    DADMAC CAS 7398-69-8

    DADMAC (CAS 7398-69-8) is a high-purity quaternary ammonium salt specifically utilized as a cationic monomer for the synthesis of advanced polyelectrolytes and coagulants. This Diallyl Dimethyl Ammonium Chloride is characterized by its high charge density and hydrolytic stability, serving as the essential precursor for producing PolyDADMAC used extensively in industrial water treatment and sludge dewatering applications. In papermaking and textile sectors, this Dimethyldiallylammonium Chloride functions as a critical fixing agent and retention aid, ensuring process efficiency in high-speed manufacturing environments. To accommodate diverse polymerization requirements, we offer reliable bulk supply of various aqueous solution grades. Our integrated supply chain guarantees competitive factory pricing for international partners, accompanied by full regulatory support including MSDS, TDS, COA. Furthermore, we maintain the flexibility to provide customized specifications regarding active content and pH levels to align with precise formulation parameters.

    Product Description

    Product Introduction
    [CAS ] 26062-79-3

    [Molecular formula] (C8H16NCl)n
    【Performance】

    This product is a strong cationic polyelectrolyte, the appearance is a colorless to light yellow viscous liquid, the freezing point is about -2.8°C, the specific gravity is about 1.04g/cm3, and the decomposition temperature is 280-300°C. It is soluble in water, non-flammable, has strong cohesion, has good hydrolysis stability, does not form a gel, is insensitive to PH changes, and is chlorine resistant. This product is non-toxic, has no adverse reactions to the human body, and is the only synthetic cationic quaternary ammonium salt polyelectrolyte approved by the United States Public Health Service (USPHS) for drinking water purification process, which is safe and reliable to use and has mild corrosion. In water treatment, this product has both strong electricity neutralization and suction and bridging effect, so it has good flocculation and sedimentation performance. It also has obvious effects on decolorization, algae killing, and organic matter removal. It is usually used in combination with polyaluminum chloride.

    use

    It is used as a water purification coagulant in drinking water and cooling water treatment, and can also be used as a biocide, which can kill or inhibit the growth of various bacteria and algae, and is also an effective slime control agent.

    How to use:

    Before getting on the machine, conduct a small test to determine the application method and dosage.

    Packaging & Storage

    200L PE plastic drum, 200kg/drum; 1000L IBC drum, 1000kg/drum.
    Sealed packaging, sealed and stored, avoid contact with strong oxidants.
    It is valid for two years and can be transported as non-dangerous goods.

    FAQ - Technical & Supply Chain

    • Q:

      Is DADMAC the same as polyDADMAC?

      A: No. DADMAC is the monomer form, while polyDADMAC is the polymer produced from DADMAC and has a different chemical identity and CAS number.
    • Q:

      Is DADMAC mainly used as an industrial monomer rather than a finished product?

      A: It is commonly supplied as an industrial monomer for polymerization and formulation processes rather than as a finished end‑use product.
    • Q:

      What is the primary technical advantage of incorporating DADMAC into copolymer systems?

      A: DADMAC provides a high-density, pH-independent cationic charge.Unlike hydrolyzable monomers (such as certain cationic acrylamides), the quaternary ammonium group in DADMAC remains stable and fully ionized across a broad pH range (typically 1–14). This stability is the critical technical requirement for polymers utilized in harsh industrial water treatment or alkaline papermaking environments.
