Nonwoven Binders
Nonwoven binder systems can use compatible melamine crosslinkers to improve wet strength, dimensional stability and durability, with selection based on polymer functionality, pH, catalyst and cure profile.
YDN385 is a current candidate platformYDN8080A may be evaluated in selected systemsBinder compatibility must be validated
Nonwoven binder systems use crosslinking to improve wet strength, dimensional stability and durability while retaining the required flexibility and hand.

CROSSLINKER STRATEGY
Choose chemistry around the process—not around a product code.
Resin chemistry direction
Water-soluble YDN385 is the principal current crosslinker direction; YDN8080A may be evaluated in selected systems.
Candidate YDNRESIN grades
- YDN385 — water-soluble high-imino platform
- Selected YDN8080A systems
PROCESS WINDOW
What formulators should verify
Crosslinker performance is determined by the full formulation and processing conditions.
BinderAcrylic, SBR, EVA, PU or other compatible dispersion.
PickupControls stiffness and binder add-on.
CureMust activate crosslinking without over-brittleness.
