01Adhesion to metal substrates
01Consistent industrial bake response
CROSSLINKER STRATEGY
Choose chemistry around the process—not around a product code.
Resin chemistry direction
Highly alkylated and selected high-imino melamine crosslinkers can be evaluated according to binder chemistry and bake profile.
Candidate YDNRESIN grades
- YDN5130 — highly alkylated industrial direction
- YDN5158 — appliance / industrial direction
- Selected YDN525 / YDN535
PROCESS WINDOW
What formulators should verify
Crosslinker performance is determined by the full formulation and processing conditions.
Metal substratePretreatment and primer influence adhesion.
BinderPolyester / acrylic / alkyd system.
CureOven profile and line speed.
End useStain, cleaner and durability requirements.
