What do you need to make resin keychains?

Keychains are among the most popular and common promotional items. And that’s understandable. Small, lightweight, and inexpensive, they can be used for locating your belongings, taken as souvenirs from around the world, or given as wedding favors.

Making your own resin keychain is easier than you think, and a lot of fun! Learn what you need to make resin keychains and let’s get creative! It’s more likely that you’ll find your keys easier when an attractive keychain is attached to them.

Getting started

Supplies you need to create resin keychains:

  • Roxy Epoxy Resin 16 oz Kit (includes separate bottles of epoxy and hardener, measuring cups, disposable gloves, wooden stirring sticks, and a 24 color set of mica 5g powder bags)
  • Silicone molds
  • Jump rings
  • Jewelry chain
  • Jewelry pliers
  • Keyrings
  • Some accessories you’d like to add: glitter, flowers, buttons, etc.
  • Hand drill
  • Sandpaper

How to mix epoxy resin

To obtain the perfect epoxy resin, all you need to do is follow these 3 simple steps:

  1. Heat the resin prior to use. To do so, place both bottles included in the kit in hot water for 30 minutes at a temperature of 122°F (50°C). This will help the resin mix nicely and avoid air bubbles. After the contents of the bottles have warmed up completely, let them cool down until they have returned to room temperature. Warning: Handle hot water with caution. Do not bring water to a boil (212°F/100°C).
  2. Pour equal parts of resin and hardener into the measuring cup. Using a clean stick, mix thoroughly for 3-7 minutes until the mixture becomes transparent. At this stage, you can add powder colors if you wish.
  3. Pour the composition into the shape or surface of your choice and let it dry for at least 24 hours in a dust-free environment.

How to make your own keychains (with flowers)

Flowers can beautify any object. You can either buy sheets of dried flowers at craft stores or online or choose to dry them yourself. If you choose to buy them from a retailer, keep in mind that the flowers need to be small enough to fit within the chosen mold. If you choose to dry them yourself, you can use the hang dry method: gather your flowers into small bouquets and hang them upside down for two weeks in a dark place, where children or pets cannot reach them.

After you’ve mixed the epoxy resin accordingly, follow these next simple steps:

  1. Pour a small amount of resin into the mold. If you are using letter-shaped molds or other molds that have corners, use a wooden popsicle stick to spread the resin into each of the nooks and crannies. Go about halfway with the resin, without filling the molds completely.
  2. At this stage, position the dried flowers inside the mold using tweezers. Press down on them with the tweezers to secure them to the resin. 
  3. After that, pour more resin into the molds to cover the flowers, filling it up to the rim. If the resin in your cup has already hardened by the time you've added the flowers, just mix a new batch of resin. If you were quick and the resin is still in liquid form, then you're good to go.
  4. Allow the resin to harden in the mold for at least 24 hours before removing them. If needed, you can sand the edges of your project with 120-grit fine sandpaper so the surface and corners are smoother.
  5. Using a hand drill, drill a small hole at the top of your DIY keychain. Only drill about an eighth of an inch. 
  6. Now it’s time to screw an eye screw into the hole you just made.
  7.  Lastly, attach keychain hardware to the eye screw, securing them with pliers.

How much resin do I need for a keychain?

The amount of resin you need depends on the project you want to create. For a small keychain, 15 ml (0.5 oz) of clear resin with an equal amount of hardener is sufficient for the first layer. After adding flowers, glitter, or other objects, you can fill up the rest of the mold with a second batch of resin in the same amounts.

Problems that can arise and how to fix them

Why are my resin keychains cracking?

One of the most common reasons for cracks in epoxy is that the epoxy is at a temperature that is too high while curing. This can cause the mix to cure faster, but unevenly, and eventually break.

To fix cracking at the surface, you should be able to sand down and fill any imperfections with a second batch of epoxy. If the cracks are inside the epoxy, you can cut around the crack to get rid of it, then sand and repour a top coat.

How can I get rid of bubbles?

When working with resin, bubbles often arise due to a number of factors: cold temperatures, inaccurate mixing, or pouring epoxy that’s too thick.
