  • Low Strength Thread Locking Adhesive Designed for Quick & Easy Deliberate Disassembly
  • Medium Viscosity Allows for Accurate Application to Threads up to M 36 Ø
  • Non-Marking & Vibration-Proof Thread Locking Adhesive 

Weiconlock AN 302-22 is a high-quality grade of thread locking adhesive made for low strength locking and retaining. This grade will prevent unwanted loosening, but when deliberate force is applied, you will be able to easily disassembly the locked connections making maintenance fast, simple and easy.

Manufactured by Weicon in Germany, AN 302-22 has a medium viscosity and is rated for use in locking and sealing threaded parts up to M 36 (1 ½”) in diameter. This grade is widely used in the automotive, hobby and marine sectors and is purple in colour.

Weiconlock AN 302-22 is vibration proof and maintains its adhesion for extended durations. It is able to withstand temperatures up to 150°C and achieves “handling strength” (about 35% of its final) after about 10 to 20 minutes.

The video below provides even more information on how easy this high-quality thread locker is to use. Full instructions are also provided on the TDS (over on the media tab) and included on each pen shaped bottle.

Applications for Weiconlock AN 302-22 Thread Locking Adhesive

  • Locking and sealing of threaded parts and fittings that will need to be disassembled regularly.
  • Locking of bolts and fasteners in automotive and marine applications.
  • Locking threads on motors, generators and moving machinery where vibration could otherwise lead to unwanted loosening.


What do I have to do to prepare the surfaces?

Clean and dry as much as possible. Weiconlock grades will work on slightly oily surfaces but adhesion will be improved on parts that have been cleaned and degreased.

How long does it take to dry?

About 3-6 hours at room temperature for complete curing. Handling strength (usually around 35% of the final strength) will be achieved much faster; about 10-20 minutes at room temperature.

The large range quoted here is a reflection of two things; the difference in what room temperature can mean and the fact that Weiconlock AN 302-22 will take slightly longer to cure on some surfaces than others.
