Хранение
  • Akrilan 420 has a shelf life of 6 months from delivery date if stored at temperatures between 5°C and 40°C in tightly closed original containers. As other dispersions, Akrilan 420 is sensitive to presence of Fe, Cu, Zn, Al. Avoid contacting these metals or their alloys. This applies not only to storage tanks, but also to pipelines, mixers, production tanks, etc.
