Polymer adhesive: features and specifications
Nowadays, adhesives based on polymeric materials are popular. There is a lot of such compositions, which allows the buyer to make a suitable choice. Often preferred universal polymeric materials. Among these compounds are popular glue PVA, "Dragon" and "Moment".
What it is?
Mostly polymeric compounds are used during construction and repair work. Such a composition appears to be a plastic mass, which consists of a polymeric material and an additional substance that provides high-quality fixing of the adhesive to the surface. It is believed that the main advantage of this glue is a high level of adhesion to the treated surface.As for the shortcomings, there are quite a few of them, but one can single out the toxicity of this material. Due to this lack of all work with glue must be carried out in the means of protection.
If glue is chosen for wall cladding tiles or stone, it is often preferred products with a polymer-mineral composition. They are made of cement-sand mixture with the addition of various polymers.
Thus, it can be understood that the higher the requests for finishing, the more complex the formulation of the polymeric material that is included in the glue should be. For example, a certain type of polymeric material is able to increase the water resistance of the adhesive composition, and if there is no polymer in the composition, water will begin to penetrate the joints, and thus will begin to destroy the cement mixture, as a result of which the cement will begin to crumble.
There are polymeric additives that increase the level of adhesion of the mixture to the treated surface or increase the elasticity of the adhesive. Due to these characteristics, the adhesive can act as a shock absorber between the tile and the wall, and this is a very important point, since in the event of a possible load on the tile or deformation, the adhesive will be able to extinguish such factors.
According to experts, the polymer components of the dry or liquid form significantly improve the quality of the adhesive, it becomes resistant to water, elastic, strong and durable. Compounds of this type are applied in a small layer, which depends entirely on the thickness of the finishing material.
Glue can be presented in several versions:
- latex, which is a liquid polymer;
- a powder based on a polymer that must be mixed with a special solvent before use;
- granulated, for its use it is necessary to warm up well;
- transparent universal liquid material based on polymer is the most popular and relevant, since it is convenient to work with it, and it is already ready for use;
- the polymer-based film may have a closed and open type adhesive side.
As mentioned above, the main features of the adhesive based on polymers are considered to be a high adhesion index and a high hardening rate on the treated surface.
Also among the features include:
- comfort of applying the composition to the surface;
- drying speed, but it depends on the layer thickness;
- the elasticity of the composition, due to which during the work you can adjust the location of finishing materials;
- transparency of the composition after solidification;
- possibility of use for filling gaps in 0.5 cm;
- the composition does not contain solvents.
It is possible to use polymer glue both for small construction works, and for extensive repair. Such a factor is justified by the fact that these materials have quite a lot of varieties, due to which the mixture can be selected for use for any purpose.
Polymer-based material is popular among car owners, because some types of such glue are used to repair glass. After applying the composition to the glass and its complete drying, it becomes transparent, it is almost invisible, but cracks on the frontal or other glass will be masked in this way.
For internal repairs, dry mixtures based on polymeric materials are mainly used, but they must first be mixed with water. Dry mixes are more popular because they are not as toxic.
They are often used for such works:
- parquet fastening;
- tile laying;
- fixing sheets of drywall;
- minor repairs of household appliances and furniture;
- fixing ceiling tiles;
- fixing decoration elements.
Use such compositions for external construction works, which are associated with the finishing of the facade of the building. They can even secure the overall elements. For example, “Moment” construction adhesive based on a polymeric material is excellent for attaching plastic, plasterboard, stone and tile. And for roofing, a special blend based on a bituminous polymer is made.
This composition is similar to black paste and copes with all the aggressive environmental influences. The characteristics of the glue allow you to use it for tile, clay, glass, even for balloons. The most important thing is to dry the mixture correctly or dilute it according to the instructions.
How to choose?
When buying an adhesive based on polymer, it is recommended to pay attention not only to the adhesion property, but also to the elasticity, incombustibility of the composition, electrical conductivity and thermal conductivity of the material. In order for the glue not to burn, antimony and similar components are added to the composition during manufacture, and in order for it to conduct heat, boron nitride must be included in the composition.Polymer-based glue is constantly being improved, thereby attracting the attention of more and more new consumers.
How to calculate the flow?
It is best to calculate the consumption of glue based on polymer material through the official website of the manufacturer of this brand. Manufacturers' websites almost always have the option of calculating the flow rate in the form of a calculator, where you need to enter information about the material that is used, the floor space and the specific type of glue. After that, an automatic calculation is performed. It is considered the most accurate: there is no need to spend money on the stock mix.
How to use?
In order to start work with the use of glue based on polymers, it is necessary to pre-prepare the surface. To do this, it must be well cleaned and degreased. If you do not carry out such manipulation, the flow of the mixture will increase significantly. Also may suffer and reliability of fastening material. In the event that the surface is regularly exposed to moisture, it must be primed.
After the surface is prepared and dried, you can start applying the material to the substrate, but you need to monitor the uniformity of the layer: it should not be very thick.Then the glue is applied to the glue, they are pressed tightly and held for a certain time (according to the instructions on the package).
If the composition is toxic, the room must be well ventilated. Rubber gloves are recommended for hand protection, and a respirator should be worn to protect the respiratory tract.
Manufacturers and reviews
From the popularity of the manufacturer depends not only the cost of the composition, but also the quality of the product, as well as the reliability of fixation of the material to the surface. If you are counting on the average cost of glue, then experienced builders and amateur decorators recommend paying attention to the products of domestic manufacturers. These include: polymer glue "Moment", "Litokol", "Master", "Artelit" and "Front". However, the vast majority of reviews are devoted to more famous brands. These include Ceresite, Polimin, Knauf, Thomsit and Anserglob.
The quality of the work done depends not only on the choice of the product from a popular brand, but also on compliance with the technology. If you adhere to the installation technology, then any adhesive based on the polymer component is suitable for the performance of work.
