Surface Preparation

Resin and hardener must be kept in 77°F (25°C) for 24 hours before application. All surfaces must be clear of any grease, dust, hardeners, and other contaminants and should also be clean and dry before applying epoxy adhesives. The surface of any product to be adhered must be prepared to access the pure hard surface underneath which is to be covered with the adhesive completely. The surface must first be sanded with an abrasive roller with a diamond blade, the resulting dust should be removed with a fiber brush. After that, the remaining dust can be removed from the surface with a damp sponge to ensure complete contact. Finally, dry the surface completely with a piece of cloth, then start using the adhesive.

Mixing Megatite S Epoxy Adhesive

Use the spatula to mix thoroughly by 1:1 ratio (1 parts resin, 1 part hardener). Mix for minimum 2 minutes until a homogeneous mix is obtained.

Processing

The strength and durability of a bonded joint are dependent on proper treatment of the surfaces to be bonded. At the very least, joint surfaces should be cleaned with a good degreasing agent such as acetone, to remove all traces of oil, grease and dirt.

In concrete surfaces must be completely solid with no loose pieces. Iron surfaces must be cleaned of rust.

Tile size Adhesive spot diameter
300*300 mm
50 mm
600*600 mm 100 mm
900*900 mm 150 mm

 

In addition, the amount of Megatite S adhesive used depends on the weight of the stone or tile to be attached to the wall. The following table is set to cover 10% of the surface of each tile with adhesive:

The amount of inclination of the wall Thickness of adhesive layer Coverage with 10kg of adhesive
Completely vertical wall 3mm thickness 16-17 m2
6mm inclined wall 6mm thickness 8-9 m2
12mm inclined wall 12mm thickness 4-4.4 m2

After the tile was set in place, necessary settings for regulation and leveling of the adhesive can be performed.
For larger stones and tiles, place spots with approximately 60g in 30cm distances from one another (horizontally and vertically) as shown in the following pattern.

Directions for Use

  1. Before mixing ingredients, degrease, clean and dry both surfaces completely. You can use acetone, ethanol, methanol or other solvents. Use a cloth or soft sandpaper to clean surface of any dust or foreign matter. If the adhesive was not added within one hour after cleaning, the cleaning process must be repeated.
  2. Mix all the resin in the container with all the hardener, never mix an approximate amount of the ingredients. The formulation must be thoroughly mixed for at least three minutes until a homogenous mixture is achieved.
  3. Apply adhesive with a 0.5-0.8mm thickness on the inner surface and a 0.8-1mm thickness on the outer surface of the bond then slowly bring both surfaces close to each other to tighten. Rotate the tube by a quarter period if possible. Make sure the bond is set completely. If needed, use a wooden hammer to hit the end of the pipe. Never hit pipes and fittings with a metal hammer.
  4. Remove excess adhesive with the spatula.
  5. Ensure the heat curing cycle before using or testing the pipe line. You can find full cure time in different temperatures in table 2. No impact stress should be applied on the connection during cure time (i.e. removing or shaking pipes). To achieve maximum chemical and mechanical properties, expose the bond to cure in 302°F (150°C) for one hour using a heating blanket.

Processing

The mix ratio is five parts of resin to one part of hardener (100g of resin to 20g of hardener.)

Mix ratio According to weight
Resin 100g
Hardener 20g

 

Megatite PH mixture

The formulation can be applied directly or using a spatula on the clean and dry surface. The joint components should be assembled and clamped as soon as the adhesive has been applied.  An even contact pressure throughout the joint area will ensure optimum cure.

member of the vendor list

Pouyesh Composite Yekta, a member of the vendor list or long list of in-house manufacturers at the Ministry of Oil

The Ministry of Petroleum updated its long list of resources on May 12, 2020, listing 1,287 companies as sources of supply for the ministry’s central office, which also includes the name of the Pouyesh Composite Yekta company in this list.The explanation of this update stated that: “The resources available in the country have been evaluated by the technical and commercial committees of the central system, and the names of these have been identified according to the report of the head of the central apparatus at the Ministry of Oil. Sources that obtained the approved quorum. In 2018, a long list of sources was evaluated. Centrally located, the circular of 2016, issued by the Minister of Petroleum, No. 2-20 / 437057, obliges all major companies and companies affiliated with the Ministry of Petroleum to use the Ministry’s resource list at all levels of transactions.

What is a vendor list?

Professional clients, such as government agencies, prepare a long list to access the specific goods or services they need to be provided with in a short time, by evaluating suppliers and manufacturers with reputable reputation. This list is called an Approved Vendor List.Supplier is a reputable commercial company that supplies goods or services that have been approved by that organization.

