Abstract
The invention concerns a method for making a binder, especially for mineral wool products comprising the steps of dissolving a particulate mineral material having a glassy amnorphous structure in an aqueous solution, nucleating and stabilizing the so obtained solution to form a sol having the desired particle size, and optionally adjusting the dry matter content of the sol. The invention also concerns a method for the production of a mineral wool product using the said binder for binding the fibers.
