DA402 High Solid Medium Viscosity PolyDADMAC Cationic Polymer Coagulant PDADMAC PDMDAAC for Water Treatment and Wastewater Clarification
PRODUCT INTRODUCTION
PolyDADMAC DA402 – High Solid Medium Viscosity Liquid Cationic Polymer
PolyDADMAC, also known as PDADMAC, PDMDAAC, PolyDMDAAC, Poly(dimethyldiallylammonium chloride), or Poly(diallyldimethylammonium chloride), is a high charge density cationic polymer widely used as a primary coagulant in water treatment and wastewater treatment systems.
DA402 belongs to the BLU DA Series high solid content grades and is designed as a medium viscosity concentrated liquid polymer. Compared with DA401, DA402 provides stronger floc formation while maintaining good pumpability and dosing stability. Compared with higher viscosity grades, it offers a more balanced combination of reaction speed, sedimentation performance, and operating convenience.
This grade is especially suitable for customers who need a concentrated PolyDADMAC solution with more floc strength than low viscosity products, while still keeping the product easy to handle in continuous dosing systems.
Bluwat Chemicals is a professional manufacturer of water treatment chemicals with more than 25 years of experience. We export to over 80 countries and support customers with product selection, jar testing, and application guidance based on real water samples.
According to the TDS, the BLU DA Series is widely used in drinking water treatment, wastewater treatment, textiles, mining, paper-making, oil industry, and sludge dewatering. It can be used alone or in combination with inorganic coagulants such as PAC, and it performs across a wide pH range.
For customers serving potable water projects, DA402 is positioned for drinking water treatment chemical applications under controlled dosing and proper process validation. Please verify current certification status separately if you plan to publish a direct NSF certification claim.

APPLICATIONS
PolyDADMAC DA402 is suitable for a wide range of treatment processes, including:
According to the TDS, the BLU DA Series is also used as a textile color fixing agent, in sugar processing, and in industries requiring strong cationic coagulation performance.
DOSAGE AND USAGE
For water treatment applications, DA402 can be used alone or blended into a treatment program with compatible inorganic coagulants such as Poly Aluminium Chloride (PAC). The TDS recommends dilution to 0.5%–5% based on solid content when used alone. Actual dosage should be determined according to raw water turbidity, contaminant profile, and jar testing results.
To achieve stable treatment performance:
- Dilute before dosing when required
- Optimize dosing point and mixing speed
- Ensure even dispersion in water
- Avoid excessive shear that may break flocs
