Fiberglass nonwoven binder

摘要

Formaldehyde-free nonwoven mat formed from fibrous substances and a binder composition containing a copolymer having an acid and a hydroxyl, amide or amine functionality. The invention also relates to the use of polyamines as crosslinkers for a polymer binder. The binder composition is especially useful for binding mineral fiber, and particularly as a fiberglass binder. The binder composition provides a strong yet flexible bond that allows compressed fiberglass mats to easily expand once the compression is released.
