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 binder comprising a polymeric binder comprising the products of a carbohydrate reactant and nucleophile is disclosed. The binder is useful for consolidating loosely assembled matter, such as fibers. Fibrous products comprising fibers in contact with a carbohydrate reactant and a nucleophile 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: The present application relates to wood boards, particularly post-cured wood boards and more particularly to particle board with excellent swelling properties; it also relates to a process for production of such boards.

Abstract: A method of manufacturing a mineral fiber thermal insulation product comprises the sequential steps of: Forming mineral fibers from a molten mineral mixture; spraying a substantially formaldehyde free binder solution on to the mineral fibers, the binder solution comprising: a reducing sugar, an acid precursor derivable from an inorganic salt and a source of nitrogen; Collecting the mineral fibers to which the binder solution has been applied to form a batt of mineral fibers; and Curing the batt comprising the mineral fibers and the binder which is in contact with the mineral fibers by passing the batt through a curing oven so as to provide a batt of mineral fibers held together by a substantially water insoluble cured binder.

Abstract: A curable aqueous composition is disclosed comprising a carbohydrate, a crosslinking agent, and an amine base, wherein the curable aqueous composition has a pH adjusted by the amine base. Further disclosed is a method of forming a curable aqueous solution.

Abstract: In a stack of composite wood boards, the wood boards comprise wood particles and an organic binder.

Abstract: A packaging machine (10) includes a machine foundation (22) and a variable-width belt system (24). The variable-width belt system (24) is moved relative to the packaging machine and configured to establish a belt pocket (26). A product is admitted into the belt pocket and rolled onto itself to establish a rolled product (16) as the belt moves relative to the machine foundation (22).

Abstract: A curable aqueous composition is disclosed comprising a carbohydrate, a crosslinking agent, and an amine base, wherein the curable aqueous composition has a pH adjusted by the amine base. Further disclosed is a method of forming a curable aqueous solution.

Abstract: A binder based predominantly on molasses which incorporates both polymeric and monomeric polycarboxylic acid components to form a composite including both melanoidin and polyester polymeric structures. The binder incorporates the chemical profile of molasses with a mixture of polycarboxylic acids which combines to form a strong and weatherable binder composition which may be used to bind loosely or non-assembled matter.

Abstract: Composite Maillard-resole binders to produce or promote cohesion in non-assembled or loosely assembled matter.

Abstract: A curable aqueous composition is disclosed comprising a carbohydrate, a crosslinking agent, and an amine base, wherein the curable aqueous composition has a pH adjusted by the amine base. Further disclosed is a method of forming a curable aqueous solution.
