Chemical Properties

• Chemical Category: Monofunctional UV-curable monomer, acrylamide derivative, also known as N-Acryloylmorpholine (ACMO); with acryloyl and morpholine functional groups.
• Stability: Stable under normal temperature and pressure (sealed); usually stabilized with 1000 ppm MEHQ (monomethyl ether hydroquinone) to prevent polymerization; decomposes under strong acid/alkali or high temperature.
• Acid-Base Property: Neutral to weakly alkaline; stable in neutral and weakly alkaline environments, not easy to hydrolyze under normal conditions.
• Hydrolysis: Stable under normal storage conditions; no obvious hydrolysis; can be decomposed under strong acid/alkali and high temperature conditions.
• Photostability: Sensitive to light, especially ultraviolet light; long-term exposure to strong light may induce polymerization, affecting product performance.
• Reactivity: Contains reactive carbon-carbon double bond, easy to undergo polymerization reaction under UV irradiation or thermal initiation; low toxicity, but has certain irritation to skin and eyes; GHS hazard symbols include GHS05, GHS07, GHS08.

Chemical Structure

Applications

• UV curing industry: Used as UV-curable monomer, widely used in UV curing coatings, inks, adhesives and photoresists, improving the curing speed and product performance.
• Polymer synthesis: Used as monomer for polymer synthesis, used in the preparation of water-soluble polymers, hydrogels and other materials, with good biocompatibility.
• Pharmaceutical industry: Used as pharmaceutical intermediate, used in the research and development of drugs and biological reagents, providing functional groups for molecular modification.
• Coating industry: Used as additive in water-based coatings, improving the adhesion, flexibility and water resistance of coatings.
• Other fields: Used in scientific research experiments, as a reagent and solvent in organic synthesis; also used in the preparation of functional materials and electronic chemicals.

Storage & Handling

• Storage: Sealed, cool, dry and dark; away from sunlight, heat and oxidants; avoid polymerization caused by light and heat; keep away from open fire and high temperature sources.
• Temperature: 2-30 °C for long-term storage; refrigerated storage is recommended; shelf life 12 months under proper storage conditions; use as soon as possible after opening.
• Packaging: Sealed glass bottle or plastic drum (25kg/50kg); small packages adopt sealed aluminum foil bags, avoiding contact with air and light; marked with stabilizer content.
• Precautions: Operate in a well-ventilated environment; avoid inhalation of vapor and direct skin/eye contact; wear protective gloves, goggles and masks during operation; rinse with plenty of water immediately if contacted accidentally; dispose of waste in accordance with industrial waste regulations; avoid mixing with strong oxidants and initiators.