How does a vendor list work?

In large industries such as petrochemical, oil and gas, steel, power, etc., the sensitivity of project implementation is very high. The slightest error or use of substandard goods can lead to project failure and loss of resources. To ensure that contractors, establishments, or organizations purchase and also monitor them, they first rate the manufacturing and distribution companies with various assessments and test their products.

The companies that have the minimum quality assessment indicators that have been approved by the Supreme Council for the Review of Institutional Resources are then grouped into a long list or vendor list. At the time of implementation of the project, the business owner attaches a list of all goods, equipment and approved manufacturing or distribution companies, that is, a list of vendors. The contractor is also required to purchase and use all equipment and items required for the project from suppliers within the vendor list.

How do I check the list of oil companies’ sellers?

To search for resource status in the long list of the Ministry of Oil, all you have to do is enter the official electronic supply system for the oil industry and enter the “national identity” or “Iran code” of the company in the search box. If the company in question is a member of the Ministry of Petroleum’s vendor list, it will be shown in the search results.

What Are Epoxy Resins

What Are Epoxy Resins

All you need to know about epoxy resin adhesives

There are tons of articles on the Internet about epoxy resins, and most of them address the topic superficially rather than expertly. It is clear to everyone that epoxy resin has many applications in various industries from construction to the petrochemical, oil, power and water industries. You may also have many questions and are looking for a scientific answer to them, such as what exactly is epoxy resin? What is its chemical composition and molecular components? Or what are the properties and advantages of epoxy resin? This lack of scientific content convinced us to study epoxy resin in this article. This article is dedicated to introducing you to epoxy resin, so keep on reading.

Epoxy resin and its chemical composition

Epoxy resin was discovered in 1938 by Pierre Castan, which has many applications in various fields, such as paint, electricity, civil engineering, etc. Epoxy resin is widely used because it has a very high ability to bond with other surfaces. Additionally, it attains high mechanical strength and chemical resistance after hardening.The distinguishing feature of these resins is that they contain more than one group of 2 epoxy resin in their molecular structure. This group may be in the body of the chain or at the end.

 

The chemical composition of epoxy resin consists of two parts, epoxy and non-epoxy. The non-epoxy fraction may be aliphatic hydrocarbons, aliphatic silico or highly cyclic hydrocarbons. In practice, the product of the BPA and epichlorohydrin reaction often forms common epoxy resins. These products hold 80 to 90% of the market share.Previously,
epoxy resin was used almost exclusively as a surface coating. Before World War II, high production costs of bisphenol A and epichlorohydrine prevented epoxy resins from being marketed. Subsequent efforts and the invention of new production methods gave rise to the economic acceptance of these resins.

Properties of cured epoxy resins

Epoxy has many active functional groups and can form a network structure in the presence of curing agents and stiffeners. The properties of the hardened epoxy depend on the following factors:

  • The type of epoxy resin
  • The type and amount of hardener
  •  Crosslinking rate
  • The nature and volume of additive additives

There are many hardening agents on the market that have longevity, elasticity, fast hardening properties, and low toxicity.

The molecular structure and properties of the cured resin depend on the nature of the curing system. Although there are different curing systems, they can be divided into two groups: amines and anhydrides.

Epoxy resin and hardening agents are not the only components of the formula. For some applications, unmodified epoxy may have undesirable properties such as high viscosity, high cost, and low impact resistance in some special applications. Therefore, in most cases, it must be accompanied by substances such as thinners, fillers and reinforcers. Correct selection of resins, hardeners and additives allows to achieve the desired properties, and this diversity is a major factor in the long-term growth of the epoxy base.

Properties of epoxy resin

In addition to this versatile structure, epoxies also have the following properties:

  • Excellent chemical resistance, especially in alkaline environments
  • Good adhesion to a group of different substrates
  • Very high tensile, compressive and bending strength
  • Low shrinkage after hardening
  •  Dimensionally stable
  • Excellent electrical insulation
  • High durability in harsh environmental conditions
  • The possibility of curing at different temperatures
  • Excellent resistance to stress
  • Odorless and tasteless

Types of epoxy based on the method of hardening

Epoxy adhesives are generally divided into two groups of one-component and two-component epoxy adhesives according to the processing method.

one-component epoxy adhesives

The one component adhesives are cured after application at a temperature between 250 and 300°F and do not require a hardener. This set has excellent adhesion and shows very good resistance in adverse weather conditions.

