DADMAC is mainly used to produce polymers, to synthesize all kinds of macomolecular water treating agents whose functions are neutralization, absorption, flocculation, purification and decoloring, showing excellent effect in decoloring, killing algae and removing organic compounds in wastewater treatment, paper making and textile printing&dyeing industry. DADMAC is also used as modifier of synthetic resin to bring products electrical conductivity and antistatic property. DADMAC is often used as additive in daily chemicals to improve and modify product performances. As to petroleum chemicals, DADMAC can be used as flocculant and blocking agent.

Package and Storage:

DADMAC should be packed 200kg/plastic drum or 1000kg/IBC drum.

DADMAC can be stored in cool (4-30ºC) to avoid frozen and heat. We certify that DADMAC in correct storage will meet sales specifications for 12 months from the date of manufacture.
