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 ones, because it is he who interferes with the use in industry. As for Mastix cold welding, it withstands temperatures from -60 to + 150 ˚C and above. This is an excellent performance compared to the competition.
The material is used to connect different elements, as it is based on components with higher qualities than standard types of glue. If you follow the application rules, you will ensure a quality connection of broken parts or elements of a new design.
Things to consider
The main feature of the use here is the ability to connect lost parts and create new designs. With cold weldingMastix you can repair cracks, chips and holes, as well as eliminate other defects. In domestic pipelines, the temperature usually does not exceed the permissible temperature, which applies even to those systems that are designed to transport hot water.
Form of issue and methods of application
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 weld dries gradually after application and forms a hardened masonry patch or solid joint.
Main benefits
The adhesive described is a general purpose cold weld that can bond almost any surface better than if you were using another type of adhesive. On sale you can find several varieties that have the best properties. This should include cold welding for:
- aluminum;
- plastic;
- metal.
You can also purchase a universal remedy. Mastix cold welding is also good because it is easy to prepare and use. This does 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-piece rod. It should be noted inas a plus, a fairly wide operating temperature range.
The main cons of welding
Before you purchase cold welding, you should consider not only its pros, but also its cons. Among the latter, the drying time should be highlighted, which is somewhat 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 rework.
Uses
Mastix glue - cold welding, which is used not only at home, but also when carrying out repair procedures in the industry. Everything will depend on the type of material. It is commonly used as a regular adhesive that bonds different materials - stone, plastic, wood and metals. As a rule, they are difficult to bond with other compounds.
A rather important function is the ability to repair pipelines, car parts, various containers and other things. The plastic mass is applied to the cracks, the composition penetrates inside. Universal cold welding Mastix should not be operated at temperatures above + 150 ˚С. Under suitable conditions, the material can be used to repair items that are chipped.
In the process of work, 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 thatwithstand impressive shocks, but vibration loads are transferred normally. They are often found in moving mechanisms.
Composition
Cold welding for Mastix batteries consists of:
- mineral fillers;
- amino acids;
- metal fillers;
- epoxy.
The mixture contains a metal filler that improves the quality of the connection. The glue tolerates contact with moisture well, so it can be used for plumbing repairs. The mixture does not have a high sensitivity to surface cleanliness, so it can be used with oily parts and wet surfaces.
Additional information about the composition
The welding composition is multi-component. The basis is an epoxy polymer. To increase the resistance of the epoxy polymer to shock, mechanical stress and vibration, plasticizers are used. 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 changes. The hardener can be stone or polyamide. It is necessary to stimulate the hardening of the composition. A thin layer at the same time hardens within only a few minutes.
Reviews on universal, heat-resistant and plumbing cold welding
Mastix cold weld reviews will let you know which composition to give preference to. If in front of youuniversal mixture, then you should know about its purpose. It is suitable for quick surface repairs and has a wide operating temperature range. This glue option 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 ˚С. Glue can be used to connect non-ferrous, ferrous metals in thermally active spheres. On sale you can find plumbing adhesive for working in wet conditions. Consumers are advised to use the composition when repairing plumbing, which will be operated in conditions of high humidity. The adhesive is able to withstand working under pressure. It can be used to connect porcelain, metal and restore threads.
Cold welding for metal Mastix, according to consumers, has a steel filler in its composition, which can improve the quality of the connection. If you need to join aluminum parts, you should purchase a Mastix with the appropriate properties, which has an aluminum filler. This makes the connections stronger.
Instructions for use
After studying the Mastix cold welding instructions, you can find out that the composition should be stored at temperatures up to +30 ˚С. The maximum working temperature reaches +200 ˚С or more, depending on the type of mixture. The minimum operating temperature in all cases is -60 ˚С. The package contains 55 g of the mixture.
At the initial stage, the surface is protected. Even if the packaging indicates that this step can be neglected, and the gluesuggests the possibility of use on an oily surface, for a better connection everything should be cleaned. After that, the part that you plan to use is cut off from the total mass. Both components must be in equal quantities. Then you need to knead the mixture and apply it to the surface. The next step will be waiting for 20 minutes. The maximum period is an hour for everything to grab well.
Specialist recommendations
When mixing the mass, you must achieve its homogeneous pasty consistency. The mass is applied to the surface, the parts to be joined are fixed. The final connection should be expected in three hours. Cold welding can be stored for two years.
If used correctly, this remedy will be safe for human he alth. When using the material, you must be careful that it does not come into contact with human mucous membranes. Wear rubber gloves first to protect your hands.
In conclusion
If you need to repair defects in pipes or connect parts that will be used under difficult conditions, cold welding is for you. But before buying, you need to study its varieties in order to make the right choice.
