Choosing a universal glue: what to look for?

When choosing cold welding, in addition to the brand and price, the following parameters are important:

Type of bonded surface.

There are universal adhesives for metal, linoleum and rubber, plastic and concrete. Moreover, the composition allows you to combine materials in any combination, combining into one whole, for example, concrete and wood, rubber and plastic, steel and glass.

Vibration resistance.

Cold metal welding withstands vibration loads, is resistant to aggressive environments and temperature changes. Successfully restores the tightness of radiators, tanks and fuel lines, oil pans and other elements.

Tear resistance.

Restoration of components operating under physical load using universal glue allows the connection to withstand forces of up to 200 N*m. Such welding is indispensable for emergency repair of a car suspension, as it will allow you to independently eliminate the malfunction (broken lever, rod, etc.) and get to a service center or garage without the help of a tow truck.

Heat resistance.

A special type of cold welding that can withstand heating up to 150-250˚C. It is successfully used to restore car mufflers, highways and heating system equipment.

Moisture resistance.

Adhesives of this group are impervious to moisture, and in some cases can be applied even to a wet surface, maintaining high adhesion to it.

Hardening time.

Since cold welding is often used for emergency repairs, setting time is important. The smaller it is, the better.

Types of glue for metal

There are two main types of metal adhesives: one-component and two-component.

One-component adhesives have a small number of applications. They do not tolerate low temperatures well, so they cannot be used at temperatures below +5 degrees.

For industrial use, such glue is sold in aluminum tubes, which allows the mixture to remain capable of reliable bonding for a long time.

Two-component adhesives have a much wider range of applications.
They are capable of gluing metal to various surfaces.
Two-component adhesives are used in various fields: In industry, construction, and everyday life.
After hardening, the mixture retains its plasticity, but at the same time becomes very strong and reliably holds the glued surfaces.

You can also divide adhesives into groups according to the duration of hardening. Here it is customary to distinguish between fast and slow drying adhesives.

Eliminates emergency leaks without drying Thanks to its high adhesive ability, the universal cold welding “Contact” can quickly eliminate a leak in a pipe, oil pan or gas tank without first drying the damaged area.

Characteristics
Average price: 239 rub.
Country Russia
Weight: 50 g
Curing time: 180 min.
Temperature resistance: -40…+150˚C
Number of components: 2

The universal adhesive has proven itself excellent in restoration and gluing of various metals, glass, ceramics, plastic, and wood. Easily takes a given shape and sets quickly. For cold welding, stopping a leak in a water pipe or gas tank is not a problem. At the same time, the glue performs its task by working with a wet surface. Due to its high adhesion, “Contact” perfectly seals the most inaccessible places. The plasticity of the compound prepared for work decreases sharply after 3-5 minutes, so you need to work with it quickly. Treating the base during application (cleaning and degreasing) increases the reliability of the connection, however, during emergency repairs this is not always convenient.

Advantages and disadvantages

Hardens quickly
High adhesion
Solvent resistance

Foundation preparation required

Where is this technology applicable?

Essentially, this product is glue. It is very strong, suitable for repairing cast iron pipes or water pipes. In many situations, cold welding is even used to repair a machine, for example, if there are any breakdowns or cracks in the engine area . In addition, it is suitable for working not only with metals, but also with plastics, glass, ceramics and wood. Also, users on the network indicated that with the help of this welding it is possible to further increase the missing parts of the product.

Of course, welding metal will actually be much more reliable than gluing it together.
But cold welding pays off in emergency situations. Many motorists share on forums their experience of repairing minor car breakdowns. Someone sealed the holes in the fuel tank, someone had to repair the radiator tank using cold welding .
There are plenty of other similar reviews. This glue may not completely solve problems with metal breakdowns, but it will help in cases where a welding machine is not at hand. If you need to repair a hole in a hard-to-reach place, it will be easier to use cold welding.

I repaired the fuel tank underneath. It takes a long time to remove it from the car, steam it, and then solder it, and it’s very inconvenient. He climbed in and looked - and there was a very thin hole, as if it had been pierced with a needle, the stream was like from a syringe. Friends said that cold welding would not hold up. I didn’t listen and smeared it right over the running gasoline. After that I drove quietly until I parted with the car and sold it.

Criterias of choice

There is no single answer to the question of which cold welding is best for metal, because there are no ideal compositions. When choosing, you need to pay attention to the following factors:

First of all, you need to study the composition. In order for the seam between metal parts to be as strong as possible, the structure of the epoxy resin must be more uniform.
When using gluing on high-temperature devices, you need to see what temperatures the product can withstand after hardening. The seam will lose its strength when heated above the permissible temperature.
Freezing time. If you need to carry out quick repair work, it is important to buy quick-hardening glue.

