How to Add Colour to Epoxy or UV Resin

← Back to What is resin thickener used for?

Adding colour to resin is a wonderful way to make your creative projects stand out. By choosing the right pigments or dyes, you can achieve beautiful, vibrant effects in both epoxy and UV resin pieces.

Choosing the Right Colourant

Always select colourants that are clearly marked as compatible with your chosen resin type. Some pigments and dyes, like Colourfun, can be used safely in both UV and epoxy resins. However, avoid water or alcohol-based colourants unless your resin’s guidance specifically confirms compatibility, as these may cause issues with mixing or curing. When using clear artistic resins such as Art Pro Deluxe, stick to recommended resin pigments for best results.

Mixing Techniques for Even Colour

To achieve an even finish, add the pigment slowly to the mixed resin and stir well, scraping the sides of your container to avoid streaks. Start with a small amount of colourant and gradually increase until you reach the desired opacity. For UV resins, thin layers ensure proper curing, so adjust the amount of colour accordingly to keep layers transparent enough for light to pass through.

Practical Tips for Consistent Results

Mix colour into the resin after combining resin and hardener, not before.
Test a small batch first to check compatibility and effect.
Avoid adding too much pigment, as this may affect curing or cause cloudiness.

When This Matters Most

Selecting the correct colourant is especially important for intricate art projects where clarity, vibrant colour, and a reliable cure are crucial. Jewellery, geode designs, and coasters particularly benefit from careful pigment selection and mixing.
