PURETHANE™ A 4002
PURETHANE™ A 4002 is a waterborne polyurethane dispersion used as the adhesive component in two-part dry-bond laminating systems for flexible packaging films.
Designed for clean converting and clear finished laminates, PURETHANE™ A 4002 supports stable coefficient of friction without relying on external slip additives. It produces UV-stable bonds while helping reduce odor, applicator-cell plugging, and leveling issues. For frozen-food structures and other demanding uses that require greater heat, moisture, or chemical resistance, combine the adhesive with PURETHANE™ C-CAT 104. Typical full-cure conditions are 24 hours at 130°F (54°C) or 72 hours at 100°F (38°C).
