Wax - 90% Paraffin wax:
Infiltration with wax predominately utilized when the models intended use is for casting, this will ensure clean burn-out. The model will be dipped into the hot wax infiltrating the model by 3 mm. Model remains fragile, as the wax adds no strength to the model. Note:
Model can not be painted after infiltration with wax.
Epoxy Resin:
Used to seal and give the model strength. The model is quite rigid. Can be sanded smooth and painted for presentation models.
Polyurethane - Rubber effect:
Model infiltrated with Polyurethane will have flexibility, depending upon geometry, working best with thin wall models.
