Which Resin is Right?

Resin Pendant from SB Design

People ask me all the time, "What resin do you use?" I've really tried hard to educate myself about the different products that are out there so I could find one I really liked. The truth is, there are lots of options available. Some resins are better for certain applications than others, so it's a good idea to know the difference between the types of resins on the market.

There are basically three resin products:

1. 2 part epoxy
2. UV Resin
3. Dimensional Adhesive

1.  2 Part Epoxy

Just like the name says, this resin has 2 parts, a resin and a hardener. The resin and hardener need to be mixed together according to the directions before being applied. Many are 1-to-1 mixtures but not all, so be sure to check out the instructions!
Pros:

• Waterproof
• Permanent
• Durable
• Scratch Resistant
• Can be used for almost any type of design, including molds, casting, embedding objects
• Inexpensive

Cons:

• More challenging to use
• Can have a stronger odor than other products
• Hard to make batches for single items, generally need to pour several items at once

Examples of 2 part epoxies: ICE Resin, Easy Cast, EnviroTex
I use a product called EX-74, which is a jeweler's grade resin. It comes in larger sizes (1/2 gallon is the smallest size), so it is probably not a good choice if you're just trying resin out. I have also used ICE Resin, Easy Cast and EnviroTex. ICE Resin is usually available at jewelry stores. Easy Cast and EnviroTex are available at Michael's or JoAnn Fabrics. Of the three, I would recommend ICE Resin. It's easy to use and has a very nice finish. When I have used Easy Cast in the past I noticed my pendants have gotten a yellowish tint as they were exposed to the sun. Other artist I know who have used Easy Cast have mentioned have problems with pieces not curing if their mixture is not exactly right. I haven't had this issue, but it's something to be aware of.

2.  UV Resin

UV Resin is a one-part liquid or gel that cures under ultraviolet light.
Pros:

• Just like 2-part epoxy, it is waterproof, durable, and scratch resistant.
• Great for making single items or small batches.
• Cures quickly

Cons:

• Not good for embedded items
• More expensive than other resins

Examples of UV Resins: Magic Glos, Gel du Soleil
UV Resins are great for making small batches of items that need to be done quickly. In order for the resin to cure it has to be exposed to UV light, either from the sun or a UV light. Because every part of the resin has to be exposed it should not be used when embedding objects - the resin under the object(s) will not cure.

3.  Dimensional Adhesive
This is a one-part solution that is not technically a resin. For this product, you simply pour the adhesive over your design in shallow layers and allow to air dry.

Pros:

• Very easy to use
• No mixing required
• Low odor
• Fast drying
• Non toxic

Cons:

• Water resistant, not waterproof
• Less durable than resin
• Not scratch resistant
• May yellow over time or in sunlight

Examples:  Diamond Glaze, Crystal Lacquer
I don't particularly like this type of "resin," because it is not permanent. If I am going to take the time to create something I want it to last without worrying about exposing it to water or sunlight. That said, it is great for kid's projects or for quick designs that don't need to last forever.

Clearly not all resins are the same. It's important before you use a product that you know some key information such as:

• what kind is it?
• is it waterproof?
• how does it cure/dry?
• how long does it take to cure?

If you are going to work with 2 part epoxies I recommend purchasing your items on this great website called FEW Products. They sell only resin and resin-related products. Their prices are great and they offer wonderful advice!
