  • HDX-60HL is sensitive to moisture. Care should be taken to use or split charging to avoid the vapor. It must be sealed tight after use up as soon as possible.
  • HDX-60HL should be placed in a cool, dry indoor environment at room temperature (0-30°C), protected from direct sunlight and other chemical materials.
  • The shelf life is up to 6 months if it is stored in its sealed original drums.
  • Solvents containing reactive groups (e.g. water. alcohols, amines) should not be used since they react with the PU hardener. It is recommended to use “urethane grade” solvent for the dilution (with water content below 500 ppm) , and aim for a minimum of ≥25% solid content after dilution.
  • HDX-60HL is to use with our PU hardener together, recommended to use 5% to 50% according to the formula. This product should not be used as a standalone component.
