FIELD: chemistry.
SUBSTANCE: invention relates to an aqueous sizing composition for mineral wool based insulation products. Composition comprises: (a) at least one carbohydrate selected from hydrogenated sugars, reducing sugars, and mixtures thereof, (b) at least one polybasic carboxylic acid or salt, or an anhydride of such an acid, (c) from 1 to 25 wt. %, relative to the sum of components (a) and (b), at least one aliphatic, cycloaliphatic or aromatic monohydric alcohol, free from acidic or basic functional groups and having an octanol / water partition coefficient (log Kow) in the range of 1–3.
EFFECT: improved mechanical properties of insulating products.
