Powder pigments open up a world of vibrant colour for epoxy resin projects, from jewellery and casting to art and decoration. Achieving the best results involves a careful approach to mixing and dosage.
Mixing Powder Pigments Correctly
To avoid clumping and uneven colour distribution, always stir powder pigments thoroughly into component A (the resin) before adding the hardener. This helps achieve smooth results and minimises trapped pigment clusters that could potentially affect the resin’s cure.
- Use a small amount of pigment and test your colour intensity before committing to the full batch.
- If working with products such as “Neon” Bright Powder Pigments, aim for gradual build-up of colour rather than all at once.
How Pigment Dosage Affects Resin Properties
In most cases, powder pigments will not disrupt the curing process if you stay within recommended concentrations. Adding more than 15% pigment by weight may alter the mechanical properties or reduce the structural strength of your cured resin. For best results, keep pigment additions minimal and within manufacturer guidelines.
When the Details Matter
Paying attention to mixing technique and proportion is especially important for detailed casting, jewellery making, or when using rapid-cure resins, since high pigment load can increase the risk of imperfections or a less reliable set.
