/mel"euh meen', mel'euh meen"/, n. Chem.
1. a white, crystalline, slightly water-soluble solid, C3N3(NH2)3, used chiefly in organic synthesis and in the manufacture of resins, esp. melamine resins.
2. any of the melamine resins.
[1825-35; < G Melamin, deriv. of Melam distillate of ammonium thiocyanate (arbitrary coinage, but -am repr. AMMONIUM); see -INE2]

also called  cyanuramide , or  triaminotriazine 

      a colourless, crystalline substance belonging to the family of heterocyclic organic compounds, which are used principally as a starting material for the manufacture of synthetic resins.

      Melamine is manufactured by heating dicyandiamide under pressure. Its most important reaction is that with formaldehyde, forming resinous compounds of high molecular weight. These resins form under the influence of heat but, once formed, are insoluble and infusible. Usually formulated with fillers and pigments, they are molded into dishes, containers, utensils, handles, and the like or used as laminating agents or coating materials for wood, paper, and textiles. Formica and Melmac are well-known trade names for products based on melamine resins.

      Butylated melamine resins, made by incorporating butyl alcohol into the melamine–formaldehyde reaction mixture, are fluids used as ingredients of paints and varnishes.
