Abstract
A sizing composition for insulating products based on mineral wool, in particular on rock or glass, the composition including at least one dextrin, at least one organic polycarboxylic acid having a molar mass of less than or equal to 1000, and a catalyst chosen from Lewis acids and bases, phosphorus-comprising compounds and compounds including fluorine and boron.

A sizing composition for insulating products based on mineral wool, the composition comprising:
- at least one dextrin,
- at least one organic polycarboxylic acid having a molar mass of less than 1000, and
- a catalyst chosen from phosphorus-comprising compounds and compounds comprising fluorine and boron.
A process for the manufacture of an acoustic and/or thermal insulating product based on mineral wool, the process comprising:
- projecting a sizing composition onto said wool;
- and
- treating said wool at a temperature permitting crosslinking of the sizing composition and formation of an infusible binder,
- wherein the sizing composition comprises:
- at least one dextrin,
- at least one organic polycarboxylic acid having a molar mass of less than 1000, and
- a catalyst chosen from phosphorus-comprising compounds and compounds comprising fluorine and boron.
