Viscosity (25 °C, mPa.s): 2000-10000

Phenyl content (mol %): 2.5-20.0

Volatile content (150°C / 2h): ≤3.0

 

Applications:

  • Base material for manufacturing Extreme Low-Temperature RTV Sealants.
  • Formulating High-Temperature Resistant Potting Compounds (e.g., for aerospace).
  • Optical Bonding adhesives.

 

Package &Storage:

In 20kg pail, 200kg drum

Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. Keep in unopened containers, Shelf life is 60 months from the date of production. It is shipped as non-hazardous substance.

Storage beyond the shelf life does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
