CHARACTERISTICS

KROMOTYPO 4 is a type 4 CHROMATIC extra-hard stone with extra-fine granulometry specific for the preparation of total and partial non-removable MASTER models, stumps preparation, metal framework, implants and antagonist models.

After mixing water and powder, the compound color turns to yellow. When the color turns to pink it is time to cast the model. Finally, when the compound color turns back to yellow the model can be removed from the impression.

The extra-fine granulometry of KROMOTYPO 4 is a guarantee for obtaining accurate fine and homogeneous stone with high resistance to compression, abrasion, chippings free and resistant during the prothesis preparation.

KROMOTYPO 4 is compatible with all impression material and all products for the isolation of plaster against plaster.

Final color: pastel yellow

The working time can be adjusted with Time Out.
