Two-component polyurethane adhesive: features of choice

In the process of carrying out repairs, you cannot do without special bonding compounds. For this, professionals and ordinary buyers use adhesives of various compositions. Two-component polyurethane adhesive is widely used. This is a versatile way to reliably connect finishing materials and other details. Due to its high performance, the product has earned respect in the world market and among Russian buyers.

The name of the composition speaks for itself: there are two components at the base of the glue, each of which performs its own individual function.

• Element number 1. Complex polymers combined with polyhydric alcohols. Outwardly, it is very similar to a viscous and viscous paste. Thanks to him, the glue has high elasticity, practicality, viscosity and transparency.
• Element # 2. The second component, which creates the required consistency, is called diisocyanate. The above two elements are connected in the same proportion.

Experts highlight a number of features of 2-component adhesives.

• The compound can be used to bond a variety of materials. Both artificial and natural. Using it, you can work with wood, fabric, metal, plastic, rubber, stone. Thus, one product is enough for a huge front of work.

• The glue is not afraid of temperature fluctuations. A quality product will retain high technical characteristics, both at high and low readings on the thermometer.

• Does not deteriorate under the influence of excessive moisture, fuel or oil. Mold, fungus and other negative processes are also not scary.

• The shortest bonding and drying times will make the workflow faster and more convenient. This is the best choice if you need to complete the work as soon as possible.
• The finishing material will securely hold the necessary elements on horizontal and vertical surfaces. The polyurethane compound has excellent mechanical properties.

• When working with MDV or PVC structures, the glue acts as a high-quality, durable and wear-resistant sealant. The hardened layer will help reduce noise levels and keep the room warm. If the region has a harsh climate, such glue will definitely come in handy.
• The product is economical to operate. A profitable expense will help to save a significant part of your money, especially when it comes to repairs on the basis of large objects.

Experts and users highlight only one drawback of glue based on two components - this is a long drying time. However, this indicator is fully offset by the final reliability, durability and other advantages. On the other hand, the disadvantage can be regarded as an advantage from the point of view that the master has enough time to adjust the repair until it completely solidifies.

Before purchasing glue and getting started, you need to familiarize yourself with the individual characteristics of this type of compound. Knowledge of the main characteristics will help determine whether the material will cope with the task at hand.

Technical features of two-component polyurethane adhesive further.

• Product consumption per one square meter of surface is from 800 to 2000 grams. The indicator varies depending on the type of work and type of foundation.
• The work must be carried out under certain temperature conditions. The lowest indicator is - 20 C.And the maximum is 80 degrees with a plus sign.

• In the process of applying the glue, make sure that the temperature in the room remains within the range from + 15 to + 30 C.
• Store the product in a tightly closed container, away from sunlight. Temperature storage conditions: from zero to 50 degrees Celsius.

• The maximum shear strength is 3 Newtons per square meter. mm. Be sure to consider the limit when repairing and adjusting.
• It takes 24 to 48 hours for the glue to fully cure. It all depends on the layer. The thicker it is, the longer it takes to solidify.

• For one liter of liquid 1.55 kg.
• The composition of the glue is completely free of organic solvents.

• The adhesive can be used in conjunction with underfloor heating technology.
• The product differs from similar compositions in high adhesion to alkalis.

• Considering the above technical characteristics and a number of advantages, it is not difficult to understand that the glue has a wide range of applications. Over a long service life, the adhesive retains its strength and reliability. The parquet adhesive is highly resistant to constant stress, even several decades after the installation of the floor covering.

• The glue has an amazing property of expanding at the slightest deformation. It provides additional hold between the individual planks. In this way, you can be sure that the parquet will not decay. Due to the dense structure of the substance, moisture will not collect between the elements, which has a destructive effect on wood and metal elements. Remember that dampness causes bacteria to multiply.

• The glue will perfectly cope with the functions assigned to it when working with tiles. The composition will provide reliable adhesion of the tile to a horizontal or vertical surface. The product can be used in bathrooms where high humidity is maintained. Water, steam and dampness do not appear for durability and practicality.

• Various decorative elements made of stone, glass, marble and other materials are attached using polyurethane glue based on two components. By using a quality product and following the instructions for use, the parts will be reliably attached for years to come.

• Repair professionals say that working with a polyurethane compound is not as difficult as it might seem at first glance. Even a beginner can use it, but only if he strictly adheres to the instructions. For application it is necessary to use a special spatula. It is recommended to purchase it immediately when purchasing the glue.

Before applying, you should first prepare the surface, otherwise it will not work to achieve the expected result. The base must be cleaned by removing debris, dust and other contaminants. You also need to remove roughness and burrs. The glue can only be applied to a completely dry surface.

Stir the glue thoroughly to form a homogeneous mass. This procedure is necessary so that the layer lays down neatly and evenly. It is recommended to use a spatula for mixing.

Now is the time to apply the product directly. You need to use a special tool. The maximum admissible layer of glue should be 1 cm. Make sure that the glue covers the surface evenly and that there is no distortion, shifts or other imperfections.

When a sufficient amount of glue has been applied to the surface, it is necessary to fix the necessary elements to the base. It is recommended to carry out this procedure for one hour so that the weather does not spoil the adhesive layer. Otherwise, the composition may lose almost all the properties guaranteed by the manufacturers. Before repairing, it is imperative to calculate the time that you plan to spend on each of the actions.

If you apply too much glue, you can easily remove it. Use a soft cloth dampened with pure alcohol. It is recommended to carry out this procedure immediately so that the glue does not have time to harden.

The contact area of ​​the product with the composition should be at least 75% of the total surface dimensions. As soon as the work is finished, it is necessary to leave the room for a day or two. At this time, refrain from any work and manipulation in the treated area. After the expiration of the above period, the components will reliably interconnect.

When using the glue, it is necessary to follow exactly the instructions that the manufacturer places on the purchase. Also, do not forget to protect yourself from injuries and other damage.

It is necessary to apply the composition with thick rubber gloves of sufficient length. It is advisable to cover your eyes with protective goggles while stirring the glue.

If glue gets on the skin, remove it immediately. The best way to use warm water and soap. If particles of glue come into contact with the eye shell, you should immediately consult a doctor. Ensure adequate air circulation during application. If this is not possible, cover your face with a respirator.

It is recommended to use the unpacked adhesive within six months. After opening the sealed package, moisture begins to penetrate into it, a large amount of which will spoil the technical and operational characteristics of the glue.

If you are choosing a product for local renovation or finishing a small room, it is recommended to purchase a small package of the composition. Knowing the consumption, it is not difficult to calculate the required amount of glue.

It is not difficult to extend the shelf life of polyurethane two-component adhesive by listening to simple rules. Remove excess air from the package before closing the tube after the repair is complete. Just push gently against the sides of the package. Make sure the cap fits snugly against the package.

Store packaging upside down. This method will prevent the pieces of glue from sinking to the bottom and blocking the spout of the package. Renovation technicians recommend building a vertical supply for the polyurethane adhesive. For this design, only two boards are needed. Using a drill, you can quickly make holes for the size of the adhesive caps. This storage method will increase the product's lifespan as much as possible.

A polyurethane-based substance has been used in the repair industry for a long time. It has all the properties you need to get an excellent result. Moreover, the substance is used to repair vehicles such as boats or cars.

This is a practical and reliable tool that provides a tight and long-term docking of elements, regardless of the material. Despite its professional characteristics, the glue can be easily used at home, even without some experience.

The modern market offers a huge range of products. The product is offered by domestic and foreign manufacturers. Products of the Uzin brand are highly valued.
