Cold welding Mastix: how to apply glue? Characteristics, advantages and disadvantages

There are many options for cold welding products on the market. But not all of them can be useful under large temperature changes. That is why their use in industrial conditions becomes impossible. Mastix's new generation cold welding is far ahead of its competitors in this aspect. It can withstand temperatures from -60 to +150 degrees Celsius. It can be used to connect any objects from any material, since its quality is much higher than that of ordinary glue.

If you strictly follow all the rules, it can be used to effectively connect both broken things and new parts that have not been installed before. But, in addition, cold welding has another important feature - it becomes possible to form lost particles or new elements of parts. Using Mastix cold welding, the master has the opportunity to fill holes, cracks and other damage with it.

Household pipes (even if they are filled with hot water) do not have too high a temperature, which makes it possible to use this type of glue. Welding is supplied by an element that looks like a rod. It combines two components. The first of them is inside, the second is the outer shell. In order to start using them, you just need to mix the composition. The resulting mixture will have a soft shape. This state can last up to seven minutes. After this time, it will begin to dry out little by little until it completely turns into a solid state.

Characteristics

Mastix welding includes the following components:

Epoxy base.
Plasticizers.
Fillers.
Hardener.

Epoxy polymer is the adhesive base of the cold welding composition.

Plasticizers are designed to increase the resistance of cold welding to mechanical stress, such as shock or vibration.

Fillers are powders of metal and minerals . They are designed to improve Mastix's thermal conductivity and strength properties. Such components make cold welding more resistant to temperature changes.

The hardener (polyamine or amine) is designed to increase the rate of hardening of the composition . Thanks to its action, the product can turn into a solid substance within a few minutes.

Mastix Welding is typically available as a two-piece rod.

The main characteristics of the standard Mastix packaging are shown in the table.

This cold welding works over a wide temperature range.

What are the disadvantages of Mastix?

Takes longer to dry than other adhesives, so may be uncomfortable in some temperatures;
If, after preparing the mixture for work, lumps form, the quality of work will be reduced (because of this, there is a need for rework).

Peculiarities

The manufacturer Mastix offers a wide range of weldings of this type. Depending on the purpose of a particular type of welding, its composition changes.

Thus, for welding metal products (for example, welding pipelines and plumbing), a modification is proposed that uses a metal filler. This composition ensures high strength and durability of the seam. In addition, this type of welding makes it possible to create a seam on wet surfaces.

For welding parts made of various metals, Mastix is produced, which has special compositions. For example, for welding steel parts, the “Fast Steel” welding type is produced. It contains steel filler. For welding aluminum products, a composition is proposed that includes an aluminum filler.

Mastix has a special composition, which is designed to work at elevated temperatures. This mixture has a red wrapper and can work at temperatures reaching +250 °C.

Cold welds intended for plumbing repairs can hold metal and porcelain together well. Such weldings are characterized by durability and the ability to resist moisture penetration.

Advantages and disadvantages

Main advantages of Mastix:

allows you to qualitatively connect parts from different materials;
Available in various modifications with improved characteristics for welding specific materials;
ease of use (no special skills or additional training required);
Available for use in different temperature conditions;
low cost.

Flaws:

relatively long hardening time (6-7 minutes). This drawback may affect when carrying out urgent work;
When preparing the mixture, lumps often form , which can impair the quality of welding.

Areas of use

Depending on the composition of the Mastix cold welding modification, it can be used to connect:

parts and products made of metal (steel, aluminum);
metal and non-metal parts;
metal products operating at high temperatures (up to +200 degrees);
sanitary ware, tile products, porcelain, marble.

Along with gluing, Mastix can be used to seal chips and cracks. The frozen mixture will not be able to withstand large mechanical loads, but it can be used to repair moving mechanisms. For example, cars.

In the household, this product can also be used to repair furniture, interior items and household utensils.

Varieties

produces several types of cold welding under one brand.

