Reduce Friction, Corrosion and Wear with our Anti-Seize Lubrication Pastes and Sprays

Weicon Anti-Seize Range Image Banner Image - Available from Associated Gaskets

Moisture, friction and all kinds of other influences can lead to damage such as corrosion, wear and even the seizure of machines and installations. Extensive repair and maintenance work, at considerable cost, is the result.

These problems are even more pronounced when the application conditions feature one (or more) of the following:

♦  High operating temperatures.
♦  High pressure loads.
♦  Exposure to the weather.
♦  Aggressive chemicals.
♦  The influence of other media.

Our Weicon range of Anti-Seize Assembly Pastes have been specially developed for these requirements. They are used as protecting and separating agents (and lubricants) for highly stressed parts, especially at high temperatures.

Anti-Seize Stops Corrosion and Seizing on a bolt

In many demanding industrial applications, convention separating agents or lubricants (such as mineral oils and greases) cannot provide sufficient lubrication and protection. Since they are based on optimally balanced solids and specially selected additives, the Weicon Anti-Seize range can be used in these extreme environments, and provide long lasting performance.

The basic components in our Anti-Seize solutions are made from synthetic oils. These have a considerably lower sulphur content than products containing mineral oil. A residue-free vaporisation of the oil at temperatures between +200°C and +250°C is therefore possible.

This is particularly important in the case of stainless steels (e.g. for VA material) to prevent stress-corrosion cracking.

Due to the special formulation and the very fine grinding of the solids contained in Weicon Anti-Seize, irregularities in the surface being protected are completely filled – even to a layer thickness of only 12 μm. Only a perfectly sealed surface guarantees a reliable protection against corrosion. An additional sealing effect thus results for special applications, such as flange connections.

Weicon Anti-Seize Lubricating and Assembly Pastes protect against the following:

♦  Corrosion, seizure and wear.
♦  Stick-slip phenomena.
♦  Oxidation and fretting corrosion.
♦  Electrolytic reactions (aka cold welding).

All grades of Weicon Anti-Seize are free of sulphurous additives and halogens. They have good adhesion characteristics and are abrasion proof. They are also resistant to hot, cold and salt water. Their extremely low friction also allows for easy disassembly of treated components when it is required.

Anti-Seize Spray being applied to a flange face

In addition, Weicon Anti-Seize assembly pastes are excellent lubrication for statically high-stressed parts and slowly rotating machines (as long as corresponding re-lubrication intervals are observed).

With their dual capabilities as lubricants and corrosion protection agents, Weicon Anti-Seize offer the benefit of rationalisation; in terms of saving time, reducing the need for multiple maintenance products, and reducing costs.

These products are used quite sparingly. At a layer thickness of 0.01mm, 1kg of Anti-Seize is enough to cover a surface area of approximately 45m².

Our 4 Types of Anti-Seize Assembly Lubricants.

To suit the needs of different applications we are pleased to offer four different types of Anti-Seize. These are high quality, long lasting and effective lubrication and protection products but their composition and performance capabilities differ.

Together the four different grades cover everything from common marine, automotive and facility maintenance work, to demanding food grade, high temp or aggressive chemical applications. All are available in a range of sizes and container styles and the differences between each is summarised below:

VKA Welding Load Test: 2000 N (DIN 51350)

The assembly paste was developed to resist extreme conditions. It is highly sticky, water repellent and resistant to sweet, salt and hot water as well as steam. The high nickel component furthermore provides protection against corroding and corrosive solvents which are contained in diluted hydrochloric acid, sulphur or nitric acid, among others. Anti-Seize Nickel can be applied at a large temperature range between -30°C to +1,450°C.

Anti-Seize Nickel serves as corrosion protection and high-performance fitting grease for static and dynamically extremely stressed screw connections and installation parts and the application at slowly rotating system in the high-temperature range.

The paste protects against corrosion, seizing, wear, stick-slip effects, oxidation and friction corrosion as well as electrolytic reactions, the so-called cold-sealing. For example, Anti-Seize Nickel can be used on seals, valves, screw connections, gear wheels, bearings, jets, conveyor belts, studs, tools or cylinders.

Could Ceramic Insulation Paper Solve Your Temperature Woes?

Ceramic Fibre Paper Glass; Thermal Insulation;

One of the main problems generally encountered when searching for a high temperature insulation material is that in order to withstand elevated temperatures, a trade-off is usually made with mechanical strength resulting in materials that are brittle, porous, fibrous and generally difficult to handle. If these properties are what are causing trouble in your high temperature insulation application, then you may want to read on and find out more about AG’s Lytherm Ceramic Insulation Paper.

