When stored in closed containers, or in its original packaging in a dry place at room temperature, CELOPRO 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 (>1 year). CELOPRO absorbs water from moist air. Once opened, container must be resealed and kept tightly closed.
Packaging:
Packed in 25 kg multilayer paper sack with polyethylene intermediate layer and inner P.E. bag.
