Abstract: A binder comprising the products of a carbohydrate reactant and polyamine is disclosed. The binder is useful for consolidating loosely assembled matter, such as fibers. Uncured fibrous products comprising fibers in contact with a carbohydrate reactant and a polyamine are also disclosed. The binder composition may be cured to yield a fibrous product comprising fibers bound by a cross-linked polymer. Further disclosed are methods for binding fibers with the carbohydrate reactant and polyamine based binder.

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.

Abstract: A method of using an amine compound including at least one amine functional group, wherein the amine functional group(s) comprise primary and/or secondary amine functional groups, to reduce the level of furfural and/or hydroxymethylfurfural in a carbohydrate-based binder or binder composition and/or escaping in the course of preparation, cross-linking and/or curing of carbohydrate-based binders, is provided. The carbohydrate-based binder is obtained from a carbohydrate-based binder composition comprising a carbohydrate component, a cross-linker and optionally one or more reaction products of the carbohydrate component and the cross-linker, wherein the cross-linker is selected from the group consisting of ammonium salts of inorganic acid, carboxylic acids, salts, ester and anhydride derivatives thereof, and combinations thereof.
