20120289657 | FUNCTIONAL MATERIALS WITH CONTROLLABLE VISCOSITY - The present invention relates to an innovative method for controlling the viscosity of, for example, adhesives or coating formulations. The method for controlling viscosity allows very rapid thermoplastic curing of a formulation even at room temperature and a significant reduction in the viscosity at higher temperatures, thereby regaining the capacity for simple processing and allowing, for example, the originally bonded substrates to be separated from one another again with ease. A particular aspect in this context is that a plurality of cycles of thermoplastic curing and a significant reduction in the viscosity are possible with the present system. | 11-15-2012 |
20120309895 | FUNCTIONAL MATERIALS WITH REVERSIBLE CROSSLINKING - The present invention relates to an innovative method for the reversible crosslinking of, for example, adhesives or coating materials. The reversible crosslinking method allows very rapid crosslinking even at room temperature and undoing of the crosslinks at higher temperatures, thereby regaining the capacity for thermoplastic processing and allowing the originally bonded substrates to be separated from one another again with ease. A particular aspect in this context is that a plurality of cycles of crosslinking and undoing of the crosslinks are possible with the present system. | 12-06-2012 |
20130172480 | FUNCTIONAL MATERIALS HAVING A CONTROLLABLE VISCOSITY OR REVERSIBLE CROSSLINKING VIA AZA DIELS-ALDER REACTIONS WITH BISHYDRAZONES OR CONJUGATED BIS-SCHIFF BASES - The present invention relates to innovative materials which are reversibly crosslinkable by means of a thermoreversible mechanism and/or whose viscosity is reversibly adjustable.
