AD-PAK 4200

AD-PAK 4200 is a high- performance, PFAS-free water repellent engineered to create a clear, high water contact angle, and non-greasy barrier on paper substrates. Its mild cationic nature enhances adhesion to fibers, while its durable film formation repels water and moisture without affecting printability or flexibility. Built with plant-based renewable content, it protects sensitive paper products from moisture degradation, while remaining fully recyclable and repulpable, making it ideal for carbonless paper systems and specialty labeling.

KEY BENEFITS

  • Excellent water resistance
  • 100% recyclable & repulpable
  • Heat-sealable barrier protection
  • Dries clear without greasy residue
  • Mixable with starches (up to 90% by weight)
  • Maintains flexibility & foldability
