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: A molding process (100) comprising the step of inserting an uncured blank (102) in a mold cavity (14) formed in a mold system, the uncured blank including fiber and uncured binder, transferring heat from the mold system to a cool pressurized gas (108) to establish a hot pressurized gas, injecting the hot pressurized gas into the mold cavity (110), and transferring heat (112) from the hot pressurized gas to the uncured blank to cause the uncured binder to cure and establish a cured product (114).

Abstract: The invention described herein pertains to formaldehyde free, thermosetting liquid high solids binder compositions having rapid cure times on thermal curing and slow cure times at ambient temperatures so that the uncured binder compositions and products which comprise the uncured binder compositions have improved shelf lives.

Abstract: Binders to produce or promote cohesion in non-assembled or loosely assembled matter.
