Consultants’ Comments

  • “Seat impression tray when material begins to change to white color.”
  • “Liquid measure should be larger for two scoops of powder.”
  • “Improve instructions.”


Kromopan 100 is a stable alginate hydrocolloid with a chromatic phase indicator. The initial purple color indicates spatulation time; the pink color is tray loading time, followed by seating. The manufacturer claims that impressions can be stored for an indefinite period (100 hours) before pouring. Nineteen consultants used Kromopan 100 in more than 400 impressions. This product received a 95% clinical rating.

Product Features

Kromopan 100 received high ratings for ease of mixing, lack of dust, odor, and consistency. The color change is a very useful indicator of the working and setting time, thereby reducing the length of time the impression is in the mouth. The thick consistency and short setting time make the procedure very comfortable for patients, particularly those with a strong gag reflex. The resulting impression shows good detail, is smooth, and has minimal voids. Eighty percent of consultants indicated they would purchase and recommend Kromopan 100.Editors’ Note: The original evaluation was published in THE DENTAL ADVISOR Plus, Vol. 6, No. 1, January/February 1996.
