FAQ - Technical & Supply Chain
-
Q:
Are N-Methylolacrylamide and N-(Hydroxymethyl)acrylamide the same substance?
A: Yes. Both names identify CAS 924-42-5, commonly abbreviated NMA. It is not N-methylacrylamide, which lacks the hydroxymethyl group. Purchase documents should state the complete name, CAS number and supplied form because the abbreviation NMA alone can also be used for other materials. -
Q:
Which specifications should be agreed for N-Methylolacrylamide?
A: First define solid NMA or an aqueous solution and its concentration. Then agree assay or solids, free formaldehyde, water, pH, color, inhibitor and relevant acrylamide-related impurities, with the test method and reporting basis. Compare the batch COA with the approved form-specific specification rather than a nominal purity alone. -
Q:
What should be confirmed for NMA packing and storage?
A: Specify container size, liner or drum compatibility, inhibitor system, allowable temperature range, production date and maximum storage period. Protect the material from heat and uncontrolled polymerization conditions, and avoid contamination during sampling. The receiving procedure should follow the current SDS and the storage conditions documented for the actual solid or solution grade.
