Specification

Removable screw retainer and sealing compound – one-handed dispensing system

Medium-strength bonding

Can be removed using normal tools

Can also be applied to stainless steel and passivated surfaces

No "accelerator" or "activator" required

Excellent media and thermal stability

Universal products with a wide range of application

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.

Application

Application area

For medium-strength retaining, fixing and sealing of threaded connections such as screws, stud bolts, nuts and threaded plugs, which are supposed to be detached again with normal tools. The medium-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.

Instructions

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.
