What is Epoxy Resin?
Epoxy resin (polyepoxides) is a certain type of organic compound containing epoxide groups. It’s made up of carbon chains that are linked to other elements like nitrogen, oxygen, and hydrogen. The link happens through a covalent bond. This allows elements sharing 2 electrons to bond together. As a result, the polymers become elastic and tough. This makes them ideal for various applications.
What is the name of the chemical group in epoxy resin?
So, to understand what makes up this class of chemicals, we need to understand these terms first. 1. Epoxy. Polyepoxide is an informal name for the epoxide group. Moreover, it’s used to describe the cured end products or basic components of epoxies.
What are the mechanical properties of polyepoxide?
Some mechanical properties exhibited by polyepoxides include; compression, resilience, flexion, and tensile strength. Epoxy has superior mechanical properties as compared to large diffusion resins like polyester. This enables it to resist degradation over time, making it ideal for industrial uses. 5.
How to trigger a chemical reaction?
To trigger a chemical reaction, you need to mix the resin with the hardener. Depending on the reaction type, cured epoxy will either be honey-like or more viscous. The actual molecular weight of cured compound will determine its application.
What is polyepoxide thermoset?
This makes them ideal for various applications. In simpler terms, polyepoxide is a thermoset resulting from a reaction of 2 or more compounds. This reaction radiates heat and converts the material from a liquid to a cured/ solid form.
Why is epoxy irreversible?
When it hardens, the process is irreversible! That’s because the curing process introduces a polymer chain linked by covalent bonds. Being an epoxide, epoxy is more reactive to other chemical compounds.
How to make resin art?
To undertake resin art, you need to mix the 2 components (resin & hardener) first. This triggers a chemical reaction that forms a high, clear surface after hardening. Afterward, you can sand, polish, or even paint the cured surface.
Why use heating blankets for epoxy?
This is ideal for the epoxy curing process because it’s so critical to provide even, consistent heat to help the epoxy cure properly. Large operations with loads of cash to spend may like some of the standard heating solutions. However, most businesses operate on a budget and closely watch their expenses. These businesses will probably find some of the newer technology, like heating blankets, to be the ideal choice.
What is epoxy resin?
Or in other words, epoxy resin is epoxy adhesive in its liquid form. For any epoxy, there are two primary parts to the equation: the resin and the curing agent. When the resin and the curing agent react together, the hardening process ensues.
What is the curing agent in epoxy?
Curing. The curing agent plays a big role in how the epoxy turns out when it’s cured. There are numerous curing agent recipes, but one of the more common is a combination of amides and polyamides (which amounts to a variation of ammonia—the difference being the replacement of a hydrogen atom with a carbon + oxygen pair).
What is resin made of?
The resin itself is made of bisphenol (and there is more than one type) and epichlorohydrin. The most common type of bisphenol is a combination of acetone and phenol. Maybe you’re asking yourself now: where on earth does phenol come from? Well, when first it was discovered it came from coal tar, but nowadays, chemists extract it from petroleum (like so many other useful compounds). Now as far as epichlorohydrin is concerned, well, it’s derived from something called allyl chloride, a chlorinated subchemical of propylene.
What is the best adhesive for welding?
Epoxy is one of the best adhesives available for industrial uses. According to adhesives.org, epoxy resins, when cured, provide “rigid but tough bond lines and have excellent adhesion to metals. Chemical and environmental resistance is excellent. Most formulations have a paste consistency and can be applied by trowel or extruded as beads. They easily fill gaps and provide excellent sealing properties particularly against harsh chemicals. They are often used as alternatives to welding and rivets.”
Can you use epoxy at room temperature?
Maybe you feel like you better understand epoxy now, or maybe you don’t. But either way, you can still make use of the product for a variety of purposes. Whatever you use it for, there is one thing to remember: epoxy is temperature sensitive. In fact, most epoxies cure best at temperatures far above the normal range for ambient air. Keeping epoxy curing at the ideal temperature becomes increasingly difficult when the needle drops. But, then again, that’s why epoxy curing solutions exist.
Does heat or cold affect epoxy?
Temperature can have a significant impact in epoxy curing. Heat will accelerate curing time, while cold will slow the curing process. However, cold temperatures are preferred when storing. This is due to epoxy resins becoming less effective after warming to room temperature.
What is Epoxy Resin Made up of?
Epoxy resin is a combination of resin and hardening (curing) agent. It is thermosetting therefore it hardens when exposed to heat or radiation. After hardening, it becomes shiny and glossy. Once the epoxy is cured (hardened) it cannot be uncured.
What is epoxy resin?
Epoxy resin is a chemically created versatile substance having diverse applications in various fields. Epoxy in its liquid form was primarily used as structural and engineering adhesive in aircrafts, automobiles, ships/boats, bicycles, snowboards and skis.

