To increase the stability of the car when moving on an icy (icy) road, bolts were installed in the through holes of the rubber, they were fixed with nuts ("spikes"). Such structures had considerable weight, were short-lived, unreliable. During its existence, winter tires have undergone numerous changes, the technologies of their manufacture have been improved.
When installing spikes on winter tires, the pressing method (mechanical method) is used. During operation, the rubber is deformed, the geometry of the sockets intended for the installation of spikes is violated. As a result, there is a high probability of spikes falling out, which will lead to a decrease in the quality of the roadway's grip with the wheels of the car, to an increase in the braking distance. To increase the fastening strength of spikes with a tread, manufacturers of winter tires use Permabond cyanoacrylate glue – a special adhesive material.

Cyanoacrylate second glue has the following technical characteristics:
For example, Permabond c791 cyanoacrylate glue has all the above characteristics, it can be used to install spikes on car tires. It has a certain viscosity, so it fills all the free space between the connected surfaces, while it does not penetrate into the micropores of the tire, preventing excessive consumption.
In practice, it was possible to prove that Permabond cyanoacrylate glue allows you to obtain greater joint strength than the rubber tire itself. The glue is able to function at temperatures from -40 to +120 degrees Celsius. Before putting metal spikes on car tires, you need to take cyanoacrylate glue, distribute it evenly between the surface of the tread and the spikes. It is enough to wait 10-15 seconds until the glue is completely cured.
Permabond C791 cyanoacrylate glue guarantees ultra-fast and high-quality bonding of such matheriaLS:
The composition is optimal if it is necessary to assemble small parts. Cyanoacrylate glue "Moment" has a low viscosity, so it easily penetrates into porous materials, increases the adhesion strength of the surfaces to be glued. It is used in the manufacture of street lamps, reliably protecting them from dust and excess moisture. For reliable sealing of rubber seals and plafonds, it is cyanoacrylate glue that is taken.
The main positive characteristics, which favorably distinguish cyanoacrylate glue from other types of glue:
Before the glue is applied directly, the surfaces to be glued are thoroughly cleaned, dried, and degreased. To improve the quality of bonding, you can use a special cleaner. Surfaces with the usual roughness will give a higher grip than primed or polished ones. In order to reduce the curing time, in particular on inert surfaces, take Kernil cyanoacrylate glue. It is recognized as universal, with its help you can solve the most stringent assembly and production conditions.
Such adhesives allow you to:
Such adhesives guarantee:
The use of a primer helps to strengthen the adhesion. Primer treatment is necessary to speed up the curing time of the adhesive, as well as to fill the gaps at the glued surfaces.
The main advantages of primers can be considered:
Many people are concerned about the question of how to wash off the cyanoacrylate glue. To do this, you can use special solvents or try a regular nail polish remover. It all depends on which surface you need to remove the composition from, so first you need to apply a small amount of glue to the surface to check the reaction to the product, and only then proceed to complete elimination.
Permabond manufacturers have developed many different adhesives that help to securely attach different parts. Let's list some of them:
As you can see, there are a lot of varieties of the composition. In particular, they are pleased with their wide functionality. Therefore, in any life situation, you can choose exactly the option that will be optimal for connecting parts. And if in some cases the usual PVA glue is suitable, then during complex restoration work it is impossible to do without cyanocrylate, because it reliably fixes the parts with a guarantee that they will be able to perform their functions for a long time. The main task of the buyer is not to fall for a low-quality fake, since a lot of cheap substitutes have been sold recently, which are able to glue a couple of sheets of paper together at most. We are not talking about any wood, and even more so metal, in this case. Buy the composition only in a trusted construction store.
