What resin should be used for moulds?
Selecting the right epoxy resin for every moulding and casting project
When creating unique designs with silicone moulds or producing striking resin art, selecting the right resin ensures clarity, durability, and ease of use. Whether you’re crafting jewellery, pouring river tables, making functional decor, or experimenting with creative castings, different types of epoxy resins deliver optimal results for specific moulding applications. Read on to discover which ResinPro products match your project needs.
Resin Selection Guide for Moulds: When Clarity, Depth, and Speed Matter
Selecting a resin for moulds comes down to three main factors: project thickness, required clarity, and demoulding speed. Here is a concise comparison overview of our best-suited options:
- “Icrystal” – Clear Epoxy Resin – Odourless Formula – Up to 1.5cm is ideal for shallow, transparent, odourless projects such as jewellery and surface coatings that require a crystal finish.
- “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm supports clear, detailed casting in layers up to 2cm for woodworking, art, and DIY projects.
- “EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects – Up to 5cm is designed for medium-depth casts ideal for river tables, thicker decor, and art projects between 2cm and 5cm.
- “Epoxytable 10-Ten” – Deep Pour Epoxy Resin for Tables, Up to 10cm Casting handles super-deep moulds, such as furniture and art up to 10cm thick with low risk of overheating.
- “One-2-One” – Epoxy Resin for Handcraft, 1:1 Mixing Ratio is perfectly suited for beginners and crafters who want a hassle-free experience with smaller, decorative moulds.
- “ICreation” – Fast Epoxy Resin, 6h Demoulding, Transparent Gloss Finish offers rapid demoulding for time-critical crafts and jewellery making.
Choosing Resin Depends on Mould Type and Application
Not all moulding projects require the same resin: the thickness and detail of your design influence the best product for you. Shallow moulds or jewellery benefit from odourless, easy-mix epoxies, while deep table pours demand resins with controlled reactions to prevent cracking or yellowing. Assess your project scope and select a resin with matching features for professional, reliable results every time.
Overview of Resin Properties for Different Moulding Needs
When choosing a resin, consider your project’s exact thickness and the level of detail or finish desired:
- Shallow Moulds (up to 1.5cm): “Icrystal” is odourless, easy to mix (2:1 ratio), and demoulds fast – great for jewellery or functional coatings on wood, decorations, and creative pieces where perfect clarity is crucial.
- General Casting (up to 2cm): “Trasparente” provides an ultra-clear formula, integrated UV filter, and high scratch resistance for decorative moulds, art, and furniture. It’s beginner-friendly and includes essential tools for hassle-free mixing.
- Medium-Depth Casting (up to 5cm): Use “EpoxyTable 5-Five” for deeper pours like river tables and larger art. Its low exothermic reaction minimises overheating, and it provides a scratchproof, heat-resistant finish.
- Deep Pour & Large Artistic Projects (up to 10cm): “Epoxytable 10-Ten” enables extra-thick castings for statement furniture, artistic centrepieces, and installations without yellowing or heat risks.
- Handcraft & Decorative Moulds: “One-2-One” is ideal for beginners, with its easy 1:1 mixing ratio, non-toxic formulation, and super-glossy finish, making it safe and simple for small items or encapsulation.
- Fast Cure for Tight Deadlines: “ICreation” accelerates your workflow with 6-hour demoulding time and 12-hour full cure. Perfect for high-turnaround jewellery and decorative moulds.
All recommended products include UV filters to minimise yellowing and improve durability over time.
How to Decide: Matching Resin Features to Your Project
Choosing between these resins isn’t just about thickness—think about your priorities, such as clarity, surface finish, ease of mixing, and project speed.
“Icrystal” and “One-2-One” are especially useful for those wanting fuss-free preparation, with easy mixing ratios and odourless or non-toxic formulas. For depth or clarity in furniture and larger objects, “EpoxyTable 5-Five” or “Epoxytable 10-Ten” avoid overheating and deliver longer working times. Fast jewellery makers and crafters benefit most from “ICreation” for its rapid turnaround and crystal-clear, self-levelling surface.
When in doubt, check against your mould’s maximum depth and target use: for highly decorative, small-scale moulds or encapsulations, easy-mix and rapid cure products shine. For ambitious furniture, thick resin art, or feature installations, opt for deep-pour specialist resins from the range.

Frequently Asked Questions
Which resin should be used for moulds up to 2cm thick?
Casting epoxy resins like “Trasparente” are suitable for moulds up to 2cm thick, providing clear and durable results for detailed projects.
What happens if I pour Trasparente resin thicker than 2cm?
Pouring above 2cm may cause overheating, resulting in heat build-up and possible surface or internal defects. For thicker layers, consider a deep pour resin.