Advantages of cold welding

Any method of connecting parts has both strengths and weaknesses. Advantages of cold welding:

Reliability of connections.
No electricity or gas costs.
There is no additional training required to use cold welding.
The application process takes place using improvised means.
When used correctly and with a high-quality composition, the finished seam is stronger than the material being glued.
Fast hardening. You can start using the glued part after 2-3 hours.
No waste after use.

Unlike hot welding, cold welding does not expose the item to heat and subsequent destruction.

How to use metal glue

Before starting the gluing process, it is necessary to carefully prepare the surfaces to be glued. Particular attention should be paid to metal. It needs to be thoroughly cleaned and all traces of corrosion removed.

In this case, it is undesirable to use any solvents, since they can leave a layer of additives on the metal surface that interferes with strong bonding.

After preparing the surfaces, you can start preparing the glue.
When using two-component glue, it is necessary to prepare a container in which both components will be thoroughly mixed.
Then the resulting mixture should be applied to the surfaces to be bonded.
The amount of glue is taken in accordance with the instructions.
After applying the adhesive, the surfaces should be pressed firmly against each other, or even put under a press.

You can increase the strength of the connection using a special substance - a primer. Treating surfaces with a primer degreases them well, which increases adhesion.

Recommendations for use

Despite the fact that the process of using cold welding is quite simple, you should still know some of the features of its use.

Drying period

It is different for each type and even for each brand, but it usually dries completely within 24 hours. However, there is also such a concept as “pre-drying” - it means that the substance has already created the final form, is no longer susceptible to deformation, but has not yet achieved a stable connection with the processed object. In this position, the applied seam is still vulnerable, so you should not subject the treated object to unnecessary stress. “Pre-drying” usually occurs in the first 5-20 minutes after application, so this period is quite enough for the user to form the seam itself. Some brands of cold welding reach final drying in half a day, but professionals recommend starting to use the glued object only after 24 hours.

Precautionary measures

At first glance, cold welding itself may seem like a harmless composition, but certain safety measures must be observed when working with it:

It is preferable to work in protective glasses and gloves - do not allow the composition to come into contact with exposed skin or eyes. In the event of a traumatic situation, you need to rinse the damaged area of the body with clean water and immediately consult a doctor;
The adhesive mass should be stored out of the reach of children and pets;
Cold welding particles should not be allowed to come into contact with food.

Typical errors during operation

These primarily include:

Inattention to the expiration date - an expired expiration date will cause poor-quality sutures;
Surface preparation contrary to the recommendations of the welding manufacturer - the welding seam may simply fall off;
Unsealed storage of the adhesive composition - the composition will simply harden and will not be suitable for use (for plastic compositions it is possible to heat them in warm water, but this will reduce the quality of the seam);
Use of the composition for other purposes – use of the composition for welding materials for which it is not intended;
The use of the composition without taking into account the conditions of future operation - if we are talking about the operation of a repaired object under conditions of elevated temperature background, then the welding applied to it must be heat-resistant;
Failure to comply with proportions when mixing liquid compositions - incorrect adherence to proportions can lead to an almost complete lack of adhesion (adhesion) for these compositions.

Top 5. Linocol Bostik

Rating (2021): 4.07

Best hardening speed Cold welding for PVC Linocol Bostik hardens within a minute after application - this is the best indicator in the rating.

Characteristics
Average price: 290 rub.
Country: France
Weight: 60 g
Curing time: 1 min.
Temperature resistance: +5…+35˚C
Number of components: 1

One-component cold welding for rubber and polyvinyl chloride products (pipes, linoleum, etc.) reacts with the surface being treated and transforms the joint into a homogeneous area within one minute. Polymerization of the seam eliminates the passage of moisture - this is one of the best compounds for sealing and connecting PVC pipelines. A convenient needle attachment for careful application is very useful - if glue gets on the decorative surface of the linoleum, it will not be possible to remove it. After a quarter of an hour, the treated area is ready for work. Among the shortcomings, the owners indicate only a pungent odor (disappears after hardening) and the high cost of Linokol.

Advantages and disadvantages

Best setting speed
Moisture resistance

Strong odor before drying

How to work?

The application site is thoroughly cleaned and degreased. The surface will become rough after using coarse sandpaper.
To prevent the composition from sticking to your hands, it is recommended to moisten them with water.
Before starting work, carefully study the instructions. Pay special attention to the temperature conditions and drying time of the glue.
Squeeze the substance into a prepared container in a 1:1 ratio. Mix until the mixture is homogeneous in color and viscosity.
Cover both surfaces to be treated with glue and press. Remove excess with a cloth soaked in acetone.
The part should be at rest for 5 to 60 minutes (primary drying time).
The product will dry completely in 12 - 24 hours.
