Are Silicone Moulding Materials Safe and Non-Toxic?

← Back to How to make moulds for epoxy resin?

When making epoxy resin moulds, questions often arise regarding the safety and non-toxic properties of silicone materials. Today’s leading silicones for mould making are formulated to be user friendly and safe when used as intended.

Understanding Non-Toxic Silicone Moulding Materials

Selected silicones such as I–Gum and Pure Mould are classed as non-toxic, meaning there are no harmful emissions or irritants under normal use. I–Gum, in particular, allows for handling without gloves and is odour-free, making it suitable for both hobbyists and professionals working with epoxy resin. Always be sure to follow the product’s guidance for mixing and handling for optimal safety.

Safe Handling and Usage Guidance

Though non-toxic, sensible safety practices remain important. Work in a ventilated space and avoid unnecessary skin contact with uncured components. After mixing, the cured silicone becomes an inert, flexible mould that poses minimal health risk during regular use. For those seeking extra peace of mind, look for products which are specifically marked as solvent-free and certified non-toxic, like Pure Mould.

When This Matters

If you’re sensitive to strong odours or wish to avoid prolonged glove use, non-toxic putties like I–Gum are especially suitable.
