Locking Agents

Pre-treatment with Henkel Loctite locking agents completely prevents the joint from moving due to a polymer reaction.

Dri-Loc® pre-applied coatings contain microcapsules that break down during assembly, releasing an activator that initiates the polymerisation process.

The polymerised product seeps between the threads, filling all the gaps, ensuring not only locking but also sealing.

Characteristics and benefits:
  • They guarantee higher resistance to loosening than traditional mechanical solutions
  • They are available in various degrees of resistance to loosening
  • They comply with OEM and automotive industry specifications
  • They can be applied to external threads from ø 3 mm
  • They can be applied to internal threads from ø 4 mm
  • Low friction coefficients
  • They are resistant to chemicals and liquid and gaseous fluids commonly used in industrial and automotive applications
  • They are water-based and free from organic solvents, making them non-toxic
  • Extended storage time of treated parts

Loctite Dri 218
  • green color
  • low/medium mechanical strength
  • used for easily removable joints
  • operating temperature: from -50°C to +150°C

LOCTITE® 218™ is a medium-low strength, pre-applied threadlocker. The pre-applied film is dry to the
touch and remains an inert coating until the time of assembly. The microcapsules contained in the coating break during assembly, releasing an active ingredient that initiates the polymerisation process. Typical applications aim to prevent the loosening of threaded fastenings. Particularly suitable for situations in which the
threaded parts must be ready for immediate use in an adhesive joint in a high-volume production environment, where it may not be possible to use a liquid product. After polymerisation, the product
also acts as a sealant.

Loctite Dri 211
  • red color
  • medium/high mechanical resistance
  • generic use
  • operating temperature: from -50°C to +150°C

LOCTITE® DRI 211™ is a pre-applied coating for threaded fastenings and fittings. The microcapsules
contained in the coating break during assembly, releasing an active ingredient that initiates the polymerisation process. The product prevents loosening due to vibration and leakage onto threaded fastenings. After polymerisation, the product
also acts as a sealant.

Loctite Dri 2040 / 204
  • red color
  • high mechanical strength
  • ideal for passivated substrates and stainless steel
  • operating temperature: from -50°C to +150°
  • complies with the requirements of the DIN 267-27 standard

LOCTITE® DRI 2040 is a general-purpose medium to
high strength pre-applied threadlocker adhesive. When
cured, this product will also act as a thread sealant. Dryto- touch coatings contain microcapsules which crush during assembly, releasing an active ingredient, which
starts the curing process.

Loctite Dri 2045
  • red color
  • medium/high mechanical resistance
  • high resistance to high temperatures and temperature aging
  • high resistance to chemicals
  • operating temperature: from -50°C to +180°
  • complies with the requirements of the DIN 267-27 standard

LOCTITE® DRI 2045™ is a medium-high strength pre-applied threadlocker with good compatibility with a variety of substrates, designed especially to meet the demands of automotive specifications.
It is suitable for use on flat and passivated metal surfaces. This product presents good resistance to heat and a thermal ageing capacity of up to 220°C as well as good resistance to solvents. The pre-applied film is dry to the touch and remains an inert coating until the time of assembly. The microcapsules contained in the coating break during assembly, releasing an active ingredient that initiates the polymerisation process. LOCTITE® DRI 2045™ prevents the loosening of threaded fastenings. After polymerisation, the product also acts as a sealant. Particularly suitable for situations in which the threaded parts must be ready for immediate use in an adhesive joint in a high-volume production environment, where it may not be possible to use a liquid product.
