What is n-methylolacrylamide?
N-Methylolacrylamide (CAS 924-42-5), abbreviated NMA, is a reactive acrylamide monomer used to introduce crosslinking functionality into polymer systems.
Where is n-methylolacrylamide used?
- Textile finishing: incorporated into binder systems and crease-resist treatments, crosslinking with cellulosic fibers for dimensional stability and wrinkle recovery
- Paper and nonwovens: improves wet strength by anchoring polymer networks within the fiber matrix
- Emulsion polymerization: reactive comonomer that builds in latent crosslink sites activated during film formation or heat curing
- Coatings and leather finishing: NMA-modified binders improve adhesion and abrasion resistance of topcoats
- It enables covalent bonding between polymer chains or between polymers and substrates.
Good to know: Proper storage and handling are required to maintain the stability of the aqueous solution.
Commercial specifications
- Aqueous solution, 48% and 60% concentrations
- Packaging: drums to IBC totes, bulk options
