Traxtone is a diestone dental stone material that produces highly-detailed impressions with minimum setting time. Casting material is pre-measured in special .0.9kg (2 lb) mixing bags. Simply add water and begin mixing. Special pigment flakes embedded inside the casting material indicate when the Traxtone is sufficiently mixed. Once all the pigment flakes have been blended into the mixture, it is ready to pour. Setting time is approximately 20-30 minutes. Because each bag is self-contained, Traxtone is easy to store and transport. There is no need to repackage bulk material and no need to worry about moisture. Traxtone provides superior detail reproduction and durability and has a higher compression strength than most casting materials at 18,000 psi. Kit items not included.
