Kromotypo 3

Kromotypo 3 is a type-3, color-changing, hard stone with extra-fine granulometry specific for the preparation of total and partial removable master models, metal framework, study, preliminary and antagonist models.

Color changing process:

• After mixing water and powder, the compound color turns to light-blue.
• When the color turns to purple it is time to cast the model.
• Finally, when the compound color turns back to light-blue the model can be removed from the impression.

The product’s excellent resistance to compression and abrasion favors the preparation of non-removable prosthesis. The extra-fine granulometry of Kromotypo 3 is a guarantee for obtaining accurate fine and homogeneous stone with high resistance to compression, abrasion, chipping. It remains resistant throughout the prothesis preparation.

Kromotypo 3 is compatible with all impression material and all products for the isolation of plaster against plaster. The working time can be adjusted with Time Out.
