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.

Embodiments of a curable formaldehyde-free resin, and a method for the manufacture of the curable formaldehyde-free resin are provided herein. The curable formaldehyde-free resin is provided in the form of an aqueous dispersion. The curable formalde-hyde-free resin comprises component a) a reducing sugar, component b) a polycarboxylic acid, component c) one or more polyols having a molecular weight of less than 1000 g/mol, and component d) epoxysilane. The total amount of component c) in the curable formaldehyde-free resin is between 0.5 and 10% wt. with respect to the sum of components a) and b). The amount of component d) is from 0.1% wt. to less than or equal to 2% wt. with respect to the sum of components a) and b). Further, a method for the manufacture of the curable formaldehyde-free resin according to one of the embodiments of the present disclosure is provided.

The present invention is directed to a mineral fibre product, comprising mineral fibres in contact with a binder resulting from the curing of an aqueous binder composition free of phenol and formaldehyde.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.
