Weiconlock AN 302-43 Threadlocking Adhesive - 20ml Pen

• High Viscosity for Accurate Application and Bonding Across Rougher Surfaces.
• Medium Strength. Can Be Disassembled with Normal Tools.
• DIN DVGW Approved for Use with Gas.
• German Hygiene Institut Approved for Potable Water.
• High Temperature (200°C)

Weiconlock AN 302-43 Thread Sealing Adhesive is a medium strength, high viscosity grade designed to permanently lock and seal threaded connections and prevent against unwanted loosening.

This grade of anaerobic adhesive is manufactured in Germany by Weicon and offers a variety of benefits. These are expanded on in the sections below:

DVGW Approved for Gas Applications.

AN 302-43 has been tested and approved for use with Gas in accordance with DIN DVGW.

High Viscosity.

Weiconlock AN 302-43 has a high viscosity of 2.000 - 7.000 mt mPa·s (according to Brookfield at 25°C). This thick nature makes it a good choice for applying to rougher surfaces and larger diameter pipes and fittings. It can cover gaps up to 0.25mm.

AN 302-43 can be used on threaded connections up to M 36.

Hygiene Institut Approved for Potable Water.

Our Weiconlock AN 302-43 has been tested and approved by the Hygiene-Institut des Ruhrgebiets. This allows it to be used for bonding in drinking water applications.

Medium Strength, Can Be Disassembled when Needed.

Weiconlock AN 302-43 cures with medium strength for bonding and sealing connections that will likely need to be disassembled at some point in the future for servicing. Disassembly will be possible using normal tools. Strength ratings are summarised further below.

High Temperature Resistance.

Our Weiconlock AN 302-43 is a high temperature grade of anerobic adhesive. This glue will withstand continuous exposure to temperatures between -60°C and +200°C.

Suitable for Use with Passive Materials.

AN 302-43 is one of our specialised grades of threadlocking adhesive. This type is very good for bonding passive materials, even without the use of an activator. For most threadlockers, a passive metal presents an issue. At best, it will slow down and/or weaken curing. At worst, it will inhibit curing all together. This is not the case with Weiconlock 302-43.

This special type of adhesive is designed to work with these passive materials whilst still achieving fast and strong cures.

The Weiconlock Pen System.

One of the features of all Weiconlock Threadlockers, Flange Sealants, Retaining Adhesives and Pipe Sealers is the pen system they use for most size containers (300ml varieties are supplied in cartridges and are the one exception).

This special pen makes accurate application natural and easy. It also helps to reduce wastage as there’s less chance of spillage.

The Weicon Pen System has been used in all kinds of industries all over the world for decades and continues to be a key point of difference for these German-Made adhesives.

Common Features of All Weiconlock Anaerobic Adhesives.

WEICONLOCK® are one-component anaerobic adhesives and sealants, especially made for metal assembly parts.

The full range covers over 60 different grades designed for everything from Thread Locking, Pipe Sealing, Flange Sealing and Retaining Cylindrical Assemblies like bearings. There are special grades for potable water applications, gas lines, oxygen service and more.

No matter the grade chosen, all types of Weiconlock Adhesive have a few things in common:

Excellent Chemical Resistance.

All grades of Weiconlock Adhesives are resistant to a large variety of different chemicals, fluids and gases. Some of the more common are summarised in the table below. A more comprehensive list is also available via the Media Tab..

+ = Good Resistance.
o = Resistant
% = Limited Resistance.
- = Not Resistant.

Easy to Use.

In general, WEICONLOCK does not require special pre-treatment as slightly oily surfaces (e.g. on as received parts) will be tolerated.

However, best results will be achieved on cleaned, degreased parts (use WEICON Surface Cleaner). If required, the parts should be slightly roughened.

WEICONLOCK is ready for use and should be applied evenly direct from the bottle/tube with the dispensing tip (avoid direct contact of dispensing tip with metal). Apply continuous bead on one side of flange, join and tighten parts quickly.

For sealing applications (pipe fitting) apply WEICONLOCK in circular motions on the thread. Screw pipe threads together and tighten until desired orientation.

Do not pour back into the bottle any WEICONLOCK fluid which had contact with metal; even smallest metal particles will cause the content of the bottle to cure. In series construction, the use of manual or automatic applicators is recommended.

Simple to Store.

WEICONLOCK can be stored in the unopened original container for at least 24 months at room temperature. Keep away from heat sources and direct sunlight. The air in the bottle/tube keeps WEICONLOCK liquid.
