Product Overview
Bluwat Poly(Dimethyl Diallyl Ammonium Chloride) Cationic Resin is a liquid PolyDADMAC polymer, also known as PDADMAC, Polydadmac or PolyDMDAAC. It is a water soluble cationic resin with strong positive charge density and is widely used in paper making, wastewater treatment, sludge dewatering and industrial water clarification.
In paper making systems, the wet end contains fibers, fines, fillers, starch, sizing agents, dyes, coating return, recycled fiber contaminants and dissolved anionic substances. These components can create unstable wet end chemistry, poor retention, high white water turbidity, slow drainage and higher chemical consumption.
Poly(Dimethyl Diallyl Ammonium Chloride) Cationic Resin helps control this problem by neutralizing negatively charged substances in the pulp slurry. It can improve the fixation of fines and fillers onto fibers, reduce solids loss into white water and support better drainage performance on the paper machine.
This product is suitable for paper mills that need better wet end charge balance, cleaner white water, improved retention and more stable paper production.

Why Paper Mills Use Cationic Resin
In modern paper making, recycled fiber and closed water circulation can bring more dissolved and colloidal substances into the wet end. These substances are often negatively charged and may interfere with retention aids, sizing agents and other papermaking chemicals.
When the wet end charge is not controlled, paper mills may face:
- Poor fines and filler retention
- High white water suspended solids
- Slow drainage on the wire section
- Unstable paper machine operation
- Lower efficiency of retention aid systems
- Higher chemical consumption
- Higher wastewater treatment load
Poly(Dimethyl Diallyl Ammonium Chloride) Cationic Resin provides strong positive charge. It helps neutralize anionic trash and improves the interaction between fibers, fines and fillers. This supports a cleaner and more stable wet end system.
Main Functions
Wet End Charge Control
The cationic resin helps neutralize negatively charged dissolved and colloidal substances in pulp slurry. This supports better wet end charge balance and improves the performance of other paper making additives.
Fines and Filler Retention
By improving charge interaction, the resin helps fines and fillers attach more easily to fibers. This can reduce solids loss into white water and improve retention efficiency.
Drainage Improvement
When fines and colloidal particles are better controlled, the pulp mat can drain more efficiently. This may support faster water removal and better paper machine runnability.
White Water Clarification
The product helps reduce suspended solids and turbidity in paper mill white water, supporting water reuse and reducing the load on wastewater treatment systems.
Sludge Dewatering Support
As a cationic polymer, it can also support sludge conditioning and dewatering in paper mill wastewater treatment processes.

Recommended Use in Paper Making
The best dosage and dosing point should be confirmed by laboratory testing and paper machine trial because paper furnish, recycled fiber ratio, filler type, pH, conductivity and wet end charge condition can vary between mills.
A typical evaluation process may include:
- Check pulp furnish, pH, conductivity and white water turbidity
- Analyze wet end charge condition and anionic trash level
- Dilute the cationic resin before dosing
- Add the resin into the selected wet end dosing point
- Mix evenly with pulp slurry for charge neutralization
- Test retention, drainage and white water clarity
- Adjust dosage according to machine performance
- Confirm results through paper machine trial
Suggested Dosing Points
The product can be tested at different positions depending on the paper machine system:
- Machine chest
- Blend chest
- Stuff box
- Fan pump inlet
- Short circulation system
- Before retention aid dosing point
- White water treatment system
- Save-all system
- Sludge conditioning system
The suitable dosing point should be selected according to mixing condition, reaction time, charge balance and production target.
Use with Other Paper Making Chemicals
Poly(Dimethyl Diallyl Ammonium Chloride) Cationic Resin can be used with other paper making and water treatment chemicals after compatibility testing.
It can support:
- Cationic PAM retention systems
- Anionic PAM retention systems
- Microparticle retention systems
- Starch and sizing systems
- White water clarification programs
- PAC or inorganic coagulants in water treatment
- Sludge dewatering chemical programs
The dosage sequence should be controlled carefully to avoid over-cationization or negative impact on other wet end additives.
Dilution and Dosage
When used alone for water treatment, the product is recommended to be diluted to 0.5–5% concentration based on solid content before dosing.
For paper making wet end applications, dilution and dosage should be adjusted according to pulp concentration, charge demand, retention target and paper machine operating condition.
Overdosing should be avoided because excessive cationic charge may disturb wet end balance, reduce the performance of other additives or cause deposits. The most economical dosage should be confirmed by retention test, drainage test, white water test and machine trial.
