  • Can be diluted with esters, ketones, benzene solvents. Only urethane-grade (water content less than0.05%) solvents should be used to lessen the possibility of reacting with water. If diluted to a polyisocyanate fraction of less than 40%, turbidity, flocculation, and/or sedimentation may occur during storage. Storage trials should always be conducted.
  • Extremely sensitive to air humidity. When opening or in small packages, please prevent moisture from entering, seal it immediately after use or use it as soon as possible.
  • It must be kept in a cool and dry place and no outdoors. The shelf life is 9 months in the sealed package (from the date of delivery).
