Nowadays, a car is no longer a luxury, it has become an obligatory attribute of a resident of a large metropolis, guaranteeing mobility and comfort of movement around the city. In addition to comfort, any vehicle must be safe for passengers.Various factors affect safety, for example, the quality of rubber, the correct selection of seasonal car tires. In winter, it is necessary to use a special studded rubber, the prototypes of which appeared at the beginning of the last century in Scandinavia.

How to improve traffic safety with cyanoacrylate glue

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.

Main characteristics

Cyanoacrylate second glue has the following technical characteristics:

  • Excellent adhesion to metal and rubber;
  • Fast curing;
  • Large operating temperature range.

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.

Popular brand

Permabond C791 cyanoacrylate glue guarantees ultra-fast and high-quality bonding of such matheriaLS:

  • Rubber;
  • Plastic;
  • Paper;
  • Metal;
  • Paperboard;
  • Skin;
  • Wood.

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.

Advantages of the composition

The main positive characteristics, which favorably distinguish cyanoacrylate glue from other types of glue:

  • Instant solidification;
  • Fast set of maximum strength;
  • Compatibility with various materials;
  • Ease of operation;
  • No additional solvents.

How to use cyanoacrylate 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.

The principle of operation of the composition

< p>Permabond cyanocrylate adhesives are one-component modern adhesives that harden due to the interaction on the surface of the joined materials with an insignificant volume of moisture. The chemical formula of such adhesives was specially developed for the high-quality connection of rubbers, plastics, metals, so a few seconds and room temperature are enough for the composition to fulfill its direct functional purpose.

Cyanocrylates of medium and low viscosity

Such adhesives allow you to:

  • Perfectly glue together rubber, wood, plastic materials;
  • Connect rubber and metal, plastic and metal;
  • Protect the parts from internal corrosion.

High viscosity Cyanocrylates

Such adhesives guarantee:

  • Use on porous and vertical surfaces;
  • The ability to fill gaps up to 0.5 mm;
  • Minimum curing time;
  • High-strength adhesion (up to 25 MPa).

About Permabond Primers and Catalysts

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:

  • Acceleration of the adhesive application procedure after surface treatment with a primer;
  • Bonding of dissimilar materials;
  • Resistance to high temperatures;
  • Odorless, incombustible;
  • Durability, reliability, corrosion resistance.

How to remove cyanocrylate glue

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 varieties

Permabond manufacturers have developed many different adhesives that help to securely attach different parts. Let's list some of them:

  • Permabond 735 is black, has improved characteristics for impact resistance, as well as for tensile strength. It can be used to connect steel, aluminum, rubber, plastic.
  • Permabond CSA accelerates solidification, gives the edge a certain shape, glues porous surfaces. Manufacturers offer this composition in the form of aerosols, so it is convenient to apply it to the glued surfaces.
  • Permabond 2010 is recognized as an ideal tool for connecting porous surfaces, it is also suitable for connecting inverted and vertical materials.
  • Permabond 2011 does not spread, it is suitable for joining complex surfaces. In particular, it is perfect for figure modeling from various materials or, for example, for restoring elements of kitchen utensils. Just imagine how ugly a shiny smudge looks on a newly glued favorite teapot. With this composition, its formation can easily be avoided.
  • Permabond 4 C20 is a one-component, easily polymerized under pressure with the formation of a thin film between the connected parts. Designed for use on high-speed production lines to increase productivity. It can be used to glue various plastics, metals, rubber used in the manufacture of medical equipment.

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.
