Cyberbond Instant Gasket

In many cases Cyberbond “S” series products are able to replace traditional rigid joint faces if used in constructions. When used to seal a flange Cyberbond offers the advantage of protecting the joint against corrosion. There are different strength classes available and the designer has the choice to keep the mating parts easily disassemble or he can improve the mechanical resistance of the total construction by selecting a higher strength product.

Resistance against Oil and Gas

Cyberbond is resistant against most used oils and gases. Sealing tests below 1 bar can be done after full assembling of the parts. In order to check the properties fully respectively before filling the component with a medium the sealant should have been polymerised by at least 70 % in order to avoid infiltration.

Another great advantage of the Cyberbond sealant “S” series is that no joint settlement can be observed. Compared to traditional rigid flanges there is no need to re-tighten the flange bolts. The storage of just one liquid gasket compared to many solid types offers further benefits.

Application of Instant Gaskets

The application of the Cyberbond product can be done fast and without causing any problems. In the line the application is done by a robot or silk-screen methods. For smaller applications or in the maintenance Cyberbond can be applied simply from the bottle or tube. A brush can also be used to spread the product. Complicated designs and joints are easily sealed by using Cyberbond “S” series grades, but a certain overlap width must be granted (about 5mm minimum; about 3mm minimum around bold holes).

Cyberbond R - Retainer

Threads, shafts and bearings are to be retained durably and reliably. Generally the need to dismantle these joints easily is not required. Therefore, the high strength retainers of the Cyberbond “R” series grades meet the requirements of these types of joints. When Cyberbond is used a uniform stress distribution throughout the joint is achieved, which means dynamical and statical loads can easily be withstood. In contrast to the benefits of these modern liquid retainers, traditional cylindrical assembly methods do have the following disadvantages:

- in the case of press fits or shrink fits high machinery costs are involved and the parts have to be designed very accurately and become very expensive joints,

- in common drive assemblies pins, splices or adjusting springs are often used which have the disadvantage of fretting corrosion and high punctual stress,

- due to various elongation figures in different metals a welding or soldering process is quite often limited or even impossible.

When Cyberbond retainers are selected all these disadvantages disappear. By means of a room temperature cured Anaerobic Adhesive, higher strength values can be achieved compared to assembly method like e.g. a press-fit where no adhesive is used. When Cyberbond retainers are used the following advantages are gained:

- small gaps can be bridged, which allows less costly designed mating parts,

- friction corrosion is avoided,

- different elongation figures of mating parts can be balanced.

Cyberbond S - Sealing

Besides sealing fine threads Cyberbond “S” series grades can also seal pipe fittings due to their ability to resist most chemicals. Cyberbond products offer a outstanding stability in chemicals. As with thread locking the space between the threads is completely filled with adhesive and this seals the fitting. Depending on which sealant has been selected, initial leak tests may be carried out immediately as the liquid sealant cures relatively quickly. Early testing should not exceed 1 bar. After complete polymerisation of the sealant, pressure can be maximised until complete destruction of the joint. Like any Anaerobic Adhesive and sealant the selected metals and design of the parts have a huge influence when choosing a Cyberbond sealant. For example a larger thread needs more adhesive to fill the space and will give higher torque values when cured. In this case a low strength Cyberbond sealant should be selected, especially if easy disassembly is required.

Use on Building Sites and Household Applications

Anaerobic sealants are recommended for industrial applications. The use in the building industry should be avoided as leaks are provoked by undefined temperatures, readjustments and in many cases dirty sealing surfaces.

Craftsmen who want to seal defined and clean threads quite often prefer using Cyberbond Anaerobic Sealant, realising the benefits and advantages they have over traditional methods of sealing, such as Teflon tape or hemp. But in this case you should consider individual laws in the various countries. There exists a lot of national gas and tap water approvals, but the approvals quite often limit the usage of an Anaerobic sealant heavily.

Gas and Drinking Water Approvals

To reach a contemporary new gas or drinking water approval in the European Union is relatively difficult or just not really possible. Again each country has got still its own laws and ideas. To Cyberbond’s mind such an approval is also not crucial for component producers.

If for example a gas heater producer needs to seal a component he will certainly approve the whole device, which includes already an Anaerobic sealant. A separate approval of the sealant itself is not necessary. For this reason this producer can work with a tailor made sealant, which he will specify for this application internally.

That said, Cyberbond offers CB SH 27a product that holds the German DVGW EN 751-1 gas approval. But in Germany such an approval does not allow to use the product in house installations.

Cyberbond T - Threadlocker

Vibration may cause problems such as the self-loosening of threads. By applying the Cyberbond 'T' series grades, this problem is solved. Cyberbond maintains the on-torque given on a thread, which prevents the self-loosening process. At the same time Cyberbond fills the voids in the threads, which seals them and prevents corrosion. Liquid Cyberbond is simply applied straight from the bottle or tube. After assembly the product will cure completely and fix the mating parts. The complete thread should be wetted to ensure the load is distributed along the total length of the thread. A slight thixotropic nature of the products helps to prevent the product flowing away and is also responsible for the optimal coverage of the thread. By selecting the correct Cyberbond grade, use of mechanical aids may not be necessary at all.

Strength Categories

When choosing a product, consideration should be given to the various strength classes available, together with the material of the thread itself and the design. If threads need to be disassembled e.g. a nut is positioned in a difficult to reach area, but has to be undone later, then none other than a medium strength grade such as CB TM 11 or CB TM 44 should be used.

In connection with threadlocking, friction values play a special role. The friction value of Anaerobic Cyberbond adhesives is between 0.2 and 0.3. For special applications requiring lower friction values we recommend Cyberbond TM 44.
