Core applications of hexamine
Hexamine's versatile chemistry makes it indispensable across a broad range of industrial sectors. Its principal applications include:
Phenolic Resins & Moulding Compounds
Hexamine is widely used as a hardening/curing agent in the production of phenolic resins and moulding compounds, providing strength, dimensional stability and durability to finished products. This is hexamine's largest single industrial application.
Binders, Adhesives & Abrasives
Hexamine serves as an effective binder in brake linings, clutch facings and abrasive products, enhancing structural integrity under thermal and mechanical stress.
Solid Fuel Tablets
A common component in solid fuel tablets used for camping stoves, military rations and small-scale heating – providing a clean, efficient, smokeless heat source.
Rubber Processing
Hexamine acts as a vulcanisation accelerator in rubber manufacturing, contributing to material elasticity and strength.
Pharmaceutical (Methenamine)
As methenamine, hexamine is used as an antibacterial agent prescribed for urinary tract infections – a long-established pharmaceutical application.
Speciality Chemical Manufacture
Used as an intermediate in the manufacture of various nitrogen-containing speciality chemicals and corrosion inhibitors.
Compliant Hexamine Supply
Hexamine is classified as a regulated explosives precursor under EU Regulation 2019/1148 (and the corresponding UK regime), meaning its supply to the general public is restricted. East Harbour Group supplies hexamine strictly to legitimate commercial and industrial customers, with full Know-Your-Customer documentation, end-use verification and traceability across the supply chain. This compliant supply position is a positive trust signal for legitimate buyers – procurement and quality teams in resin manufacturing, rubber processing, fuel manufacturing, pharmaceuticals and other regulated industries.
What is the CAS Number of Hexamine?
The UN number for Hexamine is UN1328. This internationally recognised identifier is assigned by the United Nations for the transport of dangerous goods. UN1328 refers to “Hexamethylenetetramine” and applies to commercial hexamine across ADR/RID (road), IMDG (sea) and IATA (air), ensuring correct identification, packaging and handling throughout the supply chain.
What is the UN Number of Hexamine?
The CAS number of Hexamine (also known as methenamine, hexamethylenetetramine or HMT) is 100-97-0. This unique Chemical Abstracts Service identifier is used to recognise the substance across chemical databases and regulatory systems worldwide. The corresponding EINECS (EC) number is 202-905-8.
What is the Hazard Class and packing group of Hexamine?
Hexamine is assigned Hazard Class 4.1, identifying it as a flammable solid. At its supplied form (Coarse Crystalline, ≥99.0% purity), it is classified under Packing Group III, signifying a lower level of transport danger relative to Packing Groups I and II. UN number is 1328 across ADR/RID, IMDG and IATA. Always handle in accordance with the Safety Data Sheet.

FAQs
Under the European GHS / CLP classification system used by East Harbour Group, Hexamine is classified as H228 (Flammable Solid) and H317 (May cause an allergic skin reaction). The corresponding US NFPA 704 ratings are typically Health 2 (moderate hazard), Fire 3 (combustible), Reactivity 0 (stable). Hexamine should be handled in accordance with the Safety Data Sheet, with particular attention to dust-control measures – airborne hexamine dust can form flammable or explosive mixtures with air.

Yes. We supply hexamine in 25kg bags, drums and Intermediate Bulk Containers (IBCs) for larger volumes. Bulk supply is available across the UK and Europe by road, with sea and air freight options for international destinations. Contact our team for volume-tiered pricing and lead times.
Hexamine should be stored in the driest possible atmosphere (below 60% relative humidity), in sealed packaging away from heat, sparks and open flames. Pallets should not be double-stacked. Hexamine dust can form flammable or explosive mixtures with air – anti-static handling, explosion-proof equipment and good ventilation are essential. Always consult the Safety Data Sheet.
