A striking opaque or solid resin effect can truly set your project apart, delivering deep, vibrant colour with no transparency. The key is using the right proportion of quality colourants, blended carefully to achieve flawless coverage.
Choosing and Mixing Your Colourant
For a reliably opaque finish, it’s important to select highly concentrated pigments or colour pastes designed specifically for epoxy or UV resin. Colourfun Liquid Epoxy Resin Colourant is formulated to give rich, dense colour with a small amount. Usually, achieving a solid result requires using up to 5% colourant by weight of mixed resin. Exceeding this can affect curing, so always measure carefully and blend thoroughly to avoid streaks.
Step-by-Step Guide for Solid Colour Effects
- Determine how much resin you’ll be using and calculate 3–5% of its total mixed weight for your colourant amount.
- Start by adding colourant gradually, thoroughly mixing with each addition.
- Check the mixture against a light source; if no light passes through, your resin is effectively opaque.
- Experiment first with a small, test batch to confirm opacity before proceeding with your full project.
When Opaque Effects Matter
Solid, opaque resin is ideal for projects where you want to hide inclusions or the base beneath—think statement jewellery pieces, artistic castings, or decor with bold hues. It’s also useful when sharp, well-defined colour coverage is needed, such as for resin inlays or patterns.
