  • Publication number: 20070261986
    Abstract: A method for sterilizing medical single-component or multi-component impression materials that can harden, and a two-component impression material. In a first step of the method, the components of the impression materials that have not hardened are introduced into a primary packaging. In a second step, the primary packagings, with the components contained therein, are sterilized by heat sterilization. In a third step, the sterilized components in the primary packagings are introduced into a secondary packaging. In a fourth step, this secondary packaging is sterilized by means of a suitable gas sterilization, irradiation sterilization, and/or by means of sterilization in an autoclave, so that the activity and the viscosity of the components are not changed.
