What is Resin made of – All informations and Resin History

what is resin made of


Resin is an organic compound that comes in a liquid form. When you buy resin, it comes in two separate forms that need to be mixed together to form the actual resin. These are the resin and the hardener. Mixing these two parts together creates a reaction in the resin particles which leads to the resin being able to cure. Once dried, it forms into a strong and durable plastic. Epoxy resin is commonly used in many different areas of DIY projects, crafts, arts, and for industrial purposes. If you are asking the question “what is resin and how do we use it?” then read on for a full guide below.




Epoxy Resin at a Glance

So, what is resin in a nutshell? Epoxy resin is a special substance with, particularly strong properties. This resin is known for its chemical resistance and its excellent adhesive qualities. If you are in need of a very durable resin product, then epoxy is the best option to consider. Thanks to its strong finish and good adhesion qualities, this resin can be used for a wide range of applications. What is resin used for? Below are some of the ways in which you can utilize epoxy resin:

  • Resin Art
  • Resin Crafts like Resin Tables
  • DIY projects with Wood Epoxy
  • For making electronic parts
  • Coating metal
  • Insulators for electrical parts
  • Plastic materials that are fiber-reinforced
  • Used a binder in some cement and mortar mixtures
  • An all-round Epoxy adhesive
  • Creating coatings that are non-skid
  • Creating stiff foams
  • For use in oil drilling to solidify loose sandy surfaces
  • Industrial coatings
  • Encapsulating and coating various media
  • For plastics that are fiber-reinforced


However, the list doesn’t end there. Epoxy resin is also used in sealants, varnishes, casting and caulking compounds, paints, and all sorts of other industrial applications. When curing, epoxy doesn’t shrink. This resin is also resistant to chemicals and it is completely moisture-resistant. Not only this, but the resin has electrical insulating properties and is very impact resistant. It can also be enhanced with reinforcements for even more uses.

What is the difference between epoxy and polyester resin? 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.


There are various products out there that are all forms of or are made up of, resin. These include fiberglass, superglue, and 2 part epoxy glues. Resin can also be molded and used to make toys which are then polymerized into a plastic form. This is an easier and cheaper method than using typical molten plastic.



What is Resin Made Of – Chemical Properties

To get technical, epoxy is made up of polymer resins. These polymer resins are thermosetting, with every single molecule containing a minimum of one epoxide group. In order to reach the right viscosity and consistency for the resins use, the chemical properties can be changed. 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). In order to for epoxy resins to harden, a curing agent is added – this is usually amine-based. 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.

Epoxy Resin History

What is resin made of and how did we start to use it? The first resin that was used was tree resin – like you would find in a pine. This resin was used in ancient times as a type of glue. The tree resin needs to be heated up first, and then it sets when cooled down. Thermoset resins are another type and are generally two-part resins. These are usually products of petrochemical sources.

Frequently Asked Questions


What is Resin Used for?

Resin is a versatile substance that can be used in many different ways. What is a resins purpose? It is commonly used for making durable castings, arts and crafts, flooring, countertops, and more. Resin can be used to make plastics, and it is an excellent adhesive.


Is Resin a Plastic?

Resin is different from plastic in that plastics have a more synthetic polymer makeup. Resins have some more natural properties to them and are derived from plants. So no, resin is not a plastic. However, there are special plastic resin products available.


Is Resin Made of Plastic?

No, they are different compounds altogether. What’s resin made from then? Resins have plant or synthetic origins that are convertible into polymers. Resin is not made from plastic, even though they share many similar qualities in terms of appearance.


How Strong is Resin?

Different types of resin are available with varying degrees of durability. Epoxy resin is the strongest resin, and it has been designed to withstand all kinds of intense mechanical pressures. This makes epoxy resin suitable for a wide variety of purposes.


Is Resin Harder Than Wood?

While this depends on the type of resin and the type of wood, resin is generally thought of as being stronger. Resin is often used as a protective coating over wood, and it can be used to bond two pieces of wood together with great strength.


Is Resin Stronger Than ABS?

What is a resin’s strength compared to ABS? Resin produces a greater level of tensile strength and elasticity when compared to ABS. This makes it a great product for durable and shatter-resistant purposes.

So if you were asking yourself the questions “what is resin?” and “what’s resin used for?”, this guide above should have covered everything you needed to know. Resin is a highly useful substance that can be applied to all kinds of applications. For anyone interested in DIY, arts, and crafts, knowing how to use resin can be incredibly useful.
