ABSTRACT:
The invention relates to a process for the preparation of a gel material which is not free-flowing, is reversibly transparent as a function of temperature and comprises nonionic and/or nonionically acting surfactants as clouding components. The preparation of the gel material can be integrated into the customary production process for laminated glazing in a simple manner and produces frost-stable glazing which can be employed universally indoors and outdoors. When applied, the strength of the system is so high that it is no longer free-flowing at all and bulging of the laminated pane and running-out are therefore no longer possible.
