
  • Teroson seam sealers: Polyurethane and MS polymer body sealers for automotive seam sealing, panel bonding, and corrosion protection.
  • Cyanoacrylates (401, 414, 416, 420, 454, 495): Fast-cure instant adhesives for small-area bonding of metals, plastics, and rubber.
