Hexamethylenetetramine

Hexamethylenetetramine (CAS 100-97-0), commonly known as hexamine or HMTA, is a nitrogen-rich cyclic compound used industrially as a curing agent, crosslinker, and biocidal preservative.

Where is Hexamethylenetetramine used?

• Rubber and tire production: vulcanization accelerator and crosslinking agent for resorcinol-based adhesion systems, improving fiber-to-rubber bonding in belts and tires
• Phenolic resins: primary curing agent for novolac resins, enabling molding compounds, abrasive wheels, and friction materials
• Pharmaceuticals: urinary tract antiseptic active ingredient and tablet excipient
• Leather and textile processing: biocidal preservative and crosslinking agent in tanning and finishing formulations
• It reacts with phenolic resins and releases formaldehyde in a controlled way.

Commercial specifications

• Purity: 98% to 99.5% for industrial supply
