  • Patent number: 8987380
    Abstract: 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.
