Curious whether UV resin works in silicone moulds? Here’s a practical guide to get the best finish using UV resin, plus what to look out for before you start your next resin craft project.
Do UV Resin and Silicone Moulds Work Together?
UV resin is generally compatible with silicone moulds. The only essential requirement is that your mould should be translucent—this allows ultraviolet light to reach and fully cure the resin. Opaque moulds block UV rays, which means the resin will remain tacky or unset in areas that aren’t exposed to the lamp.
Tips for Successful UV Resin Casting
- Always check translucency: Choose a clear or semi-transparent silicone mould for best results. Products like “Pure Mould” Silicone Rubber are ideal, as their clarity supports even curing.
- Work in shallow layers: UV resin cures most efficiently in thin pours. If your project is deeper than a few millimetres, cure each layer separately under a UV lamp.
- Use the right equipment: A dedicated UV lamp is required to cure the resin. Check it covers your entire mould area for consistent results.
When This Matters Most
Using UV resin in silicone moulds is especially useful for small, intricate projects—like jewellery, charms, or festive ornaments—where a fast, clear finish is needed. Kits such as the UV Resin Kit with 5 Christmas Silicone Moulds combine the right materials to get started quickly.
