Recommended Depth Limits for Epoxy Resin in Silicone Moulds

Q: Recommended Pour Thickness for Epoxy Resin

For most standard epoxy resins such as Trasparente , it's best to pour in layers up to 2cm thick. Keeping within this limit helps control heat generation during curing and produces a strong, ultra-clear finish in your silicone moulds. Thicker pours in a single layer can risk overheating, compromising the clarity or integrity of your cast.

Q: Practical Tips for Successful Casting

Layering for Depth: To create objects deeper than 2cm, pour the resin in multiple thin layers, allowing each one to partially set before adding the next. Ambient Temperature: Work in a cool, well-ventilated area to help prevent unwanted heat buildup. Choosing the Right Mould: High-quality silicone moulds, like the Silicone Hexagons Mould , pair well with epoxy resin and make demoulding straightforward.

When This Matters

Adhering to the recommended pour depth is particularly important for jewellery making, craft projects, and decorative objects where clarity and strength are crucial. Overpouring can lead to cloudy finishes or even damage the mould over time.
