Castable Wax Resin is a 20% wax-filled material engineered for casting applications. It captures intricate details, delivers smooth surface finishes, and ensures accurate castings with zero ash content and clean burnout. This makes it ideal for ultrafine jewelry structures and highly precise patterns used in casting and pressing dental prosthetics.

For jewelry, Castable Wax Resin provides high strength and stiffness, enabling the production of delicate features such as wire filigree. Its excellent green strength ensures reliable shape retention in thin and detailed patterns. For heavier jewelry, we recommend using Castable Wax 40 Resin.

IMPORTANT: 5 L Container Requires a Resin Pump to work.
