Loctite: A Global Leader in Adhesives and Sealants.

Founded in 1953, Loctite originated from Dr. Vernon Krieble’s groundbreaking invention of anaerobic adhesives—a revolutionary solution for loose bolts in industrial machinery. Today, Loctite offers a vast range of specialized formulas, serving industrial manufacturing, maintenance, and high-precision engineering where durability and accuracy are paramount.

FAQ

How many types of Loctite adhesives are there, and what are their different applications?

Loctite adhesives are categorized into several main types:

  • Threadlocker: For securing bolts and nuts to prevent loosening.
  • Instant Adhesive (Cyanoacrylate): Fast-drying and versatile for various materials.
  • Epoxy Adhesive: Provides high-strength bonding, ideal for structural work.
  • Silicone Sealant: For leak-proofing and waterproofing, suitable for both indoor and outdoor use.
  • Retaining Compound: For cylindrical assemblies, shafts, and bearings.
  • Anti-Seize: Prevents rust and seizing caused by high temperatures.
  • Purple (Low Strength): Low bonding strength, ideal for small screws or components that require frequent disassembly. Easily removed with standard hand tools.
  • Blue (Medium Strength): Medium bonding strength and the most popular choice. Provides excellent vibration resistance while still being removable with common hand tools.
  • Red (High Strength): Very high strength for permanent assemblies. To disassemble, high heat (approximately 250°C) and heavy-duty tools may be required.
  • Green (Wicking Grade): Very low viscosity, designed to seep into the threads of pre-assembled fasteners without the need for disassembly.

Absolutely. Loctite is specifically designed for automotive applications, such as:

  • Using threadlockers on cylinder head bolts and suspension bolts to prevent loosening from vibration.
  • Using adhesives as a Gasket Maker for oil pans or valve covers.
  • Super Glue (Instant Adhesive): Cures very quickly within seconds. Ideal for small repairs with minimal surface area, but not resistant to high impact or large gaps.
  • Epoxy Adhesive: Requires a 2-part mix. Cures slower (from minutes to hours) but provides maximum bonding strength, chemical resistance, and is excellent for gap filling.
  • General Purpose Adhesives: Typically resistant up to 150°C – 180°C.
  • Specialized Models (High Temp): Such as Loctite 272 or other high-heat resistant models, can withstand up to 230°C – 300°C.
  • Anti-Seize: Certain models can withstand up to 1,300°C (designed for anti-seize lubrication).
  • Removable types: Can be disassembled using standard hand tools (wrenches, screwdrivers).
  • High-strength types: Requires a heat gun to apply localized heat until the adhesive softens/weakens, then disassemble with tools.
  • Adhesive residue: Can be removed using solvents such as Acetone or specialized adhesive removers.

Yes, they are available as “Gel Control” or “QuickStix” (stick form, similar to a glue stick). These are designed to be non-drip, making them ideal for vertical surfaces or overhead applications.

  • Always close the cap tightly after every use.
  • Wipe the nozzle tip to remove any residual adhesive, preventing it from hardening and clogging the opening.
  • Store in a cool, dry place (avoid direct sunlight). Refrigeration is not recommended for certain types of threadlockers, as moisture can cause the adhesive to degrade faster.
  • Purchase directly from Siameast Solutions – An Authorized Distributor ensuring 100% genuine products.
