product description
Melamine is a trimer of cyanamide, with a 1,3,5-triazine skeleton. It has a role as a xenobiotic metabolite. It is functionally related to a cyanamide. It is a conjugate base of a melamine(1+).

Melamine: A white crystalline compound,C3N6H6. Melamine is a cycliccompound having a six-memberedring of alternating C and N atoms,with three NH2 groups. It can becopolymerized with methanal to givethermosetting melamine resins,which are used particularly for laminatedcoatings.

Product Usage

It is used to make high-pressure laminating resins (e.g., decorative countertops), molded compounds (e.g., dinnerware), and surface coating resins (e.g., appliance finishes and automotive topcoats). Additional major products are textile and paper treatment resins. Miscellaneous uses include adhesive resins for gluing lumber, plywood, and flooring, and resins for leather tanning agents. Melamine, melamine cyanurate, other melamine salts, and guanidine compounds are currently the most used group of nitrogencontaining flame retardants. Melamine is used as a flame retardant additive for polypropylene and polyethylene. Melamine cyanurate is employed commercially as a flame retardant for polyamides and terephthalates.
