Directions for Use & Precautions

  • Set NCO/OH glue cylinder, hose and roller temperatures at 38-45C per the TDS typical parameters.
  • Control production environment temperature at 20-30C and humidity at 45-65%.
  • When humidity exceeds 70%, reduce 836B dosage by 5-10% and consult technicians for verification.
  • When humidity exceeds 90%, reduce humidity before use and ensure tight sealing during use.
  • For thin inner layer PE (<=45um), lower curing temperature to 30-35C and extend curing time to 24-36 h.
  • Replace the solvent-free mixing hose every day to avoid uneven mixing.
  • Wrap printed roll film with waterproof film after quality inspection to prevent moisture and dust.