“Universal Blitz” glue is the most popular mixture. Used for gluing any materials: “Takes” everything: cast iron, steel, non-ferrous metals, ceramics, glass, rubber, plastic, soft and dense wood. The connection can withstand heating up to +200°C. Reviews about the glue are only positive.
Universal glue is slightly inferior to Blitz universal in terms of heat resistance; it works in the temperature range from -60°C to +150°C. Characterized by rapid polymerization.
Heat-resistant cold welding is recognizable by its bright red packaging. Retains adhesive properties when heated to +250°C.

Types of cold welding Mastix
Specialized compositions for narrow areas of use are available for sale:

Mastix for plumbing is not afraid of high humidity; it contains alcohol, which binds to excess moisture. Used to eliminate leaks in utility lines and process pipelines. Turns white after polymerization, suitable for repairing sanitaryware.
“Fast Steel” contains a large proportion of metal powder and is good at restoring lost fragments and chips on cast iron. Used for joining all types of steels.
The mixture for aluminum products also contains metal powder, aluminum. Ideally connects difficult-to-weld duralumin alloys.

How to apply

To carry out a cold welding operation, you must prepare:

Mastix welding compound.
Abrasive material (sandpaper).
Solvent.
Clamp.
Latex gloves.

Some types of Mastix allow you to glue parts without cleaning them from dirt and moisture. But it must be taken into account that in this case the strength of the seam deteriorates by 20-30%. Therefore, before cold welding, the surfaces of the parts must be properly prepared.

Cold welding algorithm:

Clean the connecting surfaces of the parts from scale, rust and other contaminants.
Degrease surfaces.
Unwrap the Mastix and peel off the stem piece . When determining the size of a piece of the mixture, it is necessary to take into account the initial hardening time (6-7 minutes).
Put rubber gloves on your hands, wet your fingers with water and knead a piece of the mixture well . When mixed correctly, the shade of the mass will be uniform, without lumps or inclusions.
Apply the mixture to the surfaces to be joined and connect them . To eliminate the hole, it is desirable that part of the mass gets inside it.
Secure the connection mechanically.
Maintain fixation for 15-18 minutes . Complete hardening of the material occurs within 1 hour to 24 hours.
If you need to make a second layer, then before applying it you must wait until the first layer has completely hardened , which should not exceed 6 mm.

Instructions for use

Before starting work, you must study the instructions for use from the manufacturer of cold welding Mastix. Work must be carried out in the following sequence:

First, the working surfaces are prepared: cleaning from scale, traces of rust and other contaminants. Surfaces need to be wiped, dried, degreased (if possible).
At the second stage, you need to separate a third of the rod and mix the components with rubber gloves soaked in water. Proper mixing will be indicated by the shade of the mixture: uniform, without lumps, noticeable inclusions, or streaks.
At the third stage, the resulting mixture must be applied to the two surfaces to be joined, connected to each other, and secured.
The duration of fixing parts is 15-18 minutes.

If the surfaces are dirty, oiled, or moistened, then the strength characteristics of the resulting joint are reduced by approximately 20-30%. This is when compared with prepared and clean surfaces.

If work is carried out in conditions of negative temperatures, then during the preparation process, warm the mixture in your hands for several minutes. Be sure to store in a warm room before using in the cold.

By the way, according to my observations, all tubes contain generalized instructions. Which contains recommendations separately for all types of Mastix brand glue.

What to remember

Mastix contains epoxy and amine resins, which are toxic and hazardous to human health.

Therefore, when using cold welding, the following must be considered:

Do not use to repair utensils in which food is prepared or stored..
Keep out of reach of small children.
Avoid contact of the mixture with skin and use rubber gloves.
If glue gets on your skin, wash the area of contact with soap and water or wipe it with alcohol.
If crumbs of the mixture get into the eye, rinse the eye and seek help from a doctor.
It is advisable to carry out work with cold welding in a room with ventilation , since during polymerization the epoxy resin included in Mastix emits harmful fumes.
When sanding a frozen seam, goggles and a respirator must be used to protect the respiratory tract and eyes from the resulting dust..
