Packaging and Transport

Like many industrial processed powdery materials, cellulose ether dusts are combustible and can cause dust explosions. Dust formation must be avoided or kept to a minimum. Care should be taken to prevent ignition from heat, spark, open flames or hot surface. BERMOCOLL CCA 312 is packed in in a polyethylene bag. Net weight 20 kg. We recommend emptying the bags from the bottom. The empty bags can be recycled or burned.

Storage & Handling

Storage Conditions
  • Bermocoll® CCA 312 should be admixed to the plaster in dry form before the water is added. Due to its small particle size Bermocoll® CCA 312 will dissolve rapidly after addition of water to the dry mix. At the temperatures above 250 °C (480 °F), charring of Bermocoll® CCA 312 will occur. At high temperatures and in contact with an open flame, Bermocoll® CCA 312 will burn slowly with the characteristics of cellulose.
  • In unopened bags, BERMOCOLL CCA 312 can be stored for several years. In opened bags, the moisture content of BERMOCOLL CCA 312 will be influenced by the air humidity.At the temperatures above 250°C (480°F), charring of BERMOCOLL CCA 312 will occur. At high temperatures and in contact with an open flame, BERMOCOLL CCA 312 will burn slowly with the characteristics of cellulose.
