  • Adhesive systems
    Patent number: 6835271
    Abstract: The invention relates to the use of adhesive systems which are radically polymerizable and contain 1-30 wt.-% of a reactive solvent with a pKS value less than or equal to that of acetone and are used for the attachment of materials which are only or also cationically polymerizable to hard tissue containing water. The adhesive systems contain at least one component i) which is capable of starting a radical reaction and one component ii) which contains radically polymerizable monomers which are acid-functional or contain groups which can form acids and optionally customary additives.

  • Adhesive systems
    Patent number: 6767935
    Abstract: The invention relates to the utilization of an adhesive system containing at least one component i) which is capable of initiating cationic polymerization and is selected from unsaturated carbonic acids and their anhydrides or acid chlorides, unsaturated phosphoric acids and their esters, unsaturated phosphonic acids and their esters, unsaturated sulfonic acids and their esters, and strong inorganic acids, and at least one component, ii) that can undergo cationic polymerisation for the hardening of radical or cationic or radical and cationically curable materials on laminated fabric which contains water.
