Two-component adhesive: types and application

For bonding various construction and finishing materials in most cases a special adhesive is used, which includes two components. Such glue provides durable and reliable adhesion of various materials. But before using this substance in the process of repair work, it is necessary to familiarize yourself with its characteristics, features and scope of application, and in order not to be deceived by dishonest manufacturers, it is also important to analyze the manufacturers of two-component compositions in advance.

Two-component adhesive combines two types of ingredients - special resins, as well as hardening agents. The latter may have a different state of aggregation: liquid or powder.But in any case, it is necessary to carry out the main procedure before using the glue - mixing its components, which provides the material with the ability to harden.

To prepare the composition properly, it is necessary to strictly follow the instructions for its breeding.indicated on the package. The manual contains information on the proportions of the ratio of components and on the time required for aging after dilution. Some formulations imply a different way of mixing the two substances. If two surfaces are to be glued together, then resin is applied to one, and a hardener is applied to the other, and the mixtures are mixed immediately when two surfaces are joined.

The two-component composition quickly sets to the surface and hardens. In addition, it is very difficult to remove. In some cases, the process of gluing or embedding with the help of epoxy resin becomes irreversible, so it is important to carefully prepare the surface so that the adhesive composition in addition to performing its key functions does not contribute to the appearance of incidents in repair.

Two-component material for gluing wood and other surfaces is often sold in buckets. One of the components is presented in a dry form.In this case, add the dry component to the bucket and mix both components thoroughly.

Depending on the specific brand and specific components in the composition of the epoxy such glue can be stored for half an hour to two hours. Then it becomes unusable due to the thickening of its consistency.

When the composition is already applied to the surface, it will maintain its performance over 1-2 hours.

Compared to other types of adhesives, two-component adhesives have a number of special positive characteristics.

These include some positions.

• High drying speed. Such a solution does not contain various solvents or water components, so it can dry after one day after application.
• High strength. Epoxy solution glues materials for a long time. In addition, it can be applied absolutely on any basis.
• Water resistant. After processing with such glue, the material will not react worse to contact with water. Glue has the ability to not pass the liquid and not absorb it.In addition, the characteristics of the solution will not be affected by contact with moisture.

• Glue solution does not transmit electricity.
• Adhesion level is very high.
• The composition has an elastic structure.
• Glue does not have a negative impact on materials from the array.
• After drying, the adhesive joint is not subjected to deformation.
• The material is not prone to shrinkage after a certain time after application.

• Even despite the presence of harmful substances, glue is not dangerous, because these substances as the composition solidifies simply disappear.
• The composition is not exposed to the harmful effects of various bacteria and mold.

The disadvantage is the relatively high price, but among the variety of products you can always find an option that corresponds to the financial possibilities.

Although the two-component glue is a versatile material, it still has a number of varieties, each of which has its own characteristics.

The main types of composition are several types.

• Polyurethane adhesive with epoxy component. He often becomes an alternative to mounting with screws. This solution has a 20% elasticity and is sold at an affordable price.
• Even more elastic composition, designed specifically for attachment to the base of the parquet, is a polyurethane adhesive without epoxy resin. Its elasticity index can reach 40%, but such a substance is sold at a higher price.

• Acrylic 2-component adhesive is presented in the form of such varieties as a modified composition. It includes an activator that is applied to the surface of the product. Only then can gluing be carried out.
• Among the acrylic varieties, there is also a two-component dispersion adhesive, based on water. This compound is durable due to its high level of adhesion to the surface and safe from an environmental point of view.

• Adhesive for PVC - composition, the performance of which can last up to 8 hours. It also provides for the possibility of additional addition of hardeners. For industrial work with PVC material, a kind of two-component composition is used, such as 3M, which includes special equipment for application.
• Special is non-shrink two-component solution, which has a transparent color. This epoxy compound is multifunctional, as it is capable of fastening as complex electronics parts, there are small decorative elements.

Due to the excellent adhesiveness of the substance of a two-component composition You can glue different types of structures.

