Application

N/A HD-3820 may be used alone or in combination with other polyurethane dispersion resins or additives. It may be applied by rotogravure, wire wound rod and spray.

Curing

N/A HD-3820 can be air-dried. Typical drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties. HD-3820 may be crosslinked with carbodiimides, water-dispersible isocyanates or polyaziridines to further enhance performance properties.
