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.

Abstract: A polymerizable fluorine-containing composition is proposed, containing at least one polymerizable compound and at least one fluorine-containing compound, which for reducing the content of fluoride ions extractable with water of cured polymer masses obtainable from the composition additionally contains at least one magnesium compound. The composition is particularly suitable for bonding, potting and coating of electronic devices and for mounting electronic devices on printed circuit boards. Further proposed is a process for the preparation of cured polymer masses having a reduced content of fluoride ions extractable with water, comprising polymerizing and curing the composition to which at least one magnesium compound is added prior to the polymerization.