Two-part epoxy adhesives

In addition to being able to harden at high temperatures, two-part epoxy systems can be processed at room temperature to zero degrees with the help of catalysts and stiffeners. For this reason, this group of adhesives is widely used in industry. After adding the hardener to the epoxy, the chemical meshing process begins generating heat until it is completely hardened. This range of adhesives is highly adaptable to environmental conditions and can be formulated for any application.

Manufacture of epoxy adhesives

Two-part epoxy systems consist of a resin fraction and a hardening fraction that exhibit different thermal, optical, electrical and mechanical properties in different formulations. These systems can also be formulated to be hardened at room temperature and at high temperatures.In Part A (Epoxy Resin Section) various types of epoxy resins, epoxy novalac, epoxy resins of very low molecular size and weight, plasticizers, aliphatic and aliphatic epoxy resins, thixotropic agents, degreasers, mineral and organic additives. Part B (epoxy hardening section) also consists of a variety of amino hardeners – aliphatic, cyclo-aliphatic, aromatic, anhydride, mercaptan, manish bases, polyamides, amidoamine, and inorganic and organic additives.

Properties and advantages of two-part epoxy adhesives

Two-part epoxy adhesives, as a versatile structural adhesive, have the highest consumption in various industries due to their ability to bond different types of surfaces to each other, very high strength, chemical and environmental resistance.

These adhesives have the ability to permanently bond with a very high strength at various levels in the industry

  • Resistant to vibration and shocks
  •  Electrical insulation
  • Resistant to temperature cycles
  •  Peripheral curing
  • The ability to fill in the cracks
  • The ability to permanently connect heterogeneous surfaces
  • uniform pressure distribution
  • Lasts for at least 50 years
  • Ease of use and installation
  • Completely solid and solvent free
  •  Chemical resistance in alkaline and acidic environments
  • Resistant to corrosion in adverse weather conditions
  • Protective cover against moisture and sunlight

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

Applications of two-component epoxy adhesives in various industries

These adhesives are used in most industries due to their high mechanical and chemical properties:

In the civil engineering and construction industries

To bind all kinds of building materials together for life and permanently, they are used to repair and strengthen all kinds of bridges, structures, concrete, steel, mortar and polymer anti-corrosion fillers.

In the electrical and electronics industry

Since epoxy adhesives are electrically insulating, they are used in the production of various electrical components and structures (transformers, etc.)

In the aviation and aerospace industry

Due to the very low strength-to-weight ratio, epoxy and epoxy adhesives are used in aircraft and vehicle parts.

In the oil, gas, petrochemical and marine industries

Due to the very high resistance to abrasion, epoxy adhesives are used to repair and rebuild, bond parts to each other for life and repair the leakage.

Two-component epoxy adhesives selection agents

One of the most important factors to consider when choosing an epoxy adhesive is the work life of the epoxy adhesive. It is important to know when the epoxy adhesive has dried and hardened, or when internal chemical reactions are complete and the adhesive has reached its final strength. There are two concepts in terms of time of use. One is the time it takes for the adhesive to change from a liquid to a solid state, and the other is the time it takes for the adhesive to reach its final strength in most chemical chains.

The application temperature of the adhesive, the environmental chemical conditions, the amount of temperature and mechanical shocks to the adhesive are other important information that must be chosen carefully in the appropriate adhesive.

Another factor to consider when choosing a suitable epoxy adhesive is the surface material. Even if two-part epoxy adhesives are generally suitable for all surfaces from metal to plastic, glass and wood, special epoxy adhesives have been developed for each.Some samples of epoxy binders are currently being produced, such as electrode epoxy. Epoxy adhesive designed for electrical molds. The important thing about electrical molds is that the electrode epoxy is highly resistant to shock and vibration and resists moisture to prevent corrosion. Epoxies are very good insulators of the flow of electricity, so they are used in the production of printed circuits, circuit surface insulation, hybrid chips and transistors.Adherence to proportions, complete cleaning of the surface from grease, dust and any contamination and removal of hidden moisture are important factors so that when using epoxy, the epoxy never separates from the surface.Color is also an important factor to consider when deciding on an epoxy adhesive. The epoxy adhesive must be aesthetically pleasing to the surface coating. Fortunately, two-part epoxy adhesives are available in a wide variety of colors, even for those difficult to match, and they are also available in transparent form.

conclusion

Epoxy resin contains a wide range of mesh-related products. Epoxy can be formulated for different uses. Today, due to the cost-effective properties of this material compared to other materials, its consumption has become widespread and will increase over time.In this article, Megatite Group tried to inform you scientifically and professionally about the molecular structure of epoxy, types of epoxy resin, properties and advantages of epoxy resin adhesive, as well as its application in various industries.Have you ever used epoxy resin?
