Dadmac (Quaternary Ammonium Monomer) DADMAC is a high purity, aggregated, quaternary ammonium salt and high charge density cationic monomer. Its appearance is colorless and transparent liquid without an irritating smell. DADMAC can be dissolved in water very easily. There is alkenyl double bond in the molecular structure and can form linear homopolymer and all kinds of copolymers by various polymerization reaction. The features of DADMAC are: very stable in normal temperature, unhydrolyzed and noninflammable, low irritation to skins and low toxicity. Use: It can be used as cationic monomer to produce mono-polymer or co-polymers with other monomers. The polymers can be used as formaldehyde-free color-fixing agent in the textile dyeing and finishing auxiliaries, film forming on the fabric and improve the color fastness; In paper-making additives can be used as retention agent, paper coating anti-static agent, AKD sizing promoter; Can be used in decoloring flocculation in the process of water treatment and purification with high efficiency and non-toxic;In daily chemicals, can be used as shampoo combing agent, wetting agent and the anti-static agent; In oilfield chemicals can be used as clay stabilizer, cationic additive in acid and fracturing fluid and so on. Its main role is electric neutralization, adsorption, flocculation, cleaning, decoloring, especially assynthetic resin modifier for conductivity and anti-static property.
