Applications
DXB-3465D is currently used as a blocked polyisocyanate crosslinker raw material in the following application areas:
Final suitability should be evaluated in the customer’s actual formulation, substrate, process and curing conditions.
When to Consider DXB-3465D
Consider DXB-3465D when a formulation requires a solvent-based blocked IPDI trimer crosslinker and its confirmed 130–140 °C deblocking range is compatible with the planned application and curing process.
Application Fit
Current application directions include automotive coatings, electrophoretic coatings, flexible packaging adhesives, textile printing inks and metal coil coatings.
Selection Check
Refer to the Technical Data tab for the confirmed product specifications. Final grade selection should consider formulation chemistry, substrate, processing conditions and the required curing profile.
Contact Dongsen for grade-selection support when comparing blocked polyisocyanate options for a specific formulation or process.
