Diacetone acrylamide
Overview
Diacetone acrylamide (DAAM) is a specialized monomer widely used in industrial applications due to its unique chemical properties. It is particularly valued for its ability to form cross-linked polymers, enhancing the durability and performance of adhesives and coatings. DAAM is synthesized through the reaction of acetone and acrylamide, resulting in a compound that combines the reactivity of acrylamide with the stability of ketone groups. This dual functionality makes it a preferred choice in formulations requiring both flexibility and strength.
Physical and Chemical Properties
Diacetone acrylamide is a white crystalline powder with a molecular weight of 169.22 g/mol. It has a density of 1.01 g/cm³ and melts at 56-58 °C. The compound is soluble in water and most organic solvents, including alcohols and ketones. One of its key properties is its ability to act as a cross-linking agent, which improves the mechanical and thermal stability of polymers. DAAM also exhibits excellent compatibility with other monomers, making it a versatile additive in various formulations.
Main Applications
DAAM is predominantly used in the production of adhesives and coatings, where it enhances bonding strength and resistance to environmental factors. It is also employed in textile finishing to improve fabric durability and in printing inks to ensure better adhesion and color retention. In addition, DAAM finds applications in the synthesis of specialty resins and as a modifier in polymer blends. Its ability to form stable cross-linked networks makes it indispensable in high-performance industrial materials.
Safety and Storage
Diacetone acrylamide should be handled with care to avoid inhalation or skin contact. Proper personal protective equipment (PPE), such as gloves and goggles, is recommended. The compound should be stored in a cool, dry place, away from direct sunlight and moisture. In case of accidental exposure, rinse affected areas with plenty of water and seek medical advice. Always follow local safety regulations and guidelines when handling DAAM to ensure safe usage and disposal.
B2B Procurement Guide
When procuring Diacetone acrylamide, it is essential to verify the CAS number (2873-97-4) and purity specifications. Reputable suppliers should provide certificates of analysis and comply with industry standards. Bulk purchases may offer cost advantages, but ensure proper storage conditions to maintain product integrity. Consider suppliers with a track record of reliability and those who offer technical support for formulation challenges.
