In our time, a car is no longer a luxury, it has become an obligatory attribute of a resident of a large metropolis, which guarantees mobility and comfort of movement around the city. In addition to comfort, any vehicle must be safe for passengers.

Safety is influenced by various factors, for example, the quality of rubber, the correct selection of seasonal car tires. In winter, it is necessary to use special studded tires, the prototypes of which appeared at the beginning of the last century in Scandinavia.

How to improve driving safety with cyanoacrylate glue

To increase the stability of the car when driving on an icy (icy) road, bolts were installed in the through holes of the rubber, and they were fixed with the help of nuts (“thorns”). Such structures had significant weight, were short-lived, unreliable. During its existence, winter tires have undergone numerous changes, improved manufacturing technologies.

When installing studs on winter tires, the pressing method (mechanical method) is used. During operationthere is a deformation of the rubber, the geometry of the sockets intended for the installation of spikes is violated. As a result, there is a high probability of the spikes falling out, which will lead to a decrease in the quality of adhesion of the roadway to the wheels of the car, to an increase in the braking distance. Winter tire manufacturers use Permabond cyanoacrylate glue, a special adhesive material, to increase the strength of studs with a tread.

Key Features

Cyanoacrylate instant glue has the following specifications:

• 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, therefore it fills all the free space between the surfaces to be joined, while not penetrating into the micropores of the tire, preventing excessive consumption.

In practice, it was possible to prove that Permabond cyanoacrylate adhesive allows you to get a greater bond 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 tires, you need to take cyanoacrylate glue, distribute it evenly between the surface of the tread and spikes. It is enough to wait 10-15 seconds until the glue is completely cured.

Popular brand

GlueCyanoacrylate Permabond С791 guarantees ultra-fast and high-quality bonding of such materials:

• rubber;
• plastic;
• paper;
• metal;
• cardboard;
• leather;
• wood.

The composition is optimal if you need to collect 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 shades, cyanoacrylate glue is taken.

Composition Benefits

The main positive characteristics that distinguish cyanoacrylate glue from other types of glue:

• instant curing;
• quick set to maximum strength;
• compatible with various materials;
• easy operation;
• no additional solvents.

How to use cyanoacrylate glue

Before the direct application of glue, the surfaces to be glued are thoroughly cleaned, dried, and degreased. To improve the quality of bonding, you can use a special cleaner. Surfaces that have a normal roughness will give a higher grip than primed or polished ones. In order to shorten the curing time, in particular on inert surfaces, take cyanoacrylateKernel glue. Recognized as versatile, it can handle the toughest assembly and production environments.

The principle of operation of the composition

Permabond cyanoacrylate adhesives are one-component, state-of-the-art adhesives that cure by reacting with a small amount of moisture on the surface of the materials to be bonded. The chemical formula of such adhesives was specially designed for high-quality bonding of rubbers, plastics, metals, so a few seconds and room temperature are enough for the composition to fulfill its intended functional purpose.

Medium and low viscosity cyanoacrylates

Such adhesives allow:

• great for bonding together rubber, wood, plastic materials;
• connect rubber and metal, plastic and metal;
• protect parts from internal corrosion.

High viscosity cyanoacrylates

Such adhesives guarantee:

• use on porous and vertical surfaces;
• possibility of filling 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 enhances adhesion. Primer treatment is necessary to accelerate the curing time of the adhesive, as well as to fill gaps in the surfaces to be glued.

The main advantages of primers can be considered:

• acceleration of the adhesive application procedure after surface treatment with a primer;
• gluing dissimilarmaterials;
• high temperature resistant;
• odorless, non-flammable;
• durability, reliability, corrosion resistance.

How to remove cyanoacrylate glue

Many are concerned about the question of how to wash off cyanoacrylate glue. To do this, you can use special solvents or try a regular nail polish remover. It all depends on which surface you want to remove the composition from, so you first need to apply a small amount of glue to the surface to check the reaction to the agent, and only then proceed to complete elimination.

Varieties of Permabond

Permabond manufacturers have developed many different adhesives to help secure various parts. We list some of them:

• Permabond 735 is black and has improved impact resistance as well as tensile strength. It can be used to join steel, aluminum, rubber, plastic.
• Permabond CSA accelerates curing, shaping edges and bonding porous surfaces. Manufacturers offer this composition in the form of aerosols, so it is convenient to apply it to the surfaces to be glued.
• Permabond 2010 is recognized as ideal for bonding porous surfaces, also suitable for bonding inverted and vertical materials.
• Permabond 2011 does not run, suitable for bonding difficult surfaces. In particular, it is perfect for figure sculpting from variousmaterials or, for example, to restore elements of kitchen utensils. Just imagine how ugly a shiny smudge looks on a freshly glued favorite teapot. With this composition, its formation can be easily avoided.
• Permabond 4 C20 is a one-component, easily polymerized under pressure forming a thin film between the parts to be joined. Designed for high speed production lines to increase productivity. It can be used to bond various plastics, metals, rubber used in the manufacture of medical equipment.

As you can see, there are a lot of varieties of 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 ordinary PVA glue is suitable, then during complex restoration work you cannot do without cyanoacrylate, because it securely 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 recently a lot of cheap substitutes have been sold that can glue a couple of pieces of paper together at most. In this case, we are not talking about any wood, let alone metal. Purchase the composition only in a trusted hardware store.
