CATEGORY

N,N-dimethylacrylamide (DMAA) is an acrylamide-based UV monomer suitable for photocuring reactions. It has strong thinning and viscosity-reducing abilities and excellent compatibility with various UV resins. DMAA has a micro-etching, swelling, and bonding effect on polyolefins, unsaturated polyesters, ABS, PC, PMMA, untreated PET, and even PP and PE, as well as on various plastic films, thus better promoting adhesion.

Function

1. Ultraviolet/Electron Beam (UV/EB) Curing

Coatings and Inks: Low viscosity and high reactivity make it suitable for formulation of UV-curable coatings, adhesives, and printing inks.

Optical Materials: Due to its high transparency and low shrinkage, it is used in precision materials such as lenses and optical films.

2. Oil and Gas

Drilling Fluids: Enhances the temperature and salt resistance of polymers in cementing and filtration control.

3. Healthcare

Medical Gels: Used in wound dressings, contact lenses, and other biocompatible hydrogels.

4. Industrial Chemicals

Paper Strengthening Agents: Improves the dry strength of paper.

Water Treatment: Used as a flocculant for removing heavy metals in copolymers.

Textile Printing and Dyeing: Used as a crosslinking agent to improve fiber wrinkle resistance and dye fixation.
