Epoxy Adhesives in the Construction Industry

Application of epoxy adhesive in the construction industry and its new solutions

You are probably either planning to build or you want to renovate your office, home or any place you have. Sometimes overhaul is not possible for any reason. We need tools and materials that are related to the field we want to beautify. One of these tools is epoxy adhesive. Epoxy adhesive has many applications in the construction industry, from connecting plastic pipes to adhering tiles to walls and a lot more which will be explained in this article.

What is epoxy adhesive?

Epoxy adhesive is one of the structural adhesives that is widely used for industrial and construction purposes and is very different from ordinary adhesives that we use at home. Because it’s capabilities are completely different depending on the field in which it is used. 

Features, benefits, and properties of the epoxy adhesive include the following:

  • Resistant to vibration and shock.Insulation against electric currents.
  • Resistant to different temperature degrees (-30 to 150 degrees).
  • Ability to fill seams.
  • Long service life of up to 50 years.
  • A completely solid composition and without solvent.
  • Having chemical resistance in acidic and alkaline environments.
  • Are very resistant to bad weather conditions such as storms, hail, floods, winds and storms, rain and snow, and in other words are resistant to corrosion.
  • They play a protective role against humidity and the sun’s heat.
  • They are very easy to install and use. Non-shrinkage and non-expansion after curing.

Epoxy adhesive, in addition to its properties and characteristics, has many applications that make this adhesive different from other adhesives used in the construction industry. Because products with very high resistance and efficiency play a leading role in construction.

Applications of epoxy adhesive include the following

  • Used to connect homogeneous and heterogeneous surfaces.
  • It can be easily used on all surfaces.
  • Room temperature curing.
  • Permanently connects heterogeneous surfaces.
  • Distributes stress evenly.
  • Applies repair envelope for a variety of equipment and supplies.
  • Corrosion-resistant coating.
  • Used for leaking service lines, which of course is used in industry.

How is epoxy adhesive used to bond different surfaces?

Epoxy adhesives are not the same and have a variety of materials for each capability and every surface. These adhesives can be used to bond stone, metal, wood, concrete, polymer products, fiberglass, and other heterogeneous surfaces.

Epoxy adhesive for stone installation

It is a two-part adhesive based on epoxy resin and is used for materials and equipment made of stone. In the construction industry, it is mostly used for stone facades inside and outside the building. Epoxy adhesive for stone cures very quickly. It takes a maximum of 10 to 50 minutes.

Other features include:

  • It does not shrink
  • It has the ability of engraving and sanding
  • Very small volume is
  • Can be combined with powder paints.
  • Petroleum solvents and acids cannot damage the adhesive.

Tips to consider when using epoxy stone adhesive

Before use on surfaces, your surface must be thoroughly clean and free of any dust, dirt, grease, and solvents.

Epoxy adhesive for stone facade installation

Facade stone installation in construction is done with epoxy adhesive. This adhesive can be used to install all kinds of marble slabs, granite, large ceramic tiles, etc. Megatite S adhesive is very suitable for this. 

What are the properties of Megatite S epoxy adhesive?

This adhesive is a two-part epoxy adhesive and has properties such as consistency, void-filling surfaces that are used in construction to fill joints and materials. This adhesive can be used easily after mix and is cured at room temperature and used to adhere to stones, concrete and ceramic surfaces, and any stone that is related to the appearance of the building.

You can also use this epoxy adhesive to adhere marble to an open kitchen or building facade and install ceramics.

Advantages of Megatite S epoxy adhesive:

  • mix ratio 1 to 1.
  • Semi-solid structure, flexible
  • Consistent on vertical surfaces
  • Fast application
  • Ability to cure in cold and humid conditions
  • Higher compressive and tensile strength than concrete
  • Excellent chemical resistance

To use this adhesive, the surface must be free of any dust and foreign matter

Megatite S adhesive is available in 2 kg, 10 kg, 20 kg packages. This adhesive can be removed by thinners before it is fully cured. The storage life of these adhesives is about 2 years if stored in a dry and cool place below 35 ° C.

Epoxy adhesive for installing ceramic tiles

In construction, it is necessary to install ceramic tiles. Megatite S and Megatite SF epoxy adhesives can be used to adhere to ceramic tiles. This adhesive has consistent and void-filling properties. In addition to tiles and ceramics, it is used for concrete surfaces, bolts, stones, metals, porcelain. The surface must be free of dust and dirt, and paints and grease must be cleaned with a solvent. On the concrete surface, the substrates must be perfectly strong, and loose components must be removed. On metal surfaces, old and rusty surfaces must be completely removed. Its mix ratio is exactly the same as resin and hardener. And its cooking conditions are equal to 7 days at a temperature of 25 degrees Celsius.

