Doming and Coating with Polyurethane Resin

Selecting the Right Polyurethane Doming Resin

For doming or top-coating, always select a self-levelling, transparent polyurethane resin. A specialist formula such as the Be Flex doming resin offers flexible, scratch-resistant protection and a high-gloss 3D effect. Flexible options adhere beautifully to curved, uneven, or delicate surfaces, ensuring long-lasting clarity and resilience.

How to Apply for Bubble-Free, Glossy Results

• Preparation: Ensure your surface is clean, dry, and stable. Place items level to prevent resin run-off.
• Mixing: Follow the manufacturer’s supplied mixing ratio carefully for even curing. Stir gently to avoid introducing air bubbles.
• Pouring: Slowly pour the resin in the centre of the item, allowing it to naturally flow towards the edges. If a true dome is desired, avoid overworking or nudging the resin edge-to-edge—let surface tension do the work for a pronounced lens effect.
• Curing: Leave the coated item undisturbed, ideally under a protective cover to prevent dust, until fully set.

Practical Tips and When This Matters

If your project needs extra resilience to heat, consider a specialist like Heat Pro polyurethane resin. For outdoor-use items, opt for doming resins with built-in UV and moisture resistance. These application methods are especially important for custom keyrings, labels, medals, or badges that see frequent handling or changing environments.
