Model and Mould Making Pastes
Large size models and tools are made with extrudable PUR and epoxy pastes providing a workable surface applied onto a stable core substructure. This technique is widely used to make plugs for boats or wind blades as well as automotive or architectural designs. This technology is beneficial versus boards as offering lighter models with a smooth and seamless surface (joint-free unlike boards).
The epoxy range provides higher dimensional stability and heat resistance for models or direct tooling applications in composite parts making.
