About model and die hardeners
A model hardener is applied to the gypsum of a cast or die; in one laboratory study a die hardener significantly improved Type IV dental stone. What improved was the mechanical properties of the stone. That study compared cyanoacrylate, resin-based and colloidal silica-based hardeners.
These are the materials used on and around the cast and the die: duplicating materials, hardeners, die spacers, block-out materials, separating agents, adhesives and epoxy die materials. A die is the positive reproduction of the form of a prepared tooth.
How the materials on this shelf differ
- Duplicating & Die Silicone — A silicone that makes a flexible mould of the master model.
- Duplicating Materials & Flasks — Gels and silicones for copying a master model.
- Model Hardeners — Strengthens and hardens the surface of the stone.
- Die Spacers — Painted on the die to leave room for the cement.
- Blockout Materials — Fills undercuts and voids that the work must not enter.
- Die Lubricants & Separating Agents — A coating that keeps wax or another material from sticking to the die.
- Model Adhesives — A glue for model work.
- Epoxy Die Materials — A resin die material used in place of die stone.
What to look at when choosing
Hardener chemistry: in the study above the cyanoacrylate hardener gave the greatest improvement in surface hardness and compressive strength.
Duplicating material: the standard is written for materials that form flexible moulds of a properly blocked-out master model.
Pack: silicones are sold as base and activator, by weight; spacers, hardeners and lubricants by the bottle.
