Product Information
CAS 127-19-5 N,N-Dimethylacetamide is a colorless, water-miscible with a high high boiling liquid is commonly used as a polar solvent in organic synthesis. Dimethylacetamide is a medium potency reproductive toxicant.
DMAC is less toxic than DMF. The good water solubility and excellent solvent power, particularly for high molecular weight polymers and resins, make DMAc as a common solvent in man-made fibre and polyurethane production.
Applications of Dimethylacetamide CAS 127-19-5
DMAC Solvent for Resin
N,N-Dimethylacetamide (DMAc) is a powerful, high-boiling, polar aprotic solvent widely used to dissolve high-performance resins like polyimide, polyurethane, and acrylics.
Key Applications of DMAc in Resin Industry
- Polyimide Resins: Used in the production of coatings, films, and electrical insulation.
- Polyurethane (PU): Acts as a primary solvent for spandex and other PU-based elastane fibers in wet and dry spinning.
- Acrylic & Vinyl Resins: Used in the production of polyacrylonitrile fibers and various vinyl resin coatings.
- Other Polymers: Effective for cellulose-based materials (often with Lithium Chloride) and linear polyesters.
