Melamines (2,4,6-triamino-1,3,5-triazines) are produced from urea. They are used in the fabrication of melamine – formaldehyde resins for laminating and adhesive applications. Melanine is used as cross-linker in heat-cured and high-solids paint systems.

Guanamines (2,4-diamino-1,3,5-triazines) are produced from dicyandiamide and the corresponding nitrile by base-catalyzed cyclocondensation. They are used in similar polymer applications as for melamine. They give a lower cross-link density and higher flexibility because only two amino functionalities are present.
