Melamine was originally manufactured by heating dicyandiamide under pressure. Currently, melamine is produced by the decomposition of urea into cyanic acid and ammonia in an endothermic reaction. Cyanic acid is then polymerised to form melamine and carbon dioxide.

Its most important reaction is that with formaldehyde, forming resinous compounds of high molecular weight. The construction and automotive industries figure high in driving melamine growth. Container and coil coatings, laminates and flame retardant uses have all experienced growth in recent years.

Melamine is used in the production of moulding powder to make dinner ware, coatings in cars, fan coils and appliances. Other uses include adhesive resins, which are used in the making of wood panels for the construction of kitchens, bathrooms, furniture and flooring. Melamine is produced by heating urea, ammonia (NH3) and carbon monoxide, of which the resulting mixture of isocyanic and ammonia reacts over a solid catalyst at about 400ºC.

Melamine is moderately toxic by ingestion and a skin and eye irritant.
