Achieving rich colour while keeping domed resin clear and durable depends on careful pigment use. Here’s what you need to know to get vibrant results without risking curing problems.
Why Pigment Percentages Matter
When tinting domed resin, the amount of pigment used is critical. Adding too much colourant can affect how well the resin sets, causing cloudiness or even sticky spots. Keeping within the recommended limits helps ensure a smooth cure and the signature clarity that makes domed pieces stand out.
Recommended Ratios for Best Results
As a rule of thumb, use no more than 5% pigment by mass in your resin mix when using concentrated colour pastes like Colourfun. This keeps the resin clear and allows it to harden fully. For subtle looks, just a few drops are often enough, while stronger, opaque effects may approach the upper end of this range but should not exceed it to maintain quality and reliability.
Practical Pigment Mixing Tips
- Always weigh your pigment and resin for accuracy.
- Mix pigment thoroughly before combining with resin to ensure even colour.
- Test a small batch if you’re aiming for a new effect or intense colour.
- If needing both colour and flexibility—such as for labels or curved surfaces—consider using a flexible doming resin like Be Flex.
When This Matters Most
Sticking to correct pigment levels is essential when creating domed badges, nameplates, or decorative pieces where both optical clarity and resin strength are needed. Exceeding 5% pigment can compromise your finish and durability.
