Understanding Resin Sticking Issues

Epoxy resin art and casting can be immensely satisfying, but one common frustration is the resin sticking to your silicone moulds. While high-quality silicone should offer easy release, several factors—improper curing, worn moulds, or insufficient mould preparation—can lead to sticking or tearing. This guide explores the main causes of resin adhesion and offers expert solutions you can rely on for consistent, professional results every time.

Prevention is the key to smooth resin release

Prevention is the key to smooth resin release. Knowing the correct steps and using suitable products ensures minimal frustration and extends the life of your silicone moulds. Let’s cover the practical solutions and compare options from the ResinPro range to solve resin sticking, whether you are a beginner or a seasoned resin artist.

Comparison Overview: Which Solution Suits Your Project?

• Choose the right silicone mould: Pick moulds designed specifically for epoxy resin, like the “Silicone Hexagons Mould” – For Creating with Epoxy Resin – 24x21cm. Its professional-grade, non-stick silicone makes the demoulding process much easier.
• Try a specialist release agent: Applying Silicone Oil for Mould Protection and Easy Release – 15ml before pouring resin creates a protective barrier and protects your moulds’ flexibility.
• Opt for non-toxic mould making solutions: If you craft your own moulds, “I–Gum” – Non-Toxic Silicone Putty for Mould Making offers an odourless, glove-free mould making experience with integrated non-stick properties.

Why Resin Sticks to Silicone Moulds

Silicone moulds are a popular choice because they are flexible and, by nature, non-stick. However, resin sticking can occur if:

• The resin mixture remains uncured or sticky due to incorrect ratios or temperature issues.
• The mould surface is scratched, worn out, or retains residue from past projects.
• Poor quality silicone has been used, or the mould is not formulated to handle epoxy resin chemicals.

Using “Silicone Hexagons Mould” – For Creating with Epoxy Resin – 24x21cm can immediately improve results thanks to its flexibility, durability, and high resistance to deformation and heat. For those who enjoy custom shapes, “I–Gum” – Non-Toxic Silicone Putty for Mould Making ensures your self-made moulds retain non-stick performance and are safe and easy to use.

Practical Steps for Easy Demoulding

Follow these guidelines to demould your resin projects with minimal effort:

• Check for proper resin curing every time: Demould only when resin is fully hardened. If uncertain, let your project cure for additional hours to guarantee optimal results.
• Clean and care for your moulds: Remove any residual resin, dust, or oils gently to prevent micro-scratches and extend mould life.
• Consider a release agent such as Silicone Oil for Mould Protection and Easy Release – 15ml to create a barrier on the mould surface and keep it soft and flexible over time.
• For bespoke moulds, mixing “I–Gum” – Non-Toxic Silicone Putty for Mould Making in a 1:1 ratio, then shaping and letting it set, provides a stress-free demoulding experience for a range of cast materials.

Investing in high-quality, reusable options—like the “Silicone Hexagons Mould” – For Creating with Epoxy Resin – 24x21cm—ensures repeatable success for every project.
