Almost all faced with various damages to plastic or metal products in their lives. Many simply changed this or that detail, but not everyone has the opportunity in an emergency to replace a whole unit. For example, when a battery leaks, you should not buy a new one when you can simply brew it. And if there is no way to call a welder? For such cases, there is a special glue. People simply call it: cold welding for plastic and metal.
What is cold welding?
This is one of the ways to connect parts from various materials without heating, at room or even negative temperature. For use, it is enough to just apply the product on mating surfaces, then create pressure and wait a bit. The result is an almost monolithic and high-strength compound.
Cold welding can be used both for metal products and for various polymer parts. For example, various metals, such as aluminum, copper, zinc, silver, iron and others, can be glued with this glue. Such glue is convenient and indispensable if it is necessary to connect dissimilar materials. For example, cold welding for plastic perfectly connects plastic pipes without a soldering iron.
What does it consist of?
This glue is based on a special epoxy resin. Most of the products that are sold in our stores have a two-component basis. To make the glue effective, the use of resin alone is not enough. Therefore, the so-called hardener is used. If you mix the two components, then this glue will quickly turn into an unusually solid state. This property is the basis of it.
The epoxy itself does not have strength. It very poorly withstands various loads, so manufacturers use the so-called plasticizer together with the resin. It should increase its elasticity. The filler is needed in order to give the composition special properties, such as thermal conductivity, heat capacity, as well as abrasiveness. In order for cold welding for plastic to have these characteristics, metal-based elements are added.
Sometimes on sale you can find already completely ready-to-use mixtures, and sometimes glue and hardener need to be mixed manually, in compliance with the exact dosage.
The main advantage is that for such a fastening of parts, no additional steps are necessary. You can get a quality connection without the use of presses, electrical appliances or the help of professionals in these works.
Glue for plastic
The processes of connecting parts by welding have long been indispensable in human life. The glue method of joining, which is not inferior in strength to welding work, is a real technological breakthrough. It does not require large investments and a long time to work.
Glue (cold welding) for plastic is an inexpensive and easy way to qualitatively connect various parts without heating. The connection is obtained due to the chemical processes that occur when plastic and adhesive are in contact.
This technology allows you to not violate the properties of the materials being joined. This is true when connecting various electrical wires and insulation. Thanks to this method, you can safely perform work.
A similar method of connection is widely used for various technical and industrial purposes, in construction work and, of course, in everyday life. Cold welding for plastic is a unique and versatile product. Another advantage of it is non-waste.
Thanks to this method, good tightness can be obtained for the housings. Motorists found this very useful.
Where to use cold welding?
For plastic products, there is a separate variety of such compounds. The main scope of use:
- Repair or puttying of bumpers in cars.
- Repair household items.
- Strong connection of various plastic products.
- Repair of various devices or parts.
- Reconstruction work with plastic pipes.
Cold welding for plastic: instructions for use
Typically, instructions for using these products are indicated on the packaging. Manufacturers describe how to use the tool, what safety rules must be observed when working with such a product. But let's see how to use this glue.
First of all, you need to prepare the surfaces that you want to join. To do this, you need to process them with sandpaper. Next, degrease the joined surfaces. For this, alcohol or any other alcohol-containing liquids are suitable. The degreasing process is a very important procedure. Now you need to choose the right size piece of bonding material. Then you need to stretch a piece of glue in the fingers. To do this, wear gloves and fingers should be moistened first. You will realize that the glue is ready when it resembles plasticine.
Next, apply the substance to the parts that need to be connected, and then fix them with a clamp. If you have to connect the pipes, you will need a special harness. After the tool has hardened, and it takes about an hour to do this, you can do anything with it, even drill and thread. For example, cold welding for plastic "Titan" allows you to get a particularly strong connection, not only on materials from various plastics.
Safety precautions
Any work must be carried out with the proper level of security. The use of such substances can be harmful to your health if used incorrectly.
Inadmissibility of the mixture on the skin or in the eyes. It is not recommended to leave the product in the sun. Work must be carried out with glasses and gloves.
Cold welding for plastic: reviews
Let's see what real people say about this glue, who have tested all its advantages on themselves. Many of them - motorists, motorcycle owners, cyclists and ordinary people who urgently needed to fix something.
Many people write that they use this glue regularly. Reviews say that this is the easiest and cheapest way to fix a leaking pipe, a means to seal the crankcase or gas tank in a car. Also, many with the help of cold welding were able to fix the plastic water pipe.
Conclusion
It turns out that cold welding for plastic is a really inexpensive, reliable and universal way of sealing and creating a strong connection of parts from a wide variety of materials.
