Wirobond® C 250 g

• Nickel- and beryllium-free

• Simple processing thanks to reliable casting time recognition

• Carbon-free composition – particularly well suited for laser welding

• The element cerium ensures high bond strength with the ceramic, minimising the risk of subsequent flaking or chipping

• Low thermal conductivity – protects the pulp and ensures high wearing comfort for the patient

• Biocompatible and corrosion-resistant thanks to a firmly-adhering passive layer
