Directions for Use & Precautions

  • Use the standard mass ratio 100:60 (856A:856B); adjust between 100:50-70 according to humidity and structure.
  • For CPP structures, increase curing temperature and glue amount as recommended.
  • Set seasonal temperature parameters (35-42C) for glue containers, hoses and rollers.
  • Maintain precise tension control and proper winding to prevent delamination and film curl.
  • Cure aluminum foil composites at 45-50C for 36-48 h; winter AL/CPP needs 48-60 h.
  • Clean the coating unit when the machine stops over 40 minutes.
  • Preheat 856B in the drying room if small lumps appear in cold winter; it does not affect use.
