1. Product Introduction & Main Application
Arnico’s PolyDADMAC is a high charge density, liquid organic cationic polyelectrolyte, ranging from colorless to pale yellow. It acts as a powerful primary coagulant in water and wastewater treatment, rapidly neutralizing and destabilizing negatively charged colloidal particles without significantly altering the system’s pH, unlike traditional metal salts.

3. Features & Benefits
-
Stable Performance Across a Wide pH Range: Unlike metal-based coagulants (e.g., PAC), it operates effectively without performance loss in a broad pH range (4 to 9).
-
Reduced Sludge Production: Produces up to 70% less sludge volume compared to aluminum sulfate, drastically cutting disposal costs.
-
Fast & Effective Coagulation: Rapidly neutralizes particle charges, forming tight micro-flocs that enhance filtration and clarification.
-
High Compatibility: Excellent blendability with other coagulant aids and polyacrylamide flocculants to increase final floc size.
4. Industrial Applications
-
Drinking Water Treatment: A safe and effective alternative to ferric chloride and PAC for the coagulation of surface waters.
-
Oil, Gas & Petrochemical: Rapid oil-water separation (demulsification) and treatment of highly contaminated hydrocarbon wastewater.
-
Textile & Paper: A fixing agent for direct and reactive dyes and a retention aid for fibers on the wire.
-
Detergent & Personal Care: A softening and anti-static agent in fabric softener formulations.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This material is a skin and eye irritant. Please obtain the complete MSDS from Arnico for full first-aid measures.
-
Storage Conditions: Store away from direct sunlight and frost, at a temperature between +5°C and +35°C, in polyethylene, fiberglass, or stainless steel containers. Storage in iron or aluminum vessels must be strictly avoided.
-
Personal Protective Equipment (PPE): When decanting and handling, the use of rubber gloves, safety goggles, and workwear is mandatory.
6. Quality Assurance & COA
All Arnico PolyDADMAC shipments are accompanied by a validated COA, including precise results for viscosity, pH, and solid content based on ASTM standards. This ensures complete reproducibility of the customer’s coagulation process.