Epoxy adhesive for repairs and renovations

In construction or even repair of buildings, architects and builders usually use epoxy adhesive to repair fractures of all types of stones and concrete surfaces.

Megatite LTN epoxy adhesive is for sealing surfaces and repairing all kinds of cracked surfaces. The viscosity of this adhesive is low and it has the ability to penetrate large and small cracks in concrete and stones. Once the adhesives have hardened and are fully cured, the adhesive is completely resistant to water, ice, and weather conditions. Using this adhesive can make mortar, grout, and epoxy concrete much stronger than ordinary concrete.

This type of epoxy adhesive has very high adhesion and is very resistant to water and chemical moisture. It is also very resistant to sub-zero temperatures and temperature shocks.

The strength of this adhesive depends on the type of substrate and its strength. You must clean the bottom surface from any dust and dirt before adhering. Alcohol, diesel, and thinner should not be used for this purpose.

If the surface is well sanded and cleaned and abraded well by chemicals, the epoxy adhesive will adhere to the surface as best as possible. The resin and hardener must be thoroughly mixed at room temperature.

You must use gloves to work with the adhesive and be careful that the epoxy adhesive does not enter water or food. Adhesives are available in 20 kg, 200 kg, and 1-ton packages.

Epoxy adhesive for sealing and sealing

LTC, LTL, LTM, LTB epoxy adhesive can be used for sealing surfaces. This adhesive is used to repair cracked surfaces such as concrete and natural stones and sealing.

Megatite LTM epoxy adhesive is two-component and has excellent adhesion and thinness, and has a high ability to penetrate to the substrate, grooves, and pores on the surface. This adhesive is used to repair cracked concrete, seal concrete, stones and minerals, and porous surfaces. It is the best adhesive for sealing.

Its mix ratio is 2 to 1, it has very high strength and resistance. It is also very resistant to temperature shocks and sub-zero temperatures. 

How to work with Megatite LTM adhesive

First, you need to clean the surface from dust. To seal surfaces, mix the resin and hardener and pour on the surface to completely fill all the gaps in the surface. To repair cracks in concrete surfaces, you must heat this surface to 80 degrees Celsius. Then pour resin and hardener on it to penetrate deep into the cracks and create a permanent connection between the two surfaces.

You can also use the injection method with a low-pressure pump. First, fill the outer surface of the created cracks with Megatite S glue and then place injection nozzles in different places of the crack, at a distance of 20 to 40 cm from each other. After the Megatite S adhesive has cured, you must now seal the outer surface of the crack and pour the mixture of resin and hardener into the crack with a low-pressure pumping system. The ratio of resin to hardener mix is ​​2 to 1 by volume and 100g to 50g by weight. All the hardeners should be mixed with all the hardeners. And only if the amount of mixing is less than what we want, the two-part should be mixed for at least 2 minutes. The mixture should be used immediately. Due to the heat and high reactivity of the hardener, high volumes harden quickly. We used Megatite S glue here for better sealing.

Megatite is a manufacturer of two-part epoxy adhesives for various applications in construction, petrochemical, oil, gas, power, water, and wastewater industries.

Epoxy adhesive for planting bolts and bars in concrete

Megatite LTM adhesive can be used for bonding old to newly formed concrete, and for planting bolts in concrete. 

How to plant bars and bolts in concrete

First, drill a hole one and a half times the diameter of the bar in the bolt or concrete. All dust must be removed by the air pump. And the inside should be cleaned with a wire brush. Then insert the bolt or bar into the hole and pour the resin and hardener mixture into the hole from all around. And let the resin cure for 24 hours. 

Repair cracks and seal surfaces with epoxy adhesive

If you see cracks in stone stairs or other concrete and stone surfaces, you can easily remove them with a suitable epoxy.

Megatite LTN, Megatite LTB, Megatite LTC, Megatite LTL, and Megatite LTM are among the Megatite epoxies that are suitable for repairing and regenerating concrete cracks and natural stones. These adhesives are thin and have low viscosity. For this reason, they easily penetrate into cracks, grooves, and pores and strengthen them. By adding compatible silica with epoxy resin, you can make grout, mortar, and epoxy concrete with much higher strength than ordinary concrete.

Conclusion

Epoxy adhesives have a wide range of applications and are used to reconstruct and repair materials. These adhesives can also penetrate concrete parts and increase their strength. If you are planning to build a house or any place and you want to have major repairs, you can definitely use Megatite epoxy adhesives in different applications of different surfaces.
