What Is Resin?
If you find yourself asking that what is resin? And you notice different mixture of colors on the handle of knife then you are already halfway there.
What is resin? Put simply, resin is a thermoplastic that happens to be extremely resilient and versatile. However, before we get into the specifics let’s have a look at how resin came to be and why it was invented in the first place. Resin came to be in the late 1930s when scientists were experimenting with both naturally occurring resins like those found in the bark of trees and purely synthetic resin variants.
These resins were some of the earliest ever discovered and did not closely resemble the store-bought resin that we know today. Epoxy resin in particular skyrocketed in popularity around the early 1940s, as the formula was patented and was used in applications like dental prosthetics, industrial-grade adhesives, and even crude forms of resin casting as time went on.
During the late 1940s epoxy resin and its subsequent applications were becoming pretty well known both in the scientific community and among artists, both of which use epoxy to push the boundaries limits of their respective crafts to new heights. It was around this time that new compositions of epoxy were being developed for various other applications too.
How does resin work though? Well, generally speaking (as there is more than one type of resin) resin consists of a resin polymer that when combined with a catalyst (or hardener) undergoes a thermic reaction which causes the resin to solidify into a form of your choice by use of a mold.
What Is Resin Made Of?
What is resin made of? Well, if your only exposure to the world of chemical engineering is through television or high school chemistry class, you can rest assured that you’ll still be able to understand this perfectly. Epoxy resin specifically, is created when acidic hydroxy groups interact with a substance called epichlorohydrin.
When these two chemicals interact with one another the resulting epoxy is known as glycidyl-based epoxy resins. There are other types of epoxy resins that can be made by adding different substances to base chemicals to form a ploy (or resin) with specific characteristics. These characteristics can then be alerted or improved for certain industries and applications.
Conventional epoxy resin, the kind that you would buy at crafting stores has some inherent qualities regardless of brand and or price. Some of these qualities include being completely food safe once they have had a chance to cure completely, being highly resistant to the effects of heat and open flames, and of course the ability to absorb impact and abrasion while insulating a surface.
How is resin made exactly though? Well, tree resin is a simple chemical reaction that takes place when a tree is injured. The plant will secrete the transparent substance which seals the orifice created by the wound. Synthetic resin on the other hand is a bit more complicated to make, well at least to us humans who can’t secrete resin. Synthetic resin is made when hydrogen, oxygen, sulfur, and carbon atoms are combined with a chemical catalyst to produce the resin we use today. How is resin made, then?
Benefits Of Resin
- Resin is a good choice for a handle knife since it can withstand temperature changes.
- Resin is one option for creating a durable handle that is resilient to damage.
- Knife handles made of Resin are also more rot-resistant.
- Resin knife handles are highly machine-able and often do not require finishing. The material also feels good.
- This knife handle type is aesthetically pleasing. The combination of the colourful designs of resin are all fantastic. It adds flair to the overall knife look.
