ED-20 resin properties and application

The transparent, viscous liquid Epoxy-diana resin ED-20 has a yellowish brown color and is free of inclusions and mechanical impurities. Based on epichlorgidrin and diphenylollpropan, it is a smooth reactionary product. This brand’s resin supplier is known to them as FKP Plant. Sverdlova, a number of other businesses also produce it. The material’s designation stems from the average mass fraction of 20% that epoxy groups have in the resin.

Several hardeners are mixed with ED-20; in certain situations, plasticizers must also be added (to reduce the rigidity of the finished product). Curliness can be achieved both hot and cold (at room temperature or above); press and thermal equipment are not needed for this process. The following are ED-20’s characteristics:

• high density, unorrostity of the finished product;
• excellent hardness, resistance to mechanical damage, aggressive environment, moisture effect;
• heat resistance;
• dielectric and anti -corrosion abilities;
• good adhesion with plastic, metal, glass, ceramics, wood, kevlar, carbon fiber and many other materials;
• ease of work;
• small shrinkage, low proportion.

The national economy uses epoxy extensively in many different sectors. It is employed in the manufacture of furniture, such as tables and chairs, as well as in the repair of electrical engineering, computers, radio electronics, yacht and boat parts, and houses.

They create gorgeous countertops, galleries, and bathroom products with the aid of ED-20. The content is appropriate for the mechanical engineering, instrumentation, construction, and aviation industries. Its application to bulk floors and wall coverings supports the most audacious design concepts.

A variety of paints and varnishes, including primers, enamels, impregnation varnishes, and baying mixtures, contain ED-20. Reinforced plastic, fiberglass, and fiberglass are made using epoxy.

This article will give a thorough explanation of ED-20 epoxy resin, emphasizing its salient features and providing helpful advice for using it successfully.

Analogs of the material

There are several epoxy resins from the ED, TEG, and KDA groups that are comparable in terms of their components, qualities, and applications. They can take the place of ED-20 if needed. These are the most well-known resins.

Ed-8

GOST 10587-84 is followed in the production of Epoxy ED-8. It is a soluble fading oligomer made of the same ingredients as ED-20, which are epichlorgidrin and diphenilollpropan. Smol is widely used in a variety of industries, including aviation, shipbuilding, machine building, paint and varnish manufacturing, construction sites, equipment repair, and electronics manufacturing. Additionally, the epoxy connects the reinforced plastic pieces.

Indicators of physico-chemistry-wise, ED-8 and ED-20 are similar. Sophisticated chlorine and chlorine ions have comparable contents, but the mass does not contain any hydroxyl groups. Both the softening temperature and viscosity are the same. The primary variations are in the gelatinization time (3 hours) and mass fraction of epoxy groups (8%).

ED-16

The properties and application of epoxide resin ED-16 are identical, but it contains approximately 16% fewer epoxy groups. Because the product has a lower viscosity than ED-20, desilation happens more quickly (about 4 hours). The tool has a higher chlorine content but is distinguished by strong glue seam indicators.

Ed-22

Another epoxy has a 22% share of epoxy groups and is based on epichlorgidrin and diphenylollpropan. Among its features, ED-22 resin has a longer gelatinization time of eighteen hours and a dynamic viscosity of eight to twelve pa/second.

E-40

The technology used to create E-40 epoxy varies slightly from that used to create the materials under the ED brand. Epichlorgidrin and diphenylollpropan are condensed in an alkaline environment with the addition of toluene solvents to produce the product. Polycarbon acids, their anhydrides, and polyamins are examples of hardeners that can be used to translate the tool into a non-melting state.

The material can be used to prepare enamels with strong protective qualities and to make putty and varnishes. Furthermore, the E-40 serves as a semi-finished product in the production of various epoxy resins, filling compounds, and adhesives. High plasticity, moisture resistance, and resistance to moderately aggressive acids and alkalis are among the qualities of the polymerized resin.

Instructions for the use of ED-20

The outcome of combining hardener and resin will be significantly influenced by their ratio, the surrounding environment, how well the container was prepared, and a number of other specific elements. The usage instructions typically just list the precise component ratios and prerequisites needed to complete the polymerization process, rather than providing step-by-step instructions. If the liquid hardener isn’t included in the kit, it’s advised to purchase one beforehand and combine it with resin in the smallest possible amounts. This will enable you to observe the outcome and make judgments regarding the accuracy of the proportions.

Resin mixing in tiny amounts is not represented by difficulties. Cold curing technology works best for this purpose when everything is done at room temperature. Since the method of hot curing is employed, you will need to set up the dishes for heating the resin before mixing the epoxy in large quantities. After the epoxy has warmed up to between 50 and 55 degrees in a water bath, more work is done more quickly.

It’s crucial to remember that once the hardener is added, the polymerization reaction cannot be stopped and can only be slowed down by slightly lowering the surrounding temperature. Erroneous execution will result in the epoxy portion spoiling, so all calculations need to be done beforehand.

Preparation of resin

For cold curing, no special preparation of the material is required. For a hot method and accelerating the impregnation (fill), it is recommended to heat the measured portion of the product. To do this, install a water bath, have a container with epoxy resin on it. It is important to ensure that not a drop of water penetrates the mass, this will ruin it. It is also impossible to overheat the material, the reaction will go too fast, and bringing to a boil will bring the resin to unusable. It will be optimal to heated up to 55 degrees or less. You can completely lower the container with the material in dishes with hot water, let stand without boiling water. Mix the mass periodically for the uniformity of heating.

