Polymeric Quaternary Ammonium Salt Polydadmac for Paper Retention, Drainage and Dry Strength | Bluwat Chemicals
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.
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.
