Overview
PURETHANE™ A 4002 is one component of a two-component waterborne laminating adhesive that creates clear, stable coefficient of friction laminations and clean machine performance. PURETHANE™ A 4002 forms UV‑stable bonds across flexible packaging. For higher‑performance needs such as frozen‑food structures or environments requiring added resistance, this grade is designed to be used with PURETHANE™ C‑CAT 104. Full cure typically develops after 24 hours at 130°F (54°C) or 72 hours at 100°F (38°C).
