What is resin, epoxy, injection?

Injectable epoxy resin is a two-component, solvent-free substance consisting of two components: hardener and agent.

Epoxy injection resin is a thin yellow liquid that has high resistance to chemicals and impact.

This epoxy resin can easily penetrate into cracks and perform the task of repairing concrete cracks with high adhesion and hardening power.

It does not shrink when it dries, it can be used on dry and wet concrete surfaces to repair concrete cracks and strengthen structural elements.

Epoxy coating with a thickness of 4 mm increases the compressive strength of concrete by about 21100 kg/cm.

Epoxy resin with its low concentration and high penetrating power has high initial and final strength.

 

In what cases is injectable epoxy resin used?

– as a coating on the floor of halls, factories and other surfaces to increase the resistance of concrete against corrosion factors and chemicals

Filling seams and repairing concrete cracks

– Reinforcement and strengthening of structural elements such as beams, columns, floors, etc.

– It has adhesive strength and high penetration ability and repairs cracks in concrete

– Making FRP composites for use in various industries such as building renovation and retrofitting

– Making FRP composites

– automobile manufacturing

– Aircraft manufacturing and…

 

Concrete , crack repair work steps:

After cleaning the contamination from the surface of the packer element or nipple, which has the task of transferring the resin into the crack, we place it at specific intervals, then the injection operation until the resin Epoxy We continue with non-recoil injection and finally cores are taken from the concrete cracks to ensure the correctness of the reinforcement. Injected epoxy resin is widely used in strengthening structural members and repairing concrete cracks.

The most practical , resin, epoxy:

The most useful epoxy resin is in strengthening the building with FRP, and it consists of two parts, epoxy resin and hardener, and it has very high resistance.

Some features The glue , epoxy that has made this product so popular is:

• The tensile, bending and compressive strength of epoxy glue is very high. Therefore, they play a major and important role in the construction of FRP composites and the building retrofitting industry.
• Epoxy resin is highly resistant to various chemical substances such as acids, salts, oils, solvents, etc. and is not affected by these substances.
• The price of epoxy glue is very affordable and economical due to its high adhesion and wide application
• Epoxy resins are very stable against heat, wear and moisture.
• Epoxy glue does not shrink when it hardens and provides very high adhesion with all surfaces.

 

What is primer , epoxy?

Epoxy primer is a two-component material based on epoxy resins, which has the ability to penetrate deep into concrete and is used to prepare concrete surfaces in strengthening and reinforcing structures with FRP composites. The adhesiveness of this epoxy resin is high and it has great penetrating power, hence it is widely used in strengthening the structure.

The reason for using epoxy primer in industrial tanks and metal structures:

Due to its good adhesion with metal surfaces, this product can be used in industrial tanks and metal structures.

 

Epoxy primer can be used as a primer for repair mortar and epoxy industrial flooring on concrete surfaces, sports hall floors, laboratories, etc.

This product withstands the stresses from the floor when used as the bottom surface of the floor.

 

What is epoxy putty?

Epoxy putty, a solvent-free two-component material based on epoxy resin, has high adhesion and has high mechanical, chemical and thermal resistance.

Uses of epoxy putty:

– In order to level the surface of the bed and fill the seams and gaps of retrofitting projects,

– Strengthening the structure with FRP composites

– Filling voids and cracks and leveling and repairing damaged concrete

– Can be used in bathroom services, flooring in factories, swimming pools

– Can be used as the middle layer of epoxy floors

– Can be used on vertical and horizontal surfaces

– It does not shrink when it is applied

– Easily penetrates cracks

– After it is attached, it works as an integrated system.

– High resistance, insensitivity to humidity and environmental factors, ease of implementation and high adhesiveness of epoxy putty are the advantages of this epoxy resin, which has made it used in retrofitting buildings.

 

 

Why is another name for epoxy resin, epoxy restorer?

Because it is used in the repair of concrete surfaces to install FRP fibers in retrofitting projects.

 

What is the reason for the mixture , epoxy and hardener not drying?

When working with epoxy resin, we may face the following problems:

• Epoxy resin not drying:
• Viscosity and softening of epoxy resin

The things that we must follow to avoid these problems are:

• Compliance with the correct mixing ratio:

Resin not drying can be due to the lack of hardener in the system.

• The presence of water or moisture in the system:

The epoxy resin mixing container is not completely dry, or the working surface or the air is humid

• Epoxy and hardener are not well mixed
• Temperature control

The air temperature should not be less than 10 degrees and the surface temperature should not be less than 5 degrees Celsius because the reaction of epoxy and hardener stops at low temperature and the resin will not dry; too hot air can interfere with the drying of epoxy resin, the maximum temperature The air for application can be 50 degrees Celsius.

• Surface contamination

Contamination of the work surface, such as the presence of grease and dust, interferes with the drying of the epoxy resin.

 

 

What are the disadvantages of epoxy resin?

• Its price is more expensive than other types of resin.
• Epoxy resin processing is time-consuming because the curing time of epoxy resin and the polymerization process are long.
• Epoxy resin is not malleable and is sensitive to cracking.
• It does not work at temperatures below 5 degrees Celsius.

 

What are the properties of epoxy resin?

• Chemical resistance
• High resistance to water and humidity
• Resistant to absorption of mechanical and thermal stresses
• مقاومت بالا در برابر سایش و ضربهHigh resistance to water and humidity
• Very good adhesion to materials and compatibility with all types of fibers and FRP system
• High filling capacity
• Light weight and small volume
• Useful life and high repair speed
