Polymeric Quaternary Ammonium Salt for Paper Retention, Drainage and Dry Strength
Bluwat Chemicals — PolyDADMAC solutions for modern papermaking
Overview
Bluwat Chemicals supplies PolyDADMAC, a polymeric quaternary ammonium salt also described as a cationic polyelectrolyte, for wet end optimization in paper mills. It serves as a cationic retention aid, a drainage improvement polymer, and a dry strength resin to stabilize wet end chemistry, improve machine runnability, and enhance sheet properties across printing and writing, packaging, and board grades.
Cationic retention aid Drainage improvement polymer Dry strength resin Wet end control
Key Benefits in Papermaking
- Retention — improves fines and filler capture, reduces losses to white water, and supports stable formation.
- Drainage — accelerates dewatering on wire and press to reduce thermal load in dryers.
- Dry strength — increases tensile and internal bond while maintaining optical properties.
- Compatible with starch, sizing systems, PAC, bentonite, and silica sols for dual or microparticle programs.
- Broad pH operability supports seasonal furnish shifts and closed loop water systems.

Papermaking Applications
- Cationic retention programs to improve fines and filler retention and stabilize white water loops.
- Drainage programs to increase dewatering rate and support higher machine speed.
- Dry strength enhancement for tensile, SCT, and internal bond on fine papers and board.
- Process water clarification to polish saveall overflow and short circulation water for reuse.
Dosage and Use
Liquid grade make up
Dilute to 0.5–5% and dose to machine chest, fan pump, or white
water line as required.
Powder grade make up
Prepare 0.5–10% solution and allow complete dissolution before
dosing.
Program design
Use alone or in dual and microparticle systems with starch, PAC,
bentonite, or silica sols.
Optimization
Confirm dosage with lab or machine trials and monitor drainage,
retention, ash profile, and strength indices.
