Beschreibung
Zusammenfassung:	A method of manufacturing an insulation product is provided that includes collecting a plurality of inorganic fibers comprising at least 25 wt. % of bi- and tri-valent metal oxides on a substrate, applying a formaldehyde-free aqueous binder composition that includes a nitrogen-based protective agent to the collection of inorganic fibers, removing the nitrogen-based protective agent by heating the binder-coated inorganic fibers; and curing the aqueous binder composition via an esterification reaction.
