Reliable Working Dies in Just Minutes!
For top-quality working dies, Mach-2 as a die silicone impression material is the perfect choice when it comes to indirect composite inlays, chairside denture repairs, resin veneers, temporaries, and silicone models for thermoformed trays such as orthodontic aligners and bleaching trays.
This die silicone impression material flows beautifully—better than stone—to create a smoother die and to capture minute detail. No hand-mixing—inject it directly from the automix cartridge into the impression. In addition, it sets exceptionally hard (90+ Durometer), yet remains slightly flexible, so composite inlays release easily. Set time: 2 minutes.
How to create a Mach model using Die Silicone Impression Material
Creating a Mach die is easy. Using a conventional impression gun, you simply inject the material directly from the automix cartridge into an alginate or reversible hydrocolloid impression. No mixing needed! Furthermore, Mach is highly fluid, so it flows much better than stone and creates a durable, smooth surface to capture exceptional detail.
As soon as you’ve poured the dies, create a model base using Super-Fast Blu-Mousse®. Two minutes later, you’re ready to remove the finished model and separate the dies. That’s it! Once it sets, this non-viscous die silicone impression material is extremely durable, so it won’t chip, abrade or crack—but it’s still flexible enough so composite inlays release easily. Simply trim the die using a common razor blade or Bard-Parker®. No burs! No dust!
Mach sets to an opaque, highly reflective color, so when you direct your curing light at an inlay’s occlusal surface, the transmitted light bounces off the prep walls and floor to promote polymerization from all directions. Prefer heat tempering? Just place the composite restorations into a toaster oven at 250°.
Practical Tips for Working with Die Silicone Impression Material
When making a model at room temperature, you are continually squeezing the gun to dispense the Mach into the impression. As you dispense, it immediately flows into the impression in the location where you have the dispensing tip positioned. As you continue to move the tip around the arch, newly mixed Mach is dispensed. Therefore, with each squeeze, the work time clock restarts for the newly dispensed material.
To fill a full upper arch impression could easily take a minute or more, but because you are continually dispensing newly mixed material, the work time for the material that was dispensed during the initial squeeze in reality becomes irrelevant.
Blu-Mousse is then added once the tooth part of the impression is filled with Mach.
