Working with different types of resin can be useful for certain projects. These can be used as epoxies, or they can be molded and fitted to form various shapes like clay. Resins can also be used as natural adhesive options, as they have the ability to blend seamlessly with your surface once dry. In this article, we are going to discuss the different types of resins and how they are used.

Understanding the Different Types of Resin
There are a few different uses and types of resin. Deciding on which one to use is based on the type of resin you pick as well as the job you are intending to use it for. One rule that applies to all different types of resins is to always wear a mask, as these materials give off dust particles that can be very harmful if inhaled. Different types of resin include the following:
Let us explore each of these in detail below.
Types of Epoxy Resin
Types of epoxy resin are a more common and versatile choice of resin for most projects. This option is highly durable and will give you the longest-lasting results. These are quite thick and produce layers of up to five millimeters each. So, quite a bit more than your UV resins. However, they do not hold up well in high-moisture conditions.
Using types of epoxy resin may be a bit more time-consuming as they usually come in a double pack with two products (a resin and hardener). You need to mix up both products before you can apply it in order to elicit the chemical reaction that results in the resin hardening. As they are so thick, they will take longer to dry and will need at least three full days to cure completely.
Also known as laminating resin, this type of epoxy resin is used for sealing and coating objects. This resin has a high viscosity, meaning that it is very thick and will therefore leave a durable and high gloss finish on your surface. Coating resins are a wonderful sealant option for concrete and other porous surfaces.
This type of epoxy resin is often used for making molds and casts of small-scale objects. Due to its thinner consistency, it dries fairly quickly and will do a great job at easily filling holes in certain surfaces. This resin is used more for jewelry making, molds for figurines, and even in dentistry.
Using Other Types of Resin
Depending on what you are using the various types of resin for, the application method may vary. If you are using it to coat a surface, you will need to apply the resin in layers, ensuring that you allow for sufficient drying time between each coat. This resin can also be sanded over between layers to ensure smoother results. Sanding should not need to be done after the second layer. These resins take a long time to cure, but are touch-dry relatively quickly.
This resin option is pretty different from the other types of resin available. UV resins do not dry on their own as other options do. They will remain wet until exposed to a source of ultraviolet light or irradiation. Using a UV lamp is the simplest way to do this. This will effectively cure your resin and is perfect for smaller projects and areas. This choice is also much thinner than other types of epoxy resin, thus creating layers up to a thickness of 1 mm.
When choosing to use a UV option, you should be aware these are not the most durable. These resins will need to be re-applied and touched up twice a year for proper maintenance, and will not protect your surface from damage or heat.
Using a UV Resin
Applying a UV resin is as easy as painting it over your surface. For added effects, you can also add in colors or tints to it in order to create interesting designs and patterns. You will then use your lamp to start the drying process. The strength of your bulb should be a minimum of four watts to work effectively. This should not take longer than five minutes. If you would then like to add more layers, you can. Be sure to wear a protective mask as even when dry, these fumes are toxic.
Synthetic Polyurethane Resin
This type of resin is part of the synthetic group, which makes it a great choice for making molds. These have more of a plastic consistency, which aids in their flexibility and their ability to be manipulated. This also makes this type of resin stronger at resisting scratches and less likely to turn yellow. These are usually used for flooring, paints, coatings, and adhesives.
This resin option is a great choice when wanting to protect outdoor areas or even cables from moisture and other elements. Polyurethane resins work with the same two-part process as types of epoxy resin. This means that you will need to be careful when combining the products so as to ensure you have the correct ratios. Although this resin option is waterproof when dry, it will not work if applied to a wet surface.
Using a Polyurethane Resin
Because this solution is so versatile, the method used will be based on what you are doing with your resin. If you are thinking about creating a mold, you would mix your product up according to the product directions and then apply it to your mold.
Polyester Fiberglass Resin
Polyester resins fall under the types of fiberglass resins, and these are used for bigger jobs. Because of its waterproofing properties, it can even be used outdoors. Commonly, polyester resin is used for building ponds, pools, and other watercrafts. This resin can also be used to build models such as boats, planes, and cars.
Using a Polyester Resin
Just like our other two-part resins, the same will need to be done when using your polyester option. The key here is consistency when adding your elements and making sure you have the correct product ratios for optimum results. This mixture can be used for laminating or making molds. When using these types of fiberglass resin, you will need to use fiberglass sheets and mats in order to get the ideal shapes and molds you are after.
There you have it – all the basics on the different types of resin out there and what you can use them for. Have fun with your projects!
Frequently Asked Questions
What Types of Resin are There?
There are a few kinds of resin one can use based on the purpose of one’s project. Some resins work best for indoor projects, as they will not protect your surface from heat and moisture. Others work well as sealants or for outdoor applications.
Are There Different Types of Epoxy Resin?
Types of epoxy resin do not differ that much, but their differences allow for more versatility. Normal epoxy resin can be used for many things including making jewelry, or it can also be used as an adhesive. casting resin and coating resin are also types of epoxy resin. Casting resin is great for making figurines and small molds, while coating resin works well for high-gloss finishes outdoors.
What are the Different Types of Resin Used For?
There are different types of resin for different uses. If you are looking at sealing and coating your floors, then you may like to try a polyurethane resin for a quick application that is scratch-resistant. If you are looking at building an outdoor pool or sealing a small boat, then choosing types of fiberglass resin would be ideal for the job as they are waterproof when cured. The type of resin you choose will be based on your project requirements.
