PolyDADMAC can be used in dyeing and finishing auxiliaries as advanced formaldehyde-free color-fixing agent, and can form film in the fabric and improve color fastness.
PolyDADMAC is used for controlling disturbing substances in the papermaking process. It provides superior fixing of pitch from mechanical pulp and of latex from coated broke. Used in the short circulation of a paper mill to enhance retention and dewatering. In addition, it can be used to improve the efficiency of disk filters and flotators, and for cationization of fillers to provide maximal filler retention.
It is also used as a BOD COD reducer and as a color removal for high-color waste water from dyestuff industry.
PolyDADMAC are the most commonly used organic coagulants in water treatment.
Coagulants neutralise the negative electrical charge on particles, which destabilises the forces keeping colloids apart. In water treatment, coagulation occurs when a coagulant is added to water to “destabilize” colloidal suspensions.
This product (technically named Polydimethyl-Diallyl-Ammonium Chloride) is cationic polymer and it can be completely dissolved in water.
