The invention relates to the use of a mixture of at least two reducing sugars to form the basis of a sugar-based uncured binder disposed on mineral fibers, in order to avoid a supersaturated aqueous solution of such binder crystallizes out while storing at ambient conditions over a time span of longer than 2 weeks, wherein the mixture of at least two reducing sugars has a lower crystallization point than dextrose, wherein the binder composition further comprises a crosslinker selected from ammonium sulphate, ammonium phosphate, ammonium nitrate, ammonium carbonate salts and combinations thereof and/or an ammonium salt of a polycarboxylic acid. |
