Epoxy Dome: Clear Resin Layer for Pins

When designing enamel pins, one finishing option that often sparks curiosity is the epoxy dome. Epoxy is a clear resin coating that's applied over the surface of a pin. It creates a glossy, protective finish — almost like a glass bubble. While not used as often in high-end collector pins, epoxy dome has unique benefits and design opportunities.

In this guide, we'll explain what epoxy domes are, when to use them, their production limits, and creative tips to get the most out of this option.

✨ What Is an Epoxy Dome?

An epoxy dome is a clear layer of resin applied to the surface of a pin after plating and coloring. Once hardened, it creates a smooth, rounded finish that sits slightly raised above the pin's surface.

Think of it as a transparent shield:

• Protects the enamel and design underneath.

• Adds shine and depth.

• Creates a slightly magnified look, enhancing certain details.

🎨 Why Use Epoxy in Pin Design?

Epoxy domes aren't standard for traditional enamel pins, but they work well in specific cases:

1. Printed Pins

   • Epoxy is often used to protect printed designs, since printing is more delicate than enamel filling.

   • Prevents scratches, fading, and color wear.

2. Special Effects

   • Adds a glossy, glass-like finish.

   • Can make logos or text appear bolder and more vibrant.

3. Photography & Art Reproductions

   • Perfect for pins that use detailed images or gradients.

   • Epoxy locks in small printed details that enamel can't replicate.

4. Budget-Friendly Options

   • Often used on less expensive pins or giveaways, since epoxy can replace enamel filling for simple designs.

🛠️ Production Limits of Epoxy Dome Pins

Before deciding to use epoxy, keep these manufacturing limits in mind:

1. No Texture

   • Epoxy creates a smooth dome, which removes the raised/recessed texture of soft enamel pins.

   • If you want that tactile, detailed look, epoxy isn't the right choice.

2. Detail Size

   • Works best on larger, flat areas. Small details may appear blurred or distorted under the dome.

3. Shape Restrictions

   • Epoxy spreads naturally. Very thin lines, sharp edges, or cutouts may cause uneven coating.

   • Best suited for standard shapes (circles, rectangles, solid silhouettes).

4. Durability Limits

   • While epoxy protects against scratches, it can yellow slightly over years if exposed to sunlight/UV light.

   • Enamel without epoxy generally lasts longer for collectors.

5. Not Ideal for Premium Pins

   • Most collectors prefer hard enamel or soft enamel without epoxy, since epoxy has a “merch” feel rather than a fine jewelry-like finish.

🌈 Design Tips for Epoxy Dome Pins

• Choose bold graphics: Large, high-contrast designs work best.

• Leverage prints: Use epoxy to protect designs with full-color printing, gradients, or photo-quality art.

• Think about function: Epoxy adds durability, making it great for keychains or zipper pulls where pins face more wear.

• Avoid overly intricate outlines: Simple silhouettes help epoxy spread evenly.

• Highlight logos: Epoxy domes create a glossy, professional look for branding pins.

✅ When to Use Epoxy (and When Not To)

Best for:

• Printed pins or gradient artwork.

• Logo pins, promotional pins, or giveaways.

• Designs where durability is more important than texture.

• Keychains, magnets, and accessories that see heavy use.

Avoid for:

• Collector-grade enamel pins.

• Designs relying on fine linework or textured contrast.

• Pins meant to feel premium or jewelry-like.

💡 Final Thoughts

Epoxy domes aren't for every design — but when used intentionally, they can be a powerful tool in your pin-making toolbox. They offer durability, protection, and a glossy finish that makes sense for printed designs, logos, and everyday-use accessories.

If you're planning a pin that needs to withstand wear and tear, or you're working with full-color printed designs, adding an epoxy dome could be the perfect choice.
