Technical Details & Test Data

Processing Guidelines

The Arathane® 5888 IS and Arathane® 5888 PO components are mixed according to the specific ratio at ambient temperature, preferably using automatic dosing and mixing equipment. If the Arathane® 5888 PO component has been stored for an extended time, it is recommended to stir well the complete content of the container. The fillers present in Arathane® 5888 IS and Arathane® 5888 PO have a tendency to separate during extended storage. This may be prevented by periodic slow agitation of the containers.

  • Mix ratio by weight (Arathane® 5888 IS / Arathane® 5888 PO) : 13 / 100
  • Mix ratio by volume (Arathane® 5888 IS / Arathane® 5888 PO) : 17.2 / 100
  • Initial mixed viscosity, 25°C, cps (mPas) : 4,000 – 5,000

Storage & Handling

Storage Information
  • Arathane® 5888 IS US (isocyanate component) should be stored in a dry place, in the sealed original container, at temperatures between 2°C and 18°C (36°F and 64°F).
  • Under these storage conditions the shelf life is 6 months from the date of manufacture. Tightly reseal container immediately after use.
  • Purging the partially used containers with dry nitrogen is strongly recommended because Arathane® 5888 IS US is very moisture sensitive.
  • The product should not be exposed to direct sunlight.
  • Arathane® 5888 PO US (polyol component) should be stored in a dry place, in the sealed original container, at temperatures between 2°C and 40°C (35.6°F and 104°F).
  • Under these storage conditions the shelf life is 6 months from the date of manufacture.
  • The product should not be exposed to direct sunlight.
