Futar® D has an ultra rigid Shore-D hardness of 43. The material is thixotropic and will not run into the interproximal spaces, making it easier to remove. The material cures with a high-luster finish and has impressive permanent dimensional stability, virtually eliminating the risk of deformation and minimizing the possibility of changes during its shipment to the laboratory.
The final hardness enables the clinician or technician to grind it with an acrylic bur or cut it with a scalpel when modifications are needed. The working time for Futar D is 30 seconds with an intraoral setting time of 1 minute, 30 seconds.
