Facebook← Back to How do you catalyse cast synthetic resin?
Many creative makers want to enhance their resin castings with colourants or glitter, but it’s crucial to ensure the additives you use are suitable for your chosen resin. Here’s how to add vibrant or sparkling effects safely during catalysis for beautiful, reliable results.
Understanding Compatibility with Resin
Not all pigments, dyes, or glitters mix well with every type of synthetic resin. For best results, choose only colourants or additives that are labelled as compatible with your specific resin—whether it is epoxy, UV-cured, or another type. Using non-approved materials can affect curing, lead to cloudy finishes, or prevent full hardening.
Products like “UV–Creation” UV resin are specifically designed to accept a wide range of colourants, including those for darker or bolder colour effects. Always check product descriptions or consult the supplier if you are unsure.
How and When to Add Colourants or Glitter
The ideal point to introduce colourants or glitter is immediately after thoroughly mixing your resin and hardener, but before pouring into your mould or casting surface. This ensures even distribution and minimises bubbles. Stir slowly and gently for uniform colour without disturbing the curing process.
- Use small amounts at first – you can always add more, but too much may impair curing.
- For UV and fast-cure epoxies, quick mixing is essential as working time is limited once catalysis begins.
- Opt for fine glitters or well-dispersed pigments to avoid clumping.
When This Matters Most
Colourants and glitter are especially popular for resin jewellery, crafts, or table art where appearance is key. Using compatible additives helps achieve vibrant, lasting colour and ensures the finish remains clear and glossy. This is particularly important for projects requiring high clarity or unique effects, such as jewellery pendants or decorative coasters made using UV–cured resin.
