Future operating conditions should be considered when selecting a product to ensure the dependability of the metal-to-metal or other material connection. For instance, the material ought to be heat- or waterproof-resistant.

It’s also important to consider:

  • for a term, conditions for hardening;
  • maximum, minimum temperature at which glue retains properties;
  • The method of application to the surface is point or continuous;
  • type, glue shape (liquid, pasty, one or two -component);
  • the maximum suture stress, its elasticity.

Moreover, surfaces with glue are considered. Mixtures that work for everyone won’t be the best option. For the specified targets, a specific glue must be used.

The composition’s increased viscosity broadens its application.

Glue requirements

  1. The strength of the hardened layer.
  2. Temperature jumps.
  3. Environmental friendliness.
  4. Minimum chemical composition and smell.
  5. Long shelf life and strength of fixation.
  6. Minimum shrinkage and expansion after drying.
  7. Anti -corrosion protection of metal.

Types of metal adhesives

One- and two-component epoxy adhesives are the most widely used types.

  • One -component Immediately ready to apply.
  • Two -component requires breeding before use. The resin is mixed with hardener and applied to the surface.

Epoxy is a pasty, liquid substance.

The second choice looks like a block of plasticine that has been applied to metal or another base and kneaded with fingers.

The hardening of adhesives happens slowly but quickly.

A picopol is an illustration of an epoxy mixture. made up of two tubes.

Adhesives based on plastic and acetone are available. harden as a result of the solvent evaporating. Not appropriate for heated surfaces.

Thermic mushrooms, which are produced as rods, are actively used in needlework. As they refuel in the adhesive gun, the high temperature causes them to melt. The thermal pistol’s nozzle applies molten rod to iron when the trigger is pulled.

For a strong, long-lasting bond when gluing metal to metal, selecting the appropriate adhesive is essential. This post will walk you through the top brands on the market, emphasizing their special qualities and benefits. Whether you require an adhesive for demanding industrial applications or a dependable fix for home repairs, we’ll discuss the best options that provide outstanding functionality and user-friendliness. We’ll assist you in selecting the ideal glue, such as Loctite or J-B Weld, to make sure your metal components adhere firmly and endure over time.



Glue hardens quickly, is waterproof, and resistant to heat. withstands freezing temperatures, is waterproof, and resistant to moisture. It thrives on a variety of surfaces. has a gray hue that renders it undetectable on metal.

The primary component and hardener are contained in two tubes in the Poksipol packaging. Apply the mixture, diluted one to one, right away to the metal foundation.

Ten minutes later, the layer hardens. The part can be applied by machining—drill, cut, and saw—in an hour. Complete polymerization, however, takes a full day.

Poxipol is cheap, but it’s not perfect:

  • poorly connects the subtle bases of the VSTOK;
  • Due to the thick form, only with a thick layer is applied.

Weicon VA 110

The NSF certification attests to the composition’s official environmental friendliness.

  • Glue is moisture -resistant;
  • operation temperature -30 -+80 ° C;
  • Due to the Cyanacrylate, which is called superhlome-polymerization from 20 to 50 s;
  • maximum strength in a day;
  • Shear strength – up to 20 N per mm 2 after sandblasting;
  • without color, completely transparent;
  • In addition to metal, glues plastic, rubber, rubber and others;
  • can be used for metal utensils that contacts food.

The composition is pricey; 60 g of funds will set you back more than 3,000 rubles, while a 12-gram tube will set you back slightly more.

Strong Steel Stick Renewal Composite 114

Its adhesion is high and its polymerization happens quickly (20 minutes). Epoxy resins are central to this. The structure is flexible and simple to use. It resembles a rod made of plasticine. It is worked into the paste using your hands.

It becomes resistant to loads, chemicals, salts, alkalis, acids, and solvents after polymerization.

Excellent for patching pipes. The Russian market is difficult to access and is not inexpensive. possesses flaws comparable to puxypol.

