Why Acrylic Flatbacks Work in Resin
Acrylic flatback charms are a popular choice for resin crafts because they are lightweight, colorful, and easy to embed. The flat back allows them to sit flush against the surface of your project, whether you are making resin jewelry, coasters, or keychains. Because they are made from 100% acrylic, they are generally compatible with epoxy resin, but there are a few things to keep in mind to get the best results.
What the AT271-Happy Hallothanksmas Flatback Tells You
- AT271-Happy Hallothanksmas-Acrylic Flatback: Material: 100% Acrylic Acrylic is a stable plastic that typically does not react with epoxy resin, making it suitable for embedding without clouding or melting.
AT271-Happy Hallothanksmas-Acrylic Flatback - AT271-Happy Hallothanksmas-Acrylic Flatback: Colors may vary due to lighting. I try my very best to capture the true colors. The actual color of the flatback may differ slightly from the product photo, which is important to consider when matching colors in your resin project.
- AT271-Happy Hallothanksmas-Acrylic Flatback: There may be imperfections due to the manufacturing process Minor surface imperfections are normal and may be visible under clear resin; you can sand them lightly or hide them with a resin coating.
How to Embed Acrylic Flatbacks in Epoxy Resin
Start by preparing your resin according to the manufacturer's instructions. Pour a thin base layer into your mold or onto your surface and let it partially cure until it becomes tacky. This helps the flatback stay in place without sinking. Gently press the flatback charm into the tacky resin, flat side down. Then pour a second layer of resin over the top to fully encase the charm. Avoid trapping air bubbles by using a toothpick to nudge the resin around the edges of the flatback.
Because the flatback is acrylic, it will not absorb resin, so the bond is mechanical rather than chemical. Make sure the charm is fully covered to prevent it from lifting later. If you are using the flatback on a curved surface like a cabochon pendant, you may need to apply a small amount of resin or glue to the back before placing it.
Design Ideas for Your Resin Project
Acrylic flatbacks work well as focal pieces in resin jewelry, such as pendants, earrings, or bracelet links. You can also scatter multiple small flatbacks in a resin coaster or tray for a playful look. Because the flatback has a flat profile, it sits neatly under a resin dome without creating a bulky bump. For a layered effect, embed the flatback between two layers of tinted or clear resin.
Keep in mind that the flatback's design may have small details that can be obscured by thick or dark resin. Test a sample first to see how the color and pattern look when submerged.
Practical Trade-Offs to Keep in Mind
Acrylic flatbacks are not food-safe and should not be used in items that come into contact with food or drink. They are also not intended for use by children under 3 due to choking hazard. The colors may vary between batches, so order enough for your project at once. If you are unhappy with the product, contact the store within 48 hours of receiving your order, as the item is non-refundable after that window.
For best results, work in a well-ventilated area and follow all safety guidelines for epoxy resin. The flatback itself does not require any special preparation, but a quick wipe with a lint-free cloth can remove dust before embedding.
