  • HDX175-MPX can be diluted with esters, ketones, glycolether acetates or with aromatic hydrocarbons. Only urethane-grade solvents should be used with water content below 500 ppm. Storage trials should always be conducted for applications.
  • Avoid using solvents that contain reactive groupsuch as water, alcohols, amines. These solvents can negatively interact with the HDI hardener and compromise its effectiveness.
  • HDX175-MPX should not be diluted to a solid content of less than 40%. It may experience turbidity or sedimentation during prolonged storage when diluted below this solid content.
  • After dilution, it is advised to have a solid content of at least 25% in the solution.

HDX-175MPX must be stored in a tightly sealed container to prevent exposure to moisture and air. The products should be placed in a cool, dry indoor environment at room temperature (15-25°C), protected from direct sunlight and other chemical materials.
