Silicone Rubber Compatibility and Detailing

Compatible Casting Materials

Silicone rubber moulds from ResinPro are suitable for many popular casting mediums. These include epoxy, polyester and polyurethane resins, as well as acrylics. Additionally, you can safely use silicone moulds with soap bases, polymer pastes, natural and synthetic waxes, plaster, and cement. This broad compatibility makes liquid silicone rubber an excellent choice for artists, jewellery makers, makers of decorative objects, and prototype developers alike.

• Plaster and cement
• Wax (natural and synthetic)
• Soap and polymer pastes

Ensuring Fine Detail and Quality

One of the key strengths of liquid silicone rubber is its ability to capture intricate details, including fine lines and pronounced undercuts. For best results, prepare the original object and formwork carefully to minimise air bubbles. Silicone putties like I–Gum offer a convenient 1:1 mix, while liquid versions may require a catalyst. Using a pressure pot for curing can increase detail reproduction and mould life, especially for professional or high-volume projects.

When Compatibility Matters Most

Choosing a silicone rubber compatible with your casting medium is vital when moulding unique or delicate items, as incompatibility can cause incomplete cures or poor results. If you plan to work with a mixture of materials or need reusability, a product like Pure Mould offers versatility and easy observation of your work thanks to its translucency.