Really, a heat resistant paper?

We know it sounds strange but Lytherm isn’t your normal paper manufactured from organic tree wood. It’s actually manufactured from high purity alumina-silicate fibres. These are ceramic-based inorganic fibres that are often used as a refractory material in many high temperature industrial applications and processes where temperatures reach over 1000ºC.

The fibres are washed and spun in a special process to remove foreign particles and to control the content of unfiberized shot. The resulting product is a thin, white sheet material that is lightweight but strong.

Lytherm Ceramic Insulation Paper Close-Up


What are the advantages of ceramic fiber paper?

Ceramic Insulation Papers offer many advantages over other forms of insulation. They are thin, flexible and lightweight while still able to remain extremely stable and easy to handle. Lytherm is so stable that even when exposed to water, steam or oil it will return to its original thermal and physical properties upon drying!

Lytherm also exhibits extremely low thermal conductivity and heat storage. This makes it particularly useful for heat containment in tight places or where a uniform thickness material is required. It is also resistant to a wide range of chemicals meaning it can be used in a diverse range of applications.

Other benefits include:

♦ Excellent compression recovery (very important for sealing).
♦ Good dielectric strength.
♦ Low heat storage.
♦ Very little shrinkage. Even at extreme temperatures.

Best of all it can be cut into shapes, wrapped, formed or slit into rolls without falling to pieces. This means you can achieve the exact shape of insulator that you require.

Lytherm Cermic Fiber Paper Compressed


Where is ceramic insulation paper typically used?

Ceramic insulation papers are mainly used as lining materials, for high temperature seals, primary insulation or as a filler. Within these broad descriptions, there’s a lot of specific uses. Just some of them include:

♦ Lining of doors and walls for furnaces and kilns.
♦ Insulation for wood-fired pizza ovens.
♦ Lining and insulation for glass making.
♦ Making high temperature gaskets and seals.
♦ Insulation around engines and exhaust systems in the marine and automotive sectors.
♦ Pump insulation.
♦ As a filler for insulation batts and blankets.

These really are just some of the countless applications we’ve seen for Lytherm ceramic paper over the years. If you think Lytherm might be suitable for your application, it’s worth speaking to one of our experienced customer service team members. They’ll be happy to help with information on sizes, fabrication options and anything else you need to know.

Ceramic Fibre Paper Glass

Is there anything to be aware of?

Most grades of Lytherm Ceramic Insulation Paper contain a low percentage of organic binder that may burn off when initially exposed to elevated temperatures. In most applications, this should not be a concern – merely something to be aware of.

In applications where this could be an issue, AG can also supply a completely inorganic binderless grade. This specialised type is able to handle temperatures up to 1650ºC whereas the standard grade is rated to a (still fairly impressive) 1260°C.

To find out more about this product including what thicknesses and sizes are available we suggest heading over to the product page on our website where you will be able to find all the technical data. Alternatively, to learn more about all the fabrication options we offer for our Lytherm paper, you can get the details of your local AG branch here.

Sealon PTFE Gasket Tape Demonstrated In Our New Video

Sealon PTFE Gasket Tape is an incredibly versatile product. Made from expanded PTFE (AKA Teflon), Sealon replaces conventional gaskets and can be applied directly to the flange face. It’s a simple, fast, and permanent alternative to using a cut-gasket and is versatile enough to cover many different sealing applications.

One of the things we’ve come across over the years though is the misconception that it would be hard to install. After all, a tape replacing a gasket; there has to be some trick to it right? Not really. You definitely need to ensure that Sealon is ok for your application (pressure, temperature, medium, compression all continue to play a part) but apart from that it’s really quite simple.

Sealon PTFE Instant Gasket Tape from Associated Gaskets Australia

Rather than try to explain in words how easy it is to seal a flange with Sealon, we decided the best thing we could do is to show it. To do this, we’ve put together the video below.

Every roll of Sealon is produced for pure PTFE which allows it to offer exceptional chemical resistance. In fact, it’s resistant to most chemicals with the exceptions of elemental fluorine and molten alkali metals. It’s also DVGW rated for use in sealing gas and meets FDA requirements for food application. A variant (without the adhesive backing) is also available for oxygen sealing (BAM approved).

Sealon withstands anything between -232°C and +315°C and is soft enough to compress at minimal torque.

Sealon PTFE Gasket Tape Sizes

Width (Metric) Width (Imperial) Length
3mm 1/8″ 30 Metres
5mm 3/16″ 20 Metres
7mm 1/4″ 15 Metres
