Weiconlock AN 305-18 Flange Sealing Adhesive - 50ml Pen

• High Viscosity for Larger Gap Filling and Accurate Application.
• High Temperature Resistance, Up to 200°C.
• High Strength for Hard to Disassemble, Permanent Bonds.

Weiconlock AN 305-18 Flange Sealing Adhesive is a high strength, high viscosity grade designed for sealing metal flanges, housings and connections.

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:

High Temperature Resistance.

Our Weiconlock AN 305-18 is a high temperature grade of flange sealing adhesive. This sealant will withstand continuous exposure to temperatures between -60°C and +200°C making it ideal for a wide range of equipment and applications.

High Viscosity & Larger Gap Filling Capacity.

Weiconlock AN 305-18 has a viscosity of 80.000 to 500.000 (according to Brookfield at 25°C). This thick nature makes it a good choice for applying to complex flange shapes (such as compressor connections) or narrow flanges that require very accurate application.

Partly due to its’ thick nature, Weiconlock AN 305-18 is also able to cover larger gaps than many other anaerobic adhesives. It can bridge gaps up to 0.5mm. This allows it to be used on slightly worn or misaligned flanges and still seal.

High Strength, Hard to Disassemble Joins.

Weiconlock AN 305-18 cures with high strength for permanent bonds and seals. Strength ratings are summarised further below.

Specialised tools or the application for heat (300°C) will be required to disassemble joins made with Weiconlock AN 305-18.

Immediate Sealing Effect.

Our Weiconlock AN 305-18 has an immediate sealing effect which allows for fast production times when assembling multiple connections sequentially.

This flange sealing adhesive also has an accelerated cure time. It will reach handling strength (about 35% of its full strength) after just 10-20 minutes at room temperature.

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.
