Beschreibung
Zusammenfassung:	The present invention relates to a new formaldehyde-free binder composition for mineral wool products, wherein the binder composition is an aqueous composition containing starch, wherein an amount of 95 weight % or more of the starch is water-insoluble native starch, and an acrylic component. The present invention also relates to the use of this formaldehyde-free binder composition in the manufacturing of mineral wool insulation products. Finally, the present invention relates to a process for manufacturing the formaldehyde-free binder composition wherein a dispersion of starch, wherein an amount of 95 weight % or more of the starch is water-insoluble native starch, is brought in contact with the acrylic component at a temperature of not higher than 40° C.
