Can I Add Colourants to Epoxy-based Acrylic Resins?

How to Add Colourants to Epoxy-based Acrylic Resins

You can safely tint many epoxy-based acrylic resins with suitable dyes or pigments. Epoxy-safe colourants are designed to blend evenly and not interfere with the curing process. For example, when using the Liquidissima epoxy resin, it’s recommended to use liquid or powder dyes in very small amounts—generally between 0.1% and 2% of the total resin weight—to achieve vibrant, custom colours without compromising clarity or performance.

• Always start with a minimal amount—add dye gradually until you get your desired shade.
• Mix thoroughly to ensure even colour and avoid streaks.
• Only use colourants labelled as safe for epoxy resins.

Tips and Best Practices for Colouring Resin

Different dyes and pigments will create different finishes, from opaque to translucent. Liquid dyes blend seamlessly for transparent tones, while powders can achieve more saturated effects. Once mixed, pour promptly to achieve even colour and reduce bubbles. Be mindful: excessive colourant can hinder full curing or impact the final finish, so never exceed the recommended percentages.

• Wear gloves to avoid staining your hands.
• Test on a small batch first if trying a new colourant or resin.
• For art projects or jewellery making, these techniques allow for everything from subtle tints to bold statement pieces.

When Colour Customisation Matters

Adding colour to epoxy-based acrylic resin is especially valuable for creative contexts like jewellery, casting, art projects, and decorative coatings. It lets you match your resin work to a specific design palette or produce unique, bespoke pieces that reflect your creative vision.
