Application Information:

  1. Mixing Informations:
    Do not open containers untill ready to use. Stir Part B before use.
  2. Cleaning of Equipment:
    Equipment etc., may be cleaned with Methyl EthylKetone(MEK) or Methylene Dichloride immediately
    after use or before material cures. Use "RITE OFF" to remove any cured material
  3. Packing,Shipping, Storage & Handling:
    GC Encapsulation Compounds are moisture sensitive and have a storage life of 24 months when
    kept in their original unopened containers and stored at temperatures between 10-25°C in a dry area.
    Containers must be kept tightly closed when not in use
