Storage and Transport
When stored in closed containers, or in its original packaging in a dry place at room temperature, hecocell ®can be kept for a long time. In the case of high viscosity grades, a slow loss of viscosity can be measured after lengthy storage (>2year). hecocell® absorbs water from moist air. Once opened, container must be resealed and kept tightly closed.
Transport as moisture-proof ordinary chemicals.
