With its smooth mixing characteristics and ample setting time, Excalibur produces a textbook model every time. Die trimming becomes a worry-free procedure due to the ultra-fine gypsum base, which prevents nicks and abrasions caused by brittleness. Recommended for use as crown and bridge or partial denture models. Suitable for use with all impression materials. Gypsum hardeners are not recommended. Indication for use: crown and bridge; porcelain; implants; cast partials; high-precision cases.
