PolyDADMAC contains strong cationic group radicals and activated-adsorbent group radicals. It can destabilize and flocculate the suspended solids and the negative-charged water-soluble matters in the wastewater through electro-neutralization and bridging adsorption. It is very effective in flocculating, decoloring, killing algae, and removing organics.
PDADMAC enjoys a small dosage but can cause big flocs, rapid precipitation, and low turbidity residue. On the other hand, PDADMAC overcomes the shortcomings of inorganic flocculants, such as loose floc structure, high flotation and low density, high water content, and poor sedimentation caused by hydrolysis.
Poly dimethyl diallyl ammonium chloride is adaptable to a wide range of pH values, between 0.5~1.4. PDADMAC is odorless, tasteless, and harmless.

When used alone, PDADMAC should be diluted to the concentration of 0.05%~0.5% (based on solid content). However, when PDDA is used to treat different sources of water or wastewater, the dosage is based on turbidity and water concentration.
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. Therefore, it is better to dose the product continuously.
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.
PolyDADMAC can be used in papermaking, coating, antistatic agent, AKD sizing promoter, and retention and drainage agent. PolyDADMAC is mainly used as standard titrant, anion-trapping agent, and retention aid in the paper industry.
PDMDAAC is applied to the coating of inkjet printing paper to improve the print quality and color firmness of the printed paper sheet and enhance the water resistance of the printed paper sheet, thus improving the premium feel of the inkjet printing paper.
PolyDADMAC also be used in decoloring and flocculation in water treatment (drinking and wastewater). PDMDAAC can be used not only as a flocculant but also as a bactericide. PDADMAC has a significant inhibitory effect on the growth of E. coli when the dosage is greater than 20mg/L.
PolyDADMAC can be used in daily chemicals as a shampoo carding agent, wetting agent, and antistatic agent.
PolyDADMAC can be used as a clay stabilizer, acid fracturing cationic additive, mud treatment agent, oily wastewater treatment agent, scale inhibitor, acidizing fluid additive, and plugging fluid in oilfield chemicals.
Packed in 200kg plastic drum or 1000kg/IBC drum or according to client order.
PolyDADMAC should be sealed and stored in a dry and cool place. This way, poly dimethyl diallyl ammonium chloride can be stored for two years without losing its effect. If stratification appears after the long-term storage, PolyDADMAC can be mixed before use.
