  • 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.

Weiconlock AN 302-45 Pipe and Flange Sealing Adhesive is a medium strength, high viscosity grade designed for sealing metal flanges, housings and connections as well as larger diameter pipes.

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 302-45 has been tested and approved for use with Gas in accordance with DIN DVGW.

High Viscosity.

Weiconlock AN 302-45 has a high viscosity of 6.000 - 30.000 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 0.3mm.

Good Sealing of Rough Threaded Connections.

Weiconlock AN 302-45 is particuarly well suited for use on rougher threaded connections. The high viscosity of this adhesive helps it seal these connections and it can be used on threads up to M 80.

Medium Strength, Can Be Disassembled when Needed.

Weiconlock AN 302-45 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.

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..

Media Resistance   Media Resistance
Acetic acid 80% o   Oxygen
(Only WEICONLOCK with BAM)
+
Aromat, Solvent +   Phenol +
Brake fluid +   Propane +
Diesel, heating oil +   Seawater +
Edible oil +   Silicone oil +
Fuel oil +   Turpentine +
Glycocol, glycine +   Vinegar +
Helium +   Water (acidic) under PH 7 +
Hydrochloric acid +   Water PH 7 to 8 +
Isobutane +   Water (alk.) over PH 8 +
Kerosene +   Water, chlorinated +
Mineral oil +   Water, cooked o
Naphtha, petroleum +   Water, distilled +
Natural gas - dry +   Water, wastewater (sewage) +
Nitrogen gas +   Xylene, dimethylbenzene +

+ = 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.

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 cure?

Full cure is expected to take about 3-6 hours 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 302-45 will take slightly longer to cure on some surfaces than others.

All that being said, handling strength is achieved far faster. This will only take about 15-30 minutes.

Is this an equivalent to Loctite 245?

The two are very, very similar. In our experience we have seen Weiconlock AN 302-45 perform equally as well or better as a substitute many, many times. As an added bonus, Weiconlock AN 302-45 also features the unique pen-type bottle which makes use so much more natural and helps reduce wastage.

That said, it’s impossible for us to say they will both perform exactly the same way in all applications since so many things vary between each usage type.
