AEROTEX® NMA-LF Monomer

Allnex

AEROTEX® NMA-LF is specifically designed to provide effective selfcrosslinking performance together with a significant reduction in both the formaldehyde present in the resulting emulsion polymer and the formaldehyde released to the environment upon curing. AEROTEX® NMALF combines the cost effectiveness of AEROTEX® NMA with a dramatic reduction in total formaldehyde. The active self-crosslinking species of AEROTEX® NMA-LF is N-methylolacrylamide (NMA). NMA contains both a vinyl group and an N-methylol group. The vinyl group is reactive and enables the NMA to be readily incorporated into a variety of polymer backbones. Once incorporated into the polymer, the methylol group can be triggered to undergo crosslinking with itself, other functional groups in the polymer (such as hydroxyls or amines), or with cellulosic substrates. The bifunctional feature of AEROTEX® NMA-LF ultimately results in latex binders which provide important performance properties to the final product, such as wet strength, tear strength, and solvent resistance.
