Poly (Dimethyl Diallyl Ammonium Chloride)(PolyDADMAC)
CAS No.: 26062-79-3
Molecular Formula: (C8H16ClN)n
Molecular Weight: 210000
Structural Formula:
Properties:
PolyDADMAC contains strong cationic group radicals and activated-adsorbent group radicals, which can destabilize and flocculate the suspended solids and the negative-charged water soluble matters in the wastewater
through electro-neutralization and bridging adsorption.
PolyDADMAC is very effective in flocculating, decoloring, killing algae, and removing organics. This textile auxiliary enjoys a small dosage but can cause big flocs, rapid precipitation, and low turbidity residue. PolyDADMAC is adaptable to a wide range of pH values, between 0.5~1.4. PolyDADMAC is odorless, tasteless, and harmless.

Application:
1. PolyDADMAC can be used in dyeing and finishing auxiliaries as an advanced formaldehyde-free color-fixing agent and can form a film in the fabric and improve color fastness.
2. PolyDADMAC can be used in papermaking, coating and antistatic agent, AKD sizing promoter, and retention and drainage agent.
3. PolyDADMAC also be used in decolor and flocculation in water treatment (drinking and wastewater).
4. In daily chemicals, PolyDADMAC can be used as a shampoo carding agent, wetting agent, and antistatic agent.
5. In the oil field chemicals, the PolyDADMAC can be used in clay stabilizers, acid fracturing cation additives, etc.
Usage：
PolyDADMAC should be diluted to the concentration of 0.5%-0.05% (based on solid content) when used alone. When PolyDADMAC is used to treat different sources of water or wastewater, the dosage is based on the turbidity and the
concentration of the water.
The most economical dosage is based on the trial. The dosing spot and the mixing velocity should be carefully decided to guarantee that the chemical can be mixed evenly with the other chemicals in the water and the flocs can not be broken. It is better to dose the product continuously.
Packing and storage:
Packaged in 200kg plastic drums or 1000kg/IBC drums or according to client order.
PolyDADMAC should be sealed and stored in a dry and cool place. In this way, PolyDADMAC can be stored for two years without losing its effect. If there appears stratification after the long-term storage, PolyDADMAC can be mixed before being used.
