Why choose PolyDADMAC Powder (CAS 26590-05-6) over the standard liquid solution?

The primary advantage is logistics and storage stability. While the liquid form is easier to dose directly, it is typically 50-80% water, leading to high shipping costs per unit of active ingredient. The Powder form represents 100% active material, offering significant freight savings and a longer shelf life, though it requires specialized makeup equipment to ensure complete dissolution without "fish-eyes" (undissolved gel lumps) prior to dosing.

Is this polymer capable of replacing inorganic coagulants like PAC or Alum?

In many cases, yes, or it can be used in conjunction to reduce dosage. PolyDADMAC functions via a charge neutralization mechanism similar to inorganic salts but produces significantly less sludge volume (as it does not add metal hydroxides to the solids). This makes it ideal for plants looking to minimize sludge disposal costs and improve the dewatering rate of the filter cake.

PolyDADMAC Powder CAS 26590-05-6

PolyDADMAC Powder CAS 26590-05-6 is a concentrated cationic quaternary ammonium polymer chemically defined as poly(diallyldimethylammonium chloride) , functioning primarily as a high-efficiency primary coagulant in potable water treatment and a charge-neutralizing agent in wastewater clarification. Unlike standard liquid grades (typically 20-50% active), this solid bead or granular form offers 100% active content, utilized to destabilize negatively charged colloidal suspensions and reduce sludge volume in dewatering processes. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications (varying intrinsic viscosity levels) for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

Applications

PolyDADMAC Powder is a versatile cationic polymer utilized in various industrial sectors:

1. Water & Wastewater Treatment:

Primary Coagulant: Destabilizes suspended solids and colloidal particles efficiently.
Sludge Dewatering: Enhances the filtration rate and cake dryness in belt presses and centrifuges.
Decolorization: Highly effective in removing color from textile dyeing wastewater and dye manufacturing effluents.

2. Paper & Pulp Industry:

Anionic Trash Catcher (ATC): Neutralizes interfering anionic substances in the wet end, improving the efficiency of other additives.
Retention & Drainage Aid: Increases the retention of fibers and fillers, speeding up the paper machine drainage.
Fixative: Improves the fixing of dyes and sizing agents to the fibers.

3. Textile Industry:

Fixing Agent: Used as a formaldehyde-free fixing agent for reactive and direct dyes, improving color fastness (wash and rub fastness).

4. Oilfield Chemicals:

Clay Stabilizer: Prevents clay swelling in drilling operations.
Water Clarification: Used in oil-water separation processes.

Quality Assurance (QA/QC)

Monomer Control (HPLC): We utilize High-Performance Liquid Chromatography (HPLC) to strictly monitor and minimize residual DADMAC monomer, ensuring the product is safe and environmentally compliant.
Molecular Weight Analysis: Gel Permeation Chromatography (GPC) is employed to verify molecular weight distribution, ensuring consistent flocculation performance batch after batch.
Impurity Screening: Every production run is tested for insolubles to prevent nozzle clogging in customer application systems.

Storage, Handling & Safety

Storage Conditions:

Hygroscopic Nature: PolyDADMAC powder is highly hygroscopic. Store in a cool, dry place ( $< 35^{\circ} C$ <35∘C) in original, sealed packaging.
Shelf Life: 24 months from the date of manufacture if stored correctly. Ensure bags are re-sealed immediately after partial use.
Incompatibility: Avoid contact with strong oxidizers, iron, copper, and aluminum containers during solution preparation (use plastic, fiberglass, or stainless steel).

Safety Precautions (HSE):

Slip Hazard: Warning: Spilled powder becomes extremely slippery when wet. Do not flush spills with water initially. Shovel or sweep up dry powder first, then scrub the area.
PPE Recommendations:
- Respiratory: Wear a dust mask (N95/P2) to prevent inhalation of fine particles.
- Eyes: Use chemical safety goggles.
- Skin: Wear protective gloves and long-sleeved clothing to avoid prolonged skin contact.
