Safety & Health

Safety Information
  • Handle the material with care. Avoid contact with water and moisture.
  • Reaction with water always results formation of Carbon dioxide and therefore increase of pressure in the closed storage container.
  • Avoid contact with skin and eyes. Do not inhale the vapors of the product.

Storage & Handling

Storage Conditions
  • ONGRONAT® 3600 preserves its quality stored between 25 and 50°C under a nitrogen blanket (dew point: - 40°C) for 6 months from the date of production.
  • During storage below 25 °C the quality of ONGRONAT® 3600 may deteriorate.
  • Product must not be stored above 50°C because its color can change and unwanted dimerisation may occur which leads to the decrease of the NCO content.
  • The product must not come into contact with water. In order to prevent water (moisture) ingress, nitrogen is used usually (dew point of -40 °C) to displace the air from the drums or containers.
  • It is not advised to use dry air as an inert blanket for the above purpose because due to contact with air or oxygen the color of the product may change to yellow due to the oxidation.
  • Since carbon dioxide (CO₂) is soluble in isocyanates, it is not recommended to be used as an inert gas either.
