Chemical Structure
Basic Info
For water treatment chemical procurement managers and polymer R&D engineers, purchasing bulk cationic monomers requires evaluating critical quality indicators far beyond the standard price per metric ton. Because this high-charge density monomer serves as the backbone for synthesizing PolyDADMAC and water-soluble flocculants, exact active assay content and ultra-low free amine/dimethylamine hydrochloride contamination dictate your final polymerization efficiency.
Sourcing from unverified, low-tier chemical brokers often introduces material with erratic pH profiles or excessive residual salts. These hidden defects can disrupt polymerization kinetics, limit the molecular weight of your downstream polymers, or cause unreacted monomer carryover that violates strict environmental discharge regulations for municipal wastewater processing.
Our Diallyldimethylammonium Chloride (DADMAC, CAS 7398-69-8) is manufactured using an advanced, highly controlled alkylation and crystallization-purification pathway. We guarantee a clear, high-purity aqueous monomer profile (available in standard 60% and high-concentration 65% active content grades) with negligible free amine thresholds. This translates to predictable polymerization conversion rates, high cationic charge density, and excellent storage stability in your factory chemical tanks.

Product Packaging
1. PolyDADMAC Synthesis & Water Treatment Coagulants
In the water purification and municipal wastewater treatment sectors, DADMAC is the essential building block for producing PolyDADMAC. Its high cationic charge density effectively neutralizes the negative surface charges of suspended colloidal particles, accelerating micro-floc formation and clarifying turbid water. Our low-impurity monomer ensures that synthesis teams can consistently achieve high molecular weights, maximizing the filtration efficiency of finished dewatering and sludge conditioning formulations.
2. Retention Aids & Fixative Agents in Paper Manufacturing
The pulp and paper industry utilizes polymers synthesized from DADMAC as highly effective anionic trash catchers (ATC) and wet-end retention aids. By binding with negative wood fibers and filler minerals, it boosts paper machine drainage rates, improves sheet formation, and fixes pitch and size molecules onto the fibers. Sourcing teams rely on our low-color APHA monomer to prevent yellowing or brightness loss in premium white paper grades.
3. Dye Fixatives, Textile Auxiliaries & Personal Care Conditioning
In textile wet processing, DADMAC-derived polymers act as powerful formaldehyde-free dye-fixing agents for direct and reactive dyes, significantly improving color fastness against washing and friction. Furthermore, high-purity cosmetic-grade variants are copolymerized into acrylamide structures (Polyquaternium-7) to serve as antistatic, detangling conditioning agents in commercial shampoos, hair rinses, and skincare formulations.
FAQ
A: The primary operational advantage is polymerization kinetics and freight optimization. The 65% high-concentration DADMAC grade contains less water, allowing polymer chemists to achieve higher solid-content formulations and accelerate reaction velocity during homopolymerization or copolymerization. Additionally, it lowers international shipping and warehousing costs per active unit of chemical.
A: DADMAC is structurally stable but should be stored in a cool, well-ventilated warehouse away from direct sunlight, strong oxidizing agents, and copper or iron contamination, which can catalyze degradation. Maintain temperatures between 5°C and 30°C, and ensure storage tank materials are constructed from corrosion-resistant plastics (HDPE, PVC) or stainless steel (SS316L).
A: We provide standard 500ml to 1L technical evaluation samples packed in airtight fluorinated bottles for laboratory test-polymerizations. For bulk commercial contracts, standard spot stock can be dispatched from our seaport staging yards within 7 to 10 business days of contract finalization.
