Abstract
The invention relates to preparations with improved curing behavior, which are characterized in that they contain 0.0005 to 50 wt. % of soluble and/or fine-particle organic and/or inorganic alkaline earth and/or alkali metal compounds. The preparations according to the invention may be used for bonding, sealing, casting and coating substrates, also in medical dental and technical dental preparations, and for making impressions of articles and, more particularly, for making dental impressions.
Claims13
A cationically polymerizable dental preparation based on monomers which are selected from the group consisting of N-alkylaziridine group-containing monomers and epoxy-containing monomers, wherein the preparation contains 0.0005 to 50 wt. %. of soluble and/or fine-particle organic and/or inorganic alkaline earth and/or alkali metal compounds in order to adjust the curing behavior and to improve the storage stability, wherein the preparation consists of a base component and, separately therefrom, a catalyst component, wherein the base component contains the monomer(s) and the catalyst component contains the species initiating polymerization, optionally in a diluent, and wherein the alkaline earth and/or alkali compounds are present in the base and/or catalyst component, and wherein the preparation further comprises a polymerization-initiating substance or a substance from which a polymerization-initiating substance is produced.
