Pigment pastes and liquid colourants are essential tools for adding unique colour effects to resin projects. If you work with both UV and epoxy resin, you might wonder about their compatibility and the results you can expect. Here’s what you should know before getting creative.
Compatibility with UV and Epoxy Resin
Many modern pigment pastes and liquids, such as the Colourfun colourants, are suitable for both UV and epoxy resin. This cross-compatibility means you can achieve consistent results—vivid, even colours—whether you are making fast-setting UV jewellery or larger-scale art pours with traditional resin.
Pigment pastes offer high concentration for deep, opaque effects, while liquid colourants are generally more fluid and blend easily for translucent finishes. When choosing between the two, consider the look you want and the type of resin you’re using. Always add pigments gradually, mixing thoroughly to avoid streaks and ensure a smooth finish.
Mixing Tips for Best Results
For UV resin, use only a small amount of pigment to maintain clarity and ensure proper curing since excessive colour can sometimes inhibit the process. With epoxy resin, both pastes and liquids blend well due to the longer working time, allowing layered or gradient effects.
- Start with just a few drops or a small amount of paste.
- Mix thoroughly to achieve uniformity.
- Test on a small sample if you are unsure about pigment strength or compatibility.
When this matters
Choosing the right pigment type is especially important when your project requires a specific level of opacity, or when working with quick-setting UV resin where pigment load directly impacts performance. For statement jewellery or pieces requiring vibrant, solid colouring, pastes are ideal. For delicate washes of colour or glass-like effects, look for transparent liquid colourants such as the Magic Crystal range.
