Can Silicone Putty Be Used With Resin?

Why Use Silicone Putty with Resin?

Silicone putty is a popular option for mould-making because of its flexibility, fast setting time, and ability to capture fine detail. It readily releases cured resin, making demoulding straightforward and hassle-free. Most importantly, high-quality putties—like the I–Gum Non-Toxic Silicone Putty—are formulated to be compatible with epoxy, polyester, and polyurethane resins, as well as wax and cement.

How to Use Silicone Putty for Resin Moulds

• Preparation: Mix the silicone putty’s two components in equal parts, following the instructions provided with your chosen product.
• Application: Press the mixed putty directly over the item you wish to replicate, ensuring even coverage and detail capture.
• Setting: Silicone putties typically cure within 20–40 minutes, after which the mould is ready for use with resin.

This rapid process makes putty especially convenient for quick, small projects and custom-shaped moulds.

When Silicone Putty Is the Ideal Choice

Silicone putty is best suited for one-off or small batch projects, jewellery, and instances where you need a fast turnaround. Its non-toxic formulation (like the I–Gum putty) allows for safer handling and easy use, even without gloves.
