INCI/Chemical Name:
Mixture of methylacrylamide and acrylamide in water
Item code:
BP204368
AEROTEX NMA 48%, offered as a 48% aqueous solution, is a bifunctional monomer possessing both vinyl and hydroxymethyl groups.
Thermoplastic polymers can be formed through the copolymerization of NMA with a variety of vinyl monomers via emulsion, solution, or suspension techniques.
The resulting products, having pendant hydroxymethyl groups, are self-crosslinkable under moderate conditions.
This mechanism permits the conversion of thermoplastic backbone polymers to thermoset materials at the point of use without the need for an external crosslinker.
Conversely, the hydroxymethyl group can first be reacted with a substrate like cellulose and subsequently cross-linked by free radical polymerization.
Description of AEROTEX NMA:
AEROTEX NMA 48%, offered as a 48% aqueous solution, is a bifunctional monomer containing both vinyl and hydroxymethyl groups.
AEROTEX NMA-LF is specifically designed to provide effective self-crosslinking performance along with significant reduction of both formaldehyde present in the resulting emulsion polymer and formaldehyde released to the environment during cure.
AEROTEX NMA-LF combines the cost effectiveness of AEROTEX NMA with a drastic reduction in total formaldehyde.
The active self-crosslinking species of AEROTEX NMA-LF is N-methylolacrylamide (NMA).
NMA contains a vinyl group and an N-methylol group.
The vinyl group is reactive and allows NMA to be easily incorporated into a variety of polymer structures.
Once incorporated into the polymer, the methylol group can be activated to cross-link with itself, with other functional groups in the polymer (such as hydroxyls or amines), or with cellulosic substrates.
AEROTEX NMA-LF Monomer (ROW) by allnex is N-methylolacrylamide based monomer.
AEROTEX NMA is specifically designed to provide effective self-crosslinking 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 NMA's bifunctional feature results in latex binders which provide important performance properties to the final product such as solvent resistance, wet- and tear strength.
AEROTEX NMA-LF Monomer (ROW) is used as binders in papermaking, textiles & non-wovens to a variety of surface coatings and resins for varnishes, films and sizing agents.
The shelf life of this product is 240 days.

APPLICATION AREAS OF AEROTEX NMA:
The applications of AEROTEX NMA 48% range from adhesives and binders in papermaking, textiles, and non-wovens to a variety of surface coatings and resins for varnishes, films and sizing agents.
STABILITY AND STORAGE OF AEROTEX NMA:
AEROTEX NMA 48% is highly reactive, thus, it is essential that precautions be taken to maintain stability during shipping and storage.
The stability of the solution is dependent mainly upon oxygen level, contaminants, storage temperature, and pH.
AEROTEX NMA 48% has a shelf life of 270 days from the date of manufacture and should be stored in a cool place where the temperature range is between 0°C and 29°C.
The expiration date may be extended and COA updated after QC testing of retained samples, only for material in allnex possession.
SAFETY AND HANDLING OF AEROTEX NMA:
Please consult the Safety Data Sheet (SDS) for safety, health, and environmental data available from allnex.
INTRODUCTION TO AEROTEX NMA:
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 NMA-LF combines the cost effectiveness of AEROTEX NMA with a dramatic reduction in total formaldehyde.
The active self-crosslinking species of AEROTEX NMA-LF is Nmethylolacrylamide (NMA).
NMA contains both a vinyl group and an Nmethylol 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.
