Epoxy Resin Definition, History, Types, Functions, Advantage and Disadvantage

by | Epoxy

Epoxy resin is both the uncured and the cured forms of resin. There are a lot of industrial interests and various uses of this resin because of its beauty and amazing characteristics. It works like glue for sticking fibers together. Tables, furniture, building appliances, jewelry, and various forms of art can be made with epoxy. Epoxy resin can make protection from water; it is waterproof.

Epoxy Resin Definition

Epoxy resin is a very high-performance adhesive. This is used for making laminated woods for decks, walls, roofs, and other parts of buildings and in many other products that need strong bonds to other elements.  

For instance; concrete or wood. Epoxy resin can stick to metal, wood, stone, glass, and a few plastics. Epoxy resins are more heat resistant and chemical resistant than glues.

History of Epoxy Resin

The word Epoxy is divided into two Greek prefixes which are “epi” and “oxy”. The word Epi means “upon” and the word Oxy means sharp. Oxy also means acidic.

Its adhesiveness has been proved and witnessed by thousands of people for 100+ years now. Yes, epoxy resin has 100+ years of history. 

The journey of Epoxy started in Russia from the 1890s to the 1930s. Epoxy’s existence was proven during the early 1890s but got its popularity during the mid-1950s.

A Russian chemist, Prileschajev first observed that olefins react with a peroxybenzoic acid which reaction formed epoxides which formed epoxy.

During the mid-1930s,  P. Shellac, a German granted a patent for preparing a polyamine with a high molecular weight. He did it by using epoxide compounds. The first epoxy was synthesized long ago, in 1936.

Dr. Pierre Castan, a Swedish, and Dr. S.O. Greenlee, an American, together, recognized the chemistry of epoxy that people still use. So, they issued a different patent by the end of the 1930s.

Dr. Pierre Castan’s work was licensed by the company Ciba which is situated in Switzerland.

So, we can say that though Ciba was the first company that commercialized Epoxy resin in the year 1946.

Aerospace was the 1st commercial field that was responsible for penetrating epoxy in 1950. Nan Ya Plastics has the patent of epoxy resin varnish and it is for laminates.

Types of Epoxy Resin

Epoxy resins are popular for their:

  1. High level of strength
  2. Lowness of shrinkage
  3. Amazing adhesiveness
  4. Chemical resistance
  5. Solvent resistance
  6. Last but not the list
  7. Very minimal cost and
  8. Low level of toxicity.

Resins are classified into various groups. One of which is Epoxy.

There is not any particular classification of epoxy but it can be divided into 3 primary classes used in composite applications. Which are:

  1. Phenolic glycidyl ethers
  2. Aromatic glycidyl amines and
  3. Cycloaliphatic.

Function of Epoxy Resin

The functions of epoxy resin are many. The use of resin can be seen from ancient times in human history. 

Now resin is widely used in households and even for commercial & industrial purposes. 

As resin has heat & chemical resistance, high film elasticity, and many strong qualities; it is well known for its versatile uses.

Epoxy resins are widely used because of their strong heat & chemical resistance, strong adhesion, and toughness. 

Because of the properties of epoxy resin, it is used for structural purposes. 

It is used for the construction of vehicles, bicycles, aircraft. 

In the electronic industry, epoxy resin is used in the production of insulators, motors, transformers, etc.

Epoxy resin is also used in painting materials. For tough, protective coating epoxy resin is a great option.

As epoxy resin has strong adhesive properties, it is used for repair objects. Fragile items such as glass, ceramics, etc. can be easily fixed with epoxy resin.

12. What is Epoxy?

Ans: An epoxy is a thermosetting polymer with special mechanical properties and resistance. For the cured end product of all of the fundamental components inside epoxy resins, the name epoxy may be used. An epoxy resin is a type of thermoset polymer formed from a monomer containing at least two classes of epoxides. Epoxy resins may be homopolymerized or curatively cross-linked into a three-dimensional network.

13. What is epoxy used for?

Ans: In the manufacturing of adhesives, fibers, paints, coatings, primers and sealers, flooring, and other items and components used in construction and building applications, these are the things in which epoxy resins are used.

14. Is epoxy dangerous?

Ans: The risk of damage sustained by epoxy resin ingestion can be considered very low. It should be said that pure epoxy resins are known as non-toxic. There is certain toxicity in the majority of curing agents in use today. But due specifically to toxicity, it needs quite a significant amount of damage.

15. Why is epoxy so expensive?

Ans: Owing to its strength and formulation requirements, epoxy is typically more costly than resin. Resin, due to its lower cost, is more common for art and jewelry making.

16. How long does the epoxy smell last?

Ans: Compared to epoxy, polyurethane floors are mostly smoother and more elastic, giving them greater resistance to rubbing, suitable for spaces such as multi-deck car parks that require high levels of foot traffic.

40. Can you epoxy over old epoxy?

Ans: Yes. A chemical bond is not feasible because the epoxy has healed, so what is called a mechanical bond is necessary. This simply means that before the next coat is applied, the cured epoxy must be lightly sanded: the first coat should have a surface that is matt, almost white.

41. Can I pour epoxy over paint?

Ans: Yeah, after it has dried completely,   Art Resin epoxy resin can be over oil paint. In any dry oil painting, it will completely bond and seal.