Epoxy has the potential to crystallize when stored or used beyond its shelf life. Make sure there are no crystals or muddiness in it before heating it to +40 degrees and thoroughly mixing it. In doing so, the material transparency will be restored.

Using the plasticizer

Several additions will aid in the plasticization of epoxy resin. Why is it required? The product’s elasticity needs to be raised if it is to endure high shock or other mechanical loads in the future, such as an effort on a fragment using a lever. These kinds of loads can be partially extinguished by adding special plasticizers. In the event that epoxy is used for both filling and gluing, they are also advised to improve the elasticity of the joints.

Plasticizer DBF

The most widely used plasticizer for epoxy is dibutylftalate, or DBF. It is added in tiny amounts, up to 2–5% of the total volume. Products can be shielded by the product from frost and impact damage. Introducing DBF is particularly demonstrated when utilizing PEP and TET hardeners. Plasticizer does not need to be added if the hardener is used to a 45-degree angle. One drawback of the DBF is that it requires a lengthy mixing and heating process due to its intricate resin connection.

DEG PLAG 1 and TEG 1

Dietilen glycol, or DEG 1, is a plasticizer that can be used to dilute the bulk but is also an epoxy in and of itself. The ED-20 working concentration is 3–10%; the more product added, the more rubber-like the resin will be. If colorlessness is not a concern, DEG-1 is much simpler to use and is readily attached to epoxy. Owing to its orange tint, this plasticizer isn’t appropriate for every situation.

Tag 1 is similar to DEG 1 in terms of properties and application, but it is slightly more viscous and has a brown or yellow color. The primary compositional difference is that TEG 1 contains triatilen glycol in place of dietalen glycol.

Using hardener

A complete participant in the chemical process of epoxy resin polymerization is a hardener. Plasticizers are added first, and then it is added to the mass. Epoxy should be no hotter than 30 to 40 degrees when mixing it with a hardener to minimize the risk of boiling.

Generally speaking, one part hardener to ten parts resin is the ratio, but other factors, like the final product, will determine the exact ratio. Sometimes a ratio of 20:1 suffices, but other times a ratio of 5:1 is necessary. Because the start of the thermal reaction can result in overheating and damage to the resin, the hardener is added to the main mass very gradually. Rapid infusion typically results in an instantaneous freezing of the mass, causing an avalanche-like process. Excessive hardener and high epoxy initial temperature can have similar effects.

PEPA, TETA and DETA

PEP, also known as polyethylene polyamine, is a cheap and widely used hardener that doesn’t require heating the initial mass and can be used at room temperature or below. Even in situations with high humidity, PEP maintains its characteristics. It is based on ethylene amines and has a yellow, brown, and occasionally greenish color. 13.7% is the ideal amount to add to epoxy; it’s crucial to stay within the range of 10% to 15%.

Another well-known traditional hardener that works well at +15 to +25 degrees is called Trietilentetramin Teta. The substance’s toxicity and caustic odor are among its drawbacks. Strict adherence to proportions is necessary (though not as much for PEP).

The deate hardener is a part of the same class of materials used in epoxy resin cold polymerization. The gravity of moisture and carbon from the air is a distinguishing feature, so it needs to be stored tightly closed. Resin is hardened in 1.5 hours by this product.

The standard 45m

Because of its "given plasticity," this universal hardener doesn’t need plasticizers added. Its consistency is similar to that of the ED-20 resin, making mixing simple. The addition of the 45m standard results in a less violent temperature reaction. It is also non-toxic, does not trigger allergies, and has no disagreeable odor.

The viability of the epoxy

The term "life time" refers to the amount of time that the mass remains liquid or viscous following the addition of the hardener. The epoxy is suitable for use at this time. Similar to hardeners, different resins have varying vitalities. This indicator typically shows 30 to 60 minutes.

The lifetime of a PEP added to ED-20 ranges from 30 to 50 minutes, depending on the hardener concentration and temperature. The duration of complete polymerization ranges from a day to several days. Three times more viability and full polymerization are equally convenient for the master for the 45 m standard.

Miscellaneous quality of gluing

The brand of the plasticizer or hardener can have an impact on the epoxy’s quality. The final product will meet the requirements more when costly and potent additives are used. Thus, don’t skimp on quality and opt for the cheapest fillers.

Packaging, storage and transportation

Epoxy resin is packaged in drums weighing between 50 and 220 kg as well as in cans, which are plastic containers weighing at least 0.5 kg. Deliver the medication for covered delivery. Material may be stored at +15 to +40 degrees, tightly sealed, and away from direct sunlight. It cannot be kept in close proximity to oxidizing agents or acids.

The exceptional durability and versatility of the ED-20 brand epoxy resin set it apart and made it a popular choice for a wide range of applications. Its exceptional mechanical robustness, chemical resistance, and adhesive strength are among its special qualities. These qualities guarantee that ED-20 epoxy resin can easily manage challenging tasks and environments.

The capacity of ED-20 epoxy resin to form robust bonds with a range of surfaces is one of its primary characteristics. Because of this, it is perfect for a wide range of industrial and do-it-yourself projects, from coating and sealing to crafting and repairs. Because of its chemical resistance, it can also be used as a dependable barrier against corrosion and damage in environments where exposure to harsh substances is a concern.

To get the best results when using ED-20 epoxy resin, careful attention to mixing and application procedures is needed. It is imperative to adhere to the manufacturer’s instructions regarding the appropriate resin-to-hardener ratio and the suggested curing conditions and times. To guarantee the best adhesion and finish, proper surface preparation is also essential. This includes cleaning and roughening the surface.
