Mould release agents are used in composite manufacturing to prevent resins and finished components from bonding to mould surfaces. They create a protective barrier that allows cured composite parts to be removed without damaging the mould or finished product. Commonly used in fibreglass, carbon fibre and resin casting applications, mould release agents help improve surface finish, reduce production defects and support consistent results across repeated moulding cycles.

What are mould release agents used for in composite manufacturing?
What is the difference between silicone mould materials and mould release agents?
Silicone mould materials are used to create flexible moulds that reproduce detailed shapes, textures and complex geometries. Mould release agents, however, are applied to mould surfaces to prevent cast materials or composite resins from sticking during curing. Silicone mould materials are commonly used for resin casting, prototyping and component reproduction, while release agents support demoulding in composite manufacturing. The appropriate combination depends on the mould material, resin system and production process.
How do I choose the right mould release agent for epoxy, polyester or vinyl ester resin?
Choosing the right mould release agent depends on the resin chemistry, mould surface, curing temperature and production requirements. Epoxy, polyester and vinyl ester resins may require different release systems to achieve reliable demoulding without affecting surface quality. Wax-based, semi-permanent and specialist chemical release agents offer different application methods and performance characteristics. Ironbark Composites supplies composite chemicals in Australia, supporting manufacturers and fabricators in selecting suitable release products for their applications.
