Baldudak Hard Pottery Plaster (R23530)

Baldudak Hard Pottery Plaster

Baldudak Hard Pottery Plaster is specially developed for applications requiring high mechanical strength. It is particularly suitable for porcelain turning molds used in cup production and deep-structured forms.

Thanks to its dense and rigid molecular structure, it provides balanced wear across different regions of the mold. Controlled expansion properties eliminate expansion-related issues, ensuring dimensional stability and long service life.