• A two-component polyurethane composition for gluing parquet is very popular. Parquet glue adheres to the boards better if tapped after gluing, thereby eliminating unwanted voids.
• If it is necessary to attach plywood with dowels, an alternative fastening that is not inferior in strength, can become a two-component adhesive.

• The composition of this type is perfect for laying ceramic tiles or mosaics. Due to its special properties, the material ensures reliable adhesion of the tile covering to the base on both horizontal and vertical surfaces.
• With additional heat treatment using an adhesive composition can be joined parts made of metal, aluminum or other heavy materials.
• Using two-component glue, even massive products made of natural and artificial stone, such as marble and granite, are connected to each other. It can be various panels used for interior decoration.

• Products made of glass can often be broken due to their fragility. But epoxy glue will be an excellent link to restore the shape of dishes, vases and other glass items.
• Two-component material is used to repair shoes, some items of clothing and accessories.

Such a wide use of the adhesive composition allows it to be used in everyday life as a universal method of bonding various materials. It is enough to have one tube of such glue in the house in order to easily eliminate a lot of breakdowns.

Sometimes epoxy glue is used to make concrete parts. For this, the composition is poured into special forms.

During the finishing works, the adhesive composition is used to seal the gaps in the floor covering screed, which allows to correct small defects formed during construction.

In the market of building and finishing materials there is a variety of such compositions. Select the most popular manufacturers.

• "Uzin MK 92 S" - is a unique adhesive, which is characterized by a very long service life. This quality is due to the increased strength of the material.
• Two-component adhesive mixture Poxipol is a unique material because it can harden, even while under water. Such a component as contact adhesive does not include toluene. Within half an hour the mixture can already dry.

• To glue heavy materials, such as metal, steel, titanium or cement, is used "Universal two-component composition 302". It is sold in tubes of 10 g. It is important to remember that such a substance cannot glue zinc, polyolefins, copper and celluloid.
• Trademark adhesive Interbond It is used as a binder between materials made of wood, plastic, MDF, plywood and other non-heavy materials. Its peculiarity lies in the fact that one of the substances is presented in the form of an aerosol, which must be sprayed onto one of the surfaces to be joined.

For many users, the complexity of the choice of glue.

To choose the right composition should take into account a number of factors, which include some nuances.

• Type of work. It can be finishing works, wall cladding, parquet flooring. Glue is also used to repair and join parts. The volume of the required material directly depends on this factor. Sometimes it is enough to purchase only a 10g tube.
• The material that you need to stick. It defines the specific type of two-component adhesive. Not all varieties have the ability to connect parts from any raw material, so you should purchase special formulations.

• Financial expenses.It is necessary to calculate the admissible value of the adhesive based on its capabilities. For some works, it is not at all necessary to buy the most expensive adhesives, because a cheaper analog can also successfully cope with decoration and repair.
• When a user decides on a particular brand of glue, then you need to remember to read the reviews about its manufacturer - this will help to verify the characteristics of the material, learn some secrets of use and in some cases protect yourself from the purchase of low-quality products.

To use a two-component adhesive in various fields was easy and effective, it is necessary to listen to the recommendations of construction and repair professionals and experienced users.

To facilitate the process of working with glue to help tips professionals.

• The polymerization process is not fixed clearly in time. It can be influenced in various ways. If it is necessary to speed up the procedure, it is recommended to increase the ambient temperature. Some craftsmen prefer to add a hardener in large proportions to speed up the process.If you need to extend the process, you should add less hardener than indicated in the instructions.
• If parquet is laid on a two-component connector, then it is recommended to wait for complete drying not 24, but 48 hours.

• Do not forget about the means of protection when working with epoxy two-component adhesive. These include gloves, dressing for respiratory protection. It is necessary at the stage of mixing the components, since at this stage the emission of harmful substances may occur. Gloves come in handy so that the glue does not get on the skin of the hands, because it is quite difficult to wash off.
• If in the process of repairing a two-component adhesive got on the skin, then acetone solution will help to wash its traces.
• Draft indoors should be avoided while working with this adhesive.