With the passage of time, the use of epoxy evolved from mere adhesive to a substance that can be used in a variety of art and craft projects. How come? Let's dive into the world of epoxy.
How deep can you pour epoxy resin?
If you are selecting epoxy resin for surface coating, you should keep in mind that you can pour it up to 3/8” deep.
What is deep pour epoxy?
Deep Pour Epoxy is low viscosity resin. This resin is thin and flowable and that is why it cures very slowly.
How thick is epoxy resin?
To look crystal clear, deep pour resin needs to release more bubbles than others since it is 2 inches thick. Normally it will be formulated to have the best air release ability among all kinds of epoxy. To avoid air bubbles from the beginning, you can put a single coat of resin on the surface and then pour the deep pour resin.
What is surface coating epoxy?

How long does it take for epoxy to cure?
It takes only 4-6 hours to cure that is why it is called quick curing epoxy resin.
What is the hydroxy group of epoxy resin?
Epoxy resins produced from such epoxy monomers are called glycidyl -based epoxy resins. The hydroxy group may be derived from aliphatic diols, polyols (polyether polyols), phenolic compounds or dicarboxylic acids. Phenols can be compounds such as bisphenol A and novolak. Polyols can be compounds such as 1,4-butanediol.
Why does epoxy yellow?
Significant advances in understanding yellowing of epoxies were achieved by Down first in 1984 (natural dark aging) and later in 1986 (high-intensity light aging). Down investigated various room-temperature-cure epoxy resin adhesives suitable for use in glass conservation, testing their tendency to yellow. A fundamental molecular understanding of epoxy yellowing was achieved, when Krauklis and Echtermeyer discovered the mechanistic origin of yellowing in a commonly used amine epoxy resin, published in 2018. They found that the molecular reason for epoxy yellowing was a thermo-oxidative evolution of carbonyl groups in the polymeric carbon–carbon backbone via a nucleophilic radical attack.
How are novolaks formed?
Novolaks are produced by reacting phenol with methanal (formaldehyde). The reaction of epichlorohydrin and novolaks produces novolaks with glycidyl residues, such as epoxyphenol novolak (EPN) or epoxycresol novolak (ECN). These highly viscous to solid resins typically carry 2 to 6 epoxy groups per molecule. By curing, highly cross-linked polymers with high temperature and chemical resistance but low mechanical flexibility are formed due to the high functionality of these resins.
What is the IUPAC name for an epoxide group?
The IUPAC name for an epoxide group is an oxirane . Epoxy resins may be reacted ( cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides ), phenols, alcohols and thiols (usually called mercaptans).
How is epoxy resin made?
Epoxy resins produced from such epoxy monomers are called glycidyl -based epoxy resins. The hydroxy group may be derived from aliphatic diols, polyols (polyether polyols), phenolic compounds or dicarboxylic acids. Phenols can be compounds such as bisphenol A and novolak. Polyols can be compounds such as 1,4-butanediol. Di- and polyols lead to diglycid polyethers. Dicarboxylic acids such as hexahydrophthalic acid are used for diglycide ester resins. Instead of a hydroxy group, also the nitrogen atom of an amine or amide can be reacted with epichlorohydrin.

Why is epoxy resin added to other epoxy resins?
They are therefore added to other epoxy resins as reactive diluents or as adhesion promoters. Epoxy resins made of (long-chain) polyols are also added to improve tensile strength and impact strength. A related class is cycloaliphatic epoxy resin, which contains one or more cycloaliphatic rings in the molecule (e.g.
What is the ratio of hardener to resin?
The ratio of hardener to resin is much higher in epoxy than in other types of resins. Sometimes, thermoplastic polymers are also added to epoxy resin to strengthen it further.
What is the difference between epoxy and polyester?
The main difference is seen in the curing phase. Epoxy uses a special hardener while polyester uses a catalyst for a reaction. Epoxy resins are not all waterproof, even though they have excellent bonding properties. Some epoxy types are best kept from below the waterline.
How to prepare resin for casting?
When casting resin preparation is key. Make sure that you work in a well-ventilated space, especially when working with polyester resin. Lay down a drop cloth or some paper to protect any surfaces and set out gloves, goggles, and a respirator if your resin has a hard ener, catalyst, or initiating agent with a strong odor. If your resin requires heat to mix or set, ensure that all flammable items are kept clear of your work area.

How is polyester resin made?
While epoxy is formed when a resin is mixed with a hardener, polyester resin is the result of a chemical reaction that occurs when dibasic organic acids are mixed with polyhydric alcohols. The result is a strong plastic substance with similarities to epoxy, but also some significant differences. Since the chemical reaction that produces polyester resin requires a catalyst, the speed at which the reaction occurs can be controlled and this resin can cure very quickly. Unlike epoxy, polyester is not weakened by exposure to UV, so ultraviolet curing can be applied to polyester resin, eliminating the need for measuring and mixing catalytic chemicals.
What are the two main categories of epoxy resins?
Epoxy falls under two main categories: non-glycidyl and glycidyl. Underneath these branches, there are many sub-types of epoxies. There are two very common forms of glycidyl epoxy resins. These are novolac, and a resin which is made with Bisphenol A (BPA).
