Zusammenfassung:A method for producing mineral wool products with low formaldehyde emissions, comprises: (a) preparing an aqueous solution comprising resorcinol or a derivative thereof; (b) transporting a phenol-formaldehyde resin or a phenol-formaldehyde-urea resin to a binder application station; (c) metering the aqueous solution continuously to said resin while it is transported to the binder application station, thereby forming a binder solution; (d) applying the binder solution to mineral fibers; and (e) curing the binder solution by applying heat, thereby forming the mineral wool product.
