Abstract: The present invention relates to an aqueous binding composition containing at least one reducing sugar; at least one sulphamate and/or sulphamic acid; a pH-adjusting agent which includes ammonium hydroxide (NH4OH), an organic and/or inorganic ammonium salt and/or an organic amine or combinations thereof; and at least one lactam. The binder may be effectively used to bind cotton fibers, cellulose fibers, organic fabrics, carbon powders, natural and artificial inorganic fibers, thus obtaining products with high mechanical properties.

Abstract: A method of manufacturing a mineral fibre thermal insulation product comprises the sequential steps of:



Forming mineral fibres from a molten mineral mixture;
Spraying a substantially formaldehyde free binder solution on to the mineral fibres, the binder solution comprising: a reducing sugar, an acid precursor derivable from an inorganic salt and a source of nitrogen;
Collecting the mineral fibres to which the binder solution has been applied to form a batt of mineral fibres; and
Curing the batt comprising the mineral fibres and the binder which is in contact with the mineral fibres by passing the batt through a curing oven so as to provide a batt of mineral fibres held together by a substantially water insoluble cured binder.
