Metallic and pearl finishes offer a stylish, eye-catching touch to resin castings. With the right pigments and techniques, you can produce professional-looking shimmer and lustre in your polyurethane resin work.
Choosing the Right Pigments
To achieve metallic or pearlescent effects, interference pigments and mica powders are the go-to solution. These finely milled powders are designed to disperse evenly throughout resin, providing iridescent sheens or deep metallic tones. Try options such as the “Sahara Space” Interference Metallic Pigment, available in multiple shades, for substantial colour impact with a little product.
Simple Application Tips
- Start by mixing your polyurethane resin components according to manufacturer instructions.
- Gradually add a small amount of pigment—no more than 5% of the total resin mass for best results.
- Stir gently but thoroughly to avoid air bubbles and ensure even dispersion. Overmixing is not needed—gentle, steady mixing gives a consistent finish.
- Pour as usual into your chosen moulds. Metallic effects will intensify as the resin cures, delivering a strong shimmer or pearly look.
When This Matters
If you want a result that stands out for decorative details, jewellery, prototypes, or art, these pigments transform plain resin into something extraordinary. They’re perfect for projects that demand a creative edge, whether for special gifts or standout craft items.
