Diacetone Acrylamide (DAAM), with the CAS number 2873-97-4, is a versatile organic compound featuring two reactive functional groups: an N-substituted amide and a ketone. This unique structure allows it to participate in copolymerization with various vinyl monomers, introducing ketone carbonyl groups into polymers. These carbonyl groups enable subsequent cross-linking reactions, enhancing the performance of materials like adhesives, thickeners, paper strengtheners, and cross-linking agents. DAAM is widely used in coatings, adhesives, daily chemicals, epoxy resin curing agents, photosensitive resin additives, textile auxiliaries, and medical hygiene products. Its compatibility with water and organic solvents, such as methanol, ethanol, acetone, and tetrahydrofuran, further expands its applicability.
Properties and Applications of DAAM
DAAM appears as white or slightly yellow flaky crystals. It has a melting point of 53-57°C and a boiling point of 120°C (at 8 mmHg). Its solubility in water and various organic solvents makes it suitable for diverse formulations. One notable characteristic of DAAM-based polymers is their “water-breathing” property, absorbing 20%-30% of their weight in moisture and releasing it when humidity drops below 60%. This feature is beneficial in hair spray fixatives and photosensitive resins. In photosensitive resins, DAAM polymers contribute to high light sensitivity, clarity, and resistance to solvents and water. Additionally, DAAM serves as a curing agent for epoxy resins, antifouling coatings, and acrylic resin coatings. It is also used in clarifying suspended solids, laser recording materials, glass anti-fogging agents, and azo copy materials.
Synergy with Adipic Dihydrazide (ADH)
Adipic Dihydrazide (ADH), with the CAS number 1071-93-8, is a white crystalline compound soluble in water. It functions as a bifunctional cross-linking agent, particularly effective with aldehydes to form stable hydrazone linkages. In combination with DAAM, ADH plays a significant role in post-cross-linking of water-based emulsions and polymers. This synergy is leveraged in水性涂料 (water-based coatings), adhesives, fiber and plastic film treatments, and hair sprays. ADH is also employed as a latent curing agent for epoxy powder coatings, contributing to flexibility, water resistance, weather resistance, corrosion protection, insulation, and decorative properties. Furthermore, ADH is used in protein drug carriers via cross-linking with sodium hyaluronate, formaldehyde adsorbents, and intermediate materials.
Advantages and Safety
DAAM and ADH offer advantages such as enhanced polymer performance, flexibility in formulation, and broad applicability. DAAM has low toxicity, with an oral LD50 of 1770 mg/kg for rats, and zero skin and eye irritation indices. ADH requires careful handling due to its moderate toxicity. Both chemicals should be stored in cool, dry conditions to maintain stability.
