NEOMER Technology of Cyberbond

Generally Cyanoacrylate Adhesives bond a lot of different materials relatively quickly with and among each other. This is the reason Cyanoacrylates are also called Super Glues. Engineers out of the industrial adhesive world do not really like this description, because setting times and also the ability to bond certain materials are relative. Not all materials can be bonded respectively cannot be bonded in the same time or with the same strength. General statements can just be contemplated as vague, because nothing is defined. This is the reason, why many people trying to repair broken parts at home are disappointed about the results. The negative general image of bonding results out of this. On the other hand this is a full contradiction to the high usage of adhesives in general and of Cyanoacrylates in special in the overall industry. Just have a look to the automotive or electro-/electronic industry. Without adhesives they could not go into production anymore.

Cyberbond offers various industrial Cyanoacrylate Adhesives. There is a range of special products designed to bond e.g.  rubbers. Other grades perform better to bond metals or plastics. Again other not so aggressive Cyanoacrylates are used in the medical section. We could continue with a list like this and should also not forget to mention the optional use of additional supporting products like Activators or Primers to which the hobby user at home has normally no access to.

One crucial criteria we want to concentrate on here is the surface of a mating part. Taking gaps and roughness not into consideration right now, we want to contemplate porosity and pH-value of a surface. Therefore you should know that acid surfaces slow the setting time down or avoid the polymerisation completely, while an alkaline surface accelerates the bonding process.  

The Neomer Technology is somehow linked to the subject acid surfaces. If you take just wood e.g. which has an acid and porous surface, you will realise a slow polymerisation.  Sometimes it even can happen that the Cyanoacrylate wicks into the wood structure, disappears so to say, and there is nothing left for final bonding. To overcome this you can take a higher viscosity (thicker) product so that at least the soaking effect is not relevant anymore, but the slow setting time is not avoided (minutes).

Cyberbond offers with the Neomer Technology further developed and heavily improved Cyanoacrylates. These products result in the following: the Cyanoacrylate contains an additive which neutralises the acidity and enlarges the surface tension. The adhesive cannot be soaked away anymore and the polymerisation takes place much faster.

The base of these accelerated or so called surface insensitive grades is not new and was developed more than 20 years ago. Different and various chemical reactions have to be considered, but they all have the same disadvantage. If a Cyanoacrylate Adhesive is accelerated in the described way, you have to stabilise the final product higher in order to reach sufficient shelf life for finished goods. But this higher stabilisation slows down the setting time on other materials like rubber, plastic etc. dramatically respectively prevents the polymerisation completely.

With CB 2600 and CB 2610  Cyberbond lounges two grades with the Neomer Technology that do not only bond wood, leather, cardboard, even paper quickly, but also rubber and plastics in the fast known way. The products differ in their viscosity. CB 2600  is thin like water, while CB 2610  has a very comfortable to use viscosity of 120 mPa*s. CB 2610  should be considered as the standard, but in the end the choice is dependent on what has to be bonded.
