Among the materials for cold welding on the market, there are not many that are able to work in a wide temperature range. This drawback is one of the main, because it is precisely it that interferes with use in industry. As for Mastix cold welding, it can withstand temperatures from -60 to + 150 ° C and above. This is an excellent indicator compared to competitors.
The material is used to connect different elements, since the basis is components with higher qualities than standard types of glue. If you adhere to the rules of application, then ensure a quality connection of broken parts or elements of a new design.
What is important to consider
The main feature of the use here is the ability to connect the lost parts and create new designs. Using Mastix cold welding, you can repair cracks, chips and holes, as well as eliminate other defects. In domestic pipelines, the temperature usually does not exceed the permissible limit, even for those systems that are designed to transport hot water.
Release form and methods of application
The glue is supplied in the form of a rod in which two components are connected. The first is located inside, the second is the outer shell. Before use, the ingredients are mixed, as a result of which it is possible to obtain a soft composition that retains plasticity for 7 minutes. Mastix cold welding gradually dries after application and forms a hardened masonry or solid joint.
Main advantages
The described adhesive is a universal cold welding, with which you can glue almost any surface more qualitatively than if you were using a different type of adhesive. On sale you can find several varieties that have the best properties. This should include cold welding for:
You can purchase a universal remedy. Mastix cold welding is also good because it is easy to prepare and use. This will not require special experience or special knowledge. The material is inexpensive and available at retail outlets. It has a convenient delivery option and is offered as a two-component rod. It should be noted as a plus also a fairly wide range of operating temperatures.
The main disadvantages of welding
Before you get cold welding, you should consider not only its advantages, but also the disadvantages. Among the latter, it is necessary to highlight the drying time, which is slightly higher than that of other brands. In this regard, some problems may arise when working with different temperatures. The preparatory phase may be accompanied by the formation of lumps, which reduces the quality of the connection and leads to the need for alteration.
Application methods
Mastix glue - cold welding, which is used not only at home, but also during repair procedures in industry. Everything will depend on the type of material. Usually it is used as ordinary glue, which combines different materials - stone, plastic, wood and metals. As a rule, they are difficult to glue with other compounds.
A rather important function is the ability to repair pipelines, car parts, different containers and more. The plastic mass is applied to the cracks, the composition penetrates inside. Mastix universal cold welding should not be operated at temperatures above + 150 ° C. Under suitable conditions, the material can be used to repair products that have chips.
In the process, it is important to withstand the time during which the mixture dries, after which the part is put into operation. The properties of the fortress are not so strong as to withstand impressive shocks, but the vibration loads are tolerated normally. They are often found in movable mechanisms.
Composition
Cold welding for Mastix batteries consists of:
- mineral fillers;
- amino acids;
- metal fillers;
- epoxy resin.
The mixture contains a metal filler, which improves the quality of the connection. The glue tolerates contact with moisture well, therefore, it can also be used for plumbing repairs. The mixture does not have a high sensitivity to surface cleanliness, so it can be used with oil parts and wet surfaces.
Additionally about the composition
The composition of the weld is multicomponent. The basis is an epoxy polymer. Plasticizers are used to increase the resistance of the epoxy polymer to shock, mechanical stress and vibration. Fillers are metal and mineral components. They allow you to increase the thermal conductivity of the mixture, improve strength, which makes the connection resistant to temperature extremes. The hardener may be stone or polyamide. It is necessary to stimulate the hardening of the composition. In this case, a thin layer hardens in just a few minutes.
Reviews on universal, heat-resistant and plumbing cold welding
Mastix cold welding reviews will let you know which composition you prefer. If in front of you is a universal mixture, then you should know about its purpose. It is suitable for quick surface repairs and has a wide range of operating temperatures. This type of glue is the most used and popular.
Consumers emphasize that heat-resistant welding is able to withstand high temperatures, and its operation is possible up to +250 ˚. It is possible to use glue for joining non-ferrous, ferrous metals in thermally active spheres. On sale you can find sanitary glue for working in wet conditions. Consumers are advised to use the composition in the repair of plumbing, which will be operated in high humidity. The glue is able to withstand work under pressure. With it, you can combine porcelain, metal and restore the thread.
Cold welding for Mastix metal, according to consumers, has a steel filler in its composition, which can improve the quality of the connection. If you need to connect aluminum parts, you should purchase Mastix with the appropriate properties, in which there is an aluminum filler. Thanks to this, the compounds are stronger.
Instruction for use
Having studied the instructions for Mastix cold welding, you can find out that the composition should be stored at temperatures up to +30 ˚. The maximum working temperature reaches +200 ˚ or more, depending on the type of mixture. The minimum working temperature in all cases is -60 ˚. In the package - 55 g of the mixture.
At the initial stage, the surface is protected. Even if the package indicates that this step can be neglected, and the glue suggests the possibility of using it on an oily surface, everything should be cleaned for better bonding. After that, the part that you plan to use is cut off from the total mass. Both components must be in equal amounts. Then you need to knead the mixture and apply it to the surface. The next step is to wait for 20 minutes. The maximum period is an hour, so that everything is well grasped.
Specialist recommendations
When mixing the mass, you should achieve its homogeneous pasty consistency. The mass is applied to the surface, the parts to be joined are fixed. Final connection should be expected in three hours. Cold welding can be stored for two years.
If used correctly, it will be safe for human health. When using the material you must be careful, it should not come into contact with the mucous membranes of a person. Rubber gloves should be worn first so you can protect your skin.
Finally
If you need to eliminate defects in pipes or connect parts that will be used under difficult conditions, cold welding is suitable for you. But before buying, you need to study its varieties in order to make the right choice.