Weicon RK-1500

Metal adhesive composition consisting of two components. joins aluminum, steel, iron, and other alloys. securely fastens thin metal sheets in the water.

  • Suitable for plastic, ceramics.
  • The glue can be called high -temperature: it is operated from -50 to +130 ° C, and overheating is allowed up to 180 ° C for a short time.
  • Gap strength after drying to 26 N per sq. mm.
  • 5 minutes after processing, the adhesive compound reaches its original strength.
  • The activator can be added from one or two sides to the main component. This depends on the thickness of the applied layer – from 0.4 mm to 0.8 mm.
  • Apply the activator carefully. Due to the too liquid consistency, it can spread.
  • It glues even different in structure of the base, adhesion between which is minimal, for example, metal with glass, other smooth bases.


Is a better version of the traditional epoxy EDP. There has been a change in the hardening time (3 hours), the thermal resistance (120 ° C), and the ability to operate in heated conditions. When moisturizing, EPOXIMAXX does not alter the properties. The gap has a strength of 60–80 MPa.

Since consistency is liquid, applying with a brush is feasible. Suggested for applying adhesive to sizable regions, not a lot. It is reasonably priced.

Bison Super Glue Gel

Superglue like this is used for little home repairs. universal and adaptable to many materials. Its gel-like consistency makes it easier to use and keeps it from spreading.

  • Solds in one or two minutes, which allows you to adjust the position of parts after fastening, reduce the risks of gluing the fingers, as in the case of a conventional superglide.
  • Smearing on metal, small cracks are filled with glue. pores, which increases the reliability of the coupling.
  • There are only 3 g of substance in the tube, enough only for small work.

Heat -resistant glue type "300"

Withstands 1000 degrees Celsius in temperature. The border at the bottom is 300 degrees. Even when exposed to high temperatures for an extended period of time, the components do not degrade or change in properties. utilized in heating appliances such as furnaces.

When two dissimilar materials, like brick and metal, are adhered to one another, they ought to be thermally resistant.

A composition with low toxicity is chosen for internal use.

Certain manufacturers supplement their compounding strength composition with refractory clay or an element for reinforcement.

  • The famous brand is the Russian D-3142. Sticks tiles of ceramics on a metal basis of furnaces equipment. Withstands heating up to 850 ° C for a long time.
  • The moment epoxily . Produced by the German company Henkel. Epoxy is taken as a basis. Gluing iron, ceramic and other fragile bases.

Double-sided tape

Industrial double-sided tape needs to be compressed and sandwiched between two surfaces. Adhesive tape is primarily made of polypropylene or a foamed base, to which an adhesive layer is applied on both sides.

  • Metal Shelf Tape;
  • Dublkote;
  • Dublfix

How to glue it correctly

The metal’s surface is free of any signs of rust, spots, dust, and grime. Using gasoline or solvents is not advised. Primers are a good way to increase adhesion during initial processing.

The glue is ready. If it is a two-component mixture, the proper ratios are used to combine the two ingredients. When applied to iron, both bases are clamped in a vice, fit under the press, or pressed up against one another.

Using a spatula or plate, mix and apply epoxy is done. It is frequently fastened to the container.

Gluing techniques vary based on the type of seam that needs to be achieved.

  1. Static hard gluing. It is used for structures that will not be subjected to high mechanical loads or expand (narrow) with changes in temperature.
  2. Deformation gluing. On the contrary, it is used to create an elastic connection on structures subject to regular loads. For example, stairs, cars of cars, racks, signs and others. Suitable for fixing metals with different linear expansion coefficients when heating or cooling.

Epoxy works well for both of these approaches.

The glue seam is painted over if the component is submerged in water or is subjected to high humidity. If not, moisture will seep into him and corrosion will start to show.

To successfully adhere metal to metal, the appropriate adhesive must be selected. Choosing the right product requires a thorough understanding of the particular requirements of your project, including the kind of metals you’re working with and the conditions they’ll be exposed to. In our summary, we looked at a number of well-known brands that are trusted for their durability and strength in metal bonding.
