Nowadays, a car is no longer a luxury, it has become a mandatory 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.
Safety is influenced by various factors, for example, the quality of the rubber, the proper selection of seasonal car tires. In winter, it is necessary to use a special
studded rubber, prototypes of which appeared at the beginning of the last century in Scandinavia.
How to increase traffic safety with cyanoacrylate adhesive
To increase the stability of the car when moving on an icy (icy) road, bolts were installed in the through holes of the rubber, their fixation was carried out using nuts ("spikes"). Similar designs possessed considerable weight, were short-lived, unreliable. During its existence, winter tires underwent numerous changes, improved manufacturing technology.
When installing studs on winter tires, the press-in method is used (mechanical method). During operation, deformation of the rubber occurs, the geometry of the sockets intended for the installation of studs is violated. As a result, there is a high probability of thorns falling out, which will lead to a decrease in the quality of adhesion of the roadway with the wheels of the car, to an increase in the
braking distance. To increase the strength of the studs with the tread, winter rubber manufacturers use Permabond cyanoacrylate adhesive, a special adhesive.
Main characteristics
Cyanoacrylate second adhesive has the following specifications:
- excellent adhesion to metal and rubber;
- quick cure;
- wide range of working temperatures.
For example, Permabond c791 cyanoacrylate adhesive has all of the above characteristics, it can be used to install studs on car tires. It has a certain viscosity, therefore it fills all the free space between the connected surfaces, while not penetrating into the micropores of the tire, preventing excessive flow.
In practice, it was possible to prove that Permabond
cyanoacrylate adhesive allows to obtain 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 the spikes. It is enough to wait 10-15 seconds until the glue has completely cured.
Popular brand
Permabond C791 cyanoacrylate adhesive guarantees ultrafast and high-quality bonding of such materials:
- rubber;
- plastic;
- paper;
- metal;
- cardboard;
- leather;
- wood.
The composition is optimal if necessary to assemble small parts. Moment cyanoacrylate adhesive has a low viscosity, therefore, it easily penetrates into porous materials, increases the adhesion strength of glued surfaces. It is used in the manufacture of street lights, reliably protecting them from dust and excess moisture. For reliable sealing of
rubber seals and shades, cyanoacrylate glue is used.
Composition benefits
The main positive characteristics that distinguish glue cyanoacrylate from other types of glue:
- instant hardening;
- fast set of maximum strength;
- compatibility with various materials;
- simplicity of operation;
- lack of additional solvents.
How to use cyanoacrylate adhesive
Prior to the direct application of glue, the glued surfaces are thoroughly cleaned, dried, degreased. To improve the quality of bonding, you can use a special cleaner. Surfaces with a normal roughness will give a grip higher than primed or polished. In order to reduce curing time, in particular on inert surfaces, use Kernil cyanoacrylate adhesive. It is recognized as universal, with its help you can solve the most stringent conditions of assembly and production.
The principle of action of the composition
Permabond cyanocrylate adhesives are one-component modern adhesives that harden due to the interaction on the surface of the materials being joined with a small amount of moisture. The chemical formula of such adhesives was specially developed for the high-quality bonding of rubbers, plastics, metals, so a few seconds and room temperature are enough for the composition to fulfill its direct functional purpose.
Medium and low viscosity cyanocrylates
Such adhesives allow you to:
- perfectly stick together rubber, wood, plastic materials;
- combine rubber and metal, plastic and metal;
- protect 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 enhances adhesion. Priming is necessary to accelerate the curing time of the glue, as well as to fill the gaps at the bonded surfaces.
The main advantages of primers can be considered:
- accelerating the application of glue after surface treatment with a primer;
- bonding dissimilar materials;
- resistance to high temperatures;
- lack of smell, incombustibility;
- durability, reliability, corrosion resistance.
How to remove cyanoacrylate glue
Many people care about how to wash off cyanoacrylate glue. To do this, you can use special solvents or try the usual nail polish remover. It all depends on which surface you need to remove the composition from, so first you need to put a small amount of glue on the surface to check the reaction to the product, and only after that proceed to complete elimination.
Varieties of Permabond
Permabond manufacturers have developed many different adhesives to help securely fasten different parts. We list some of them:
- Permabond 735 is black in color and has improved impact and tear strength characteristics. With it, you can connect steel, aluminum, rubber, plastic.
- Permabond CSA accelerates hardening, 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 glued surfaces.
- Permabond 2010 is recognized as an ideal tool for joining porous surfaces, also suitable for joining inverted and vertical materials.
- Permabond 2011 does not spread, suitable for joining complex surfaces. In particular, it is perfect for curly sculpting from various materials or, for example, for restoring elements of kitchen utensils. Just imagine how ugly the smudge looks ugly on the just pasted favorite teapot. With this composition of his education, it will be easy to avoid.
- Permabond 4 C20 is a one-component, easily polymerized under pressure with the formation of a thin film between the joined parts. Designed for use on high-speed production lines to increase productivity. With it, you can glue 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 the usual PVA glue is suitable , then with complex restoration work it is impossible to do without cyanocrylate, because it reliably fixes the parts with the guarantee that they can perform their functions for a long time. The main task of the buyer is not to fall for a low-quality fake, since lately a lot of cheap substitutes are sold that are able to glue a couple of sheets of paper at most. In this case, we are not talking about any wood or metal. Buy the composition only in a trusted hardware store.
