2 Major Types of Resin, and Their Pros and Cons
Perhaps you already heard or seen artworks or home décor made from resin. Amber is an example of nature-made resin. However, the resin also comes in synthetic form and is made into different arts and crafts, jewelry, and home décor, among a few. Ancient cultures have different beliefs and usage of resin.
But one thing is for sure: resin is a fascinating material and more fascinating with its wide variety of usage then and now. You can also find a lot of home décor and other creative crafts in gifts, crafts, and home décor stores near you. This article will explain what resin is, where it comes from, and its broad usage.
What is resin?
First of all, there are natural and synthetic resins. Plants and trees secrete natural resins as a defense mechanism for protection against pests. Synthetic resins, on the other hand, are liquid compound that hardens and is often used for jewelry and DIY art and craft making. Synthetic resins are either made from epoxy or polyester, and are used for coatings, composites, and adhesives, for commercial and personal use.
As mentioned, there are two types of resin – either made with epoxy or polyester. These two resin types vary in their hardening process as well as their structural, adhesive, and protective properties. Other factors that differentiate the two are the following:
Epoxy needs a special hardener as part of the curing process. The curing process will only begin once this special hardener has already been mixed. It is also said to be stronger and more durable between the two resin types, though polyester may be preferred depending on circumstances.
Polyester resin has already a combination of resin and hardener. However, the polyester resin curing process can be slow. This is why it usually needs to add a catalyst to speed up the curing process. This catalyst can either be through UV light application or a chemical reaction. Polyester resin also has an expiration.
Epoxy resin: Pros and cons
Epoxy resin is often used in varnishes, casting, sealants, paints, and other industrial applications. It is also an ideal material to fill in gaps as it does not shrink during the curing process. Other benefits of epoxy resin include:
- Moisture and chemical-resistant
- Has electrical insulating properties
- Can be reinforced with fibers and other enhancements
- With a high weight-to-strength ratio, making it an ideal option for resin casting
On the downside, epoxy resin is not resistant to UV rays and not water-proof. Epoxy paint may turn yellow and chalk-like when exposed to too much sun.
Polyester resin: Pros and cons
Unlike epoxy resin, polyester resin is waterproof, rust, acid, and corrosion-resistant. It is also resistant to too much heat. It is also used as powder coatings, primers for marine applications. Polyester resin has low shrinkage and a good wetting quality.
On the downside, the polyester resin may not be as durable as epoxy resin. This means you need to choose one that is waterproof or more strong. It is not also as effective in gap-filling as epoxy resin.
Resin is a useful substance applicable for personal or industrial purposes. Knowing the right kind of resin is useful especially if you are going to use it for arts and crafts. You can check these resin-made décor and accessories in a crafts store in Franklin TN to spice up your home.
