Tough removable screw retainer and sealing compound – single-handed dispensing system

High-strength bonding

  • Can only be removed once heated up to > 250°C

Suitable for screw connections exposed to high stresses

  • A 100 % seal is achieved - no additional securing parts are necessary

  • Protects against corrosion due to friction and against rust

Excellent media and thermal stability

Universal products with wide range of applications

Prevents detachment, e.g. through vibration and shock loads

No unwanted locking problems such as with mechanical screw retainers, for example

High resistance

Resistant to a large number of bases, gases, solvents, oils and fuels (see resistance list)

Silicone-free, solvent-free and oil-free

DOS system:

  • Practical one-handed operation thanks to the clever turn lock

One hand always remains free.

  • Continuously adjustable dispensing system

Dispensing can be adjusted to suit the application, and to keep consumption and costs to a minimum.

  • No residue material in dispensing neck

Costs optimised thanks to emptying with virtually no remaining product


The following plastics can be affected in the event of prolonged exposure: ABS, celluloid, polystyrene, polycarbonate (Macrolon), PMMA (Plexiglas), polysulfone, SAN (lurane, Tyril), Vinidur, vulcanised fibre and painted surfaces.

NSF-tested in accordance with NSF/ANSI 61 for use in service water and drinking water

Application area

For securing, fastening and sealing threaded connections such as bolts, stud bolts, nuts, threaded plugs, thread inserts, ball bearings and roller bearings, which do not normally have to be detached. The high-strength threadlocker is for use in the automotive and commercial vehicle industry, in metalworking and tool manufacturing, shipbuilding, mechanical engineering and engine construction, and electrical and electronics construction.


This liquid plastic cures when in contact with metal in the absence of oxygen. The contact surfaces must be dry, dust-free and grease-free. Moisten the adhesive surfaces sufficiently and put them together immediately.

For more information, please refer to the technical data sheet.

Permeation is the process by which a chemical moves through the material of a protective glove on a molecular level. The time from the initial contact between the chemical and the glove to the permeation of the material is the breakthrough time.
Measured breakthrough time

≥ 240 min
≥ 480 min

Important information:

The information given is based on experience and laboratory conditions and is designed as a guide. However, the actual suitability of a glove depends on the individual conditions of its use and must be confirmed by an appropriate test under operational conditions. Given the variety of materials and chemicals used, the possibility of incompatibility or usage problems for the wearer cannot be excluded in individual cases. We would be happy to advise you about optimum solutions.
