Frequently Asked Questions (FAQs)
What is Methenamine?
Methenamine, or Hexamethylenetetramine, is a heterocyclic amine with formula C₆H₁₂N₄ and CAS 100-97-0, used as a curing agent and antiseptic. It’s a white powder that cross-links resins and releases formaldehyde for preservation.
How is Methenamine used in phenolic resins?
Add 10-15% to resin mixes at 90-110°C; it decomposes to ammonia and formaldehyde, catalyzing cross-linking for rigid, heat-resistant composites.
Is Methenamine safe for pharmaceutical use?
Yes, it’s USP-monographed for oral antiseptics up to 1 g/dose, with low systemic absorption and no ADI limit per JECFA.
What is the shelf life of Methenamine?
In sealed, dry conditions below 30°C, it remains stable for 2-3 years, resistant to sublimation with minimal moisture absorption.
Can Methenamine be used in food-contact materials?
Methenamine is GRAS for indirect additives like resin stabilizers up to 0.5%, ensuring no migration in packaging applications.
Does Methenamine affect pH in formulations?
Its neutral pH (7.0-8.0) has minimal impact, but reactions may slightly acidify—buffer as needed for sensitive systems.
What packaging options are available for Methenamine?
We supply 25kg multi-wall bags, 50kg fiber drums, and 1000kg supersacks, all desiccated for humidity protection.
For curing profiles, safety data, or custom particle sizes, our specialists provide tailored expertise.
