N,N-Dimethylacrylamide (DMAA) monomer is a versatile chemical building block revolutionizing polymer synthesis across coatings, inks, adhesives, and other industrial applications. As a key product of Shenzhen U-Sunny's AM-317 series, DMAA offers unparalleled performance enhancements in material design. This article explores its properties, applications, and why U-Sunny's AM-317 stands out in the competitive chemical market.
. DMAA Monomer: Chemical Properties and Polymerization Advantages
DMAA (CAS No. 2680-03-7) is a colorless, water-soluble liquid with a molecular weight of 99.13 g/mol . Its unique structure-featuring both a double bond and an amide group-enables high reactivity in free-radical polymerization. Key physical properties include:
Boiling Point: 171–172°C at 760 mmHg
Density: 0.965 g/mL at 25°C
Viscosity: 1.3 cps (ultra-low, ideal for resin dilution)
Hydrophilicity: Exceptional moisture absorption, making it suitable for anti-fog coatings .
In polymer synthesis, DMAA enhances copolymer performance by improving mechanical strength, adhesion, and thermal stability. For example, grafting DMAA onto polyolefins boosts tensile strength, impact resistance, and anti-static properties .
2. Industrial Applications of DMAA Monomer
Coatings
DMAA-based UV-curable coatings are widely used in automotive and electronics due to their rapid curing (<30 seconds under 365 nm UV light) and low shrinkage (<3%) . U-Sunny's AM-317 series excels in high-temperature environments (stable up to 200°C), making it ideal for LED headlights and aerospace coatings .
Inks
In UV inks, DMAA improves adhesion to challenging substrates like polyethylene (PE) and polypropylene (PP) through micro-etching effects . Its low viscosity ensures smooth pigment dispersion, while fast curing accelerates production efficiency.
Adhesives
DMAA enhances adhesive performance by balancing hardness and flexibility. Studies show that adding 14% DMAA to acrylic pressure-sensitive adhesives increases peel strength to 32.10 N/24mm and heat resistance to 6 hours at 12mm . U-Sunny's AM-317 also supports eco-friendly formulations with near-zero VOC emissions .
