CAS 108-78-1 Melamine powder with the formula C3H6N6 is an organic compound. This white monocline crystal is a trimer of cyanamide. Melamine powder is used principally as a starting material for the manufacture of synthetic resins. Its products have excellent heat resistance, flame resistance and good mechanical strength. Melamine is rich in nitrogen, a property that is similar to protein. It is almost tasteless, slightly soluble in water (3.1g/L room temperature), soluble in methanol, formaldehyde, acetic acid, thermoethylene glycol, glycerin, pyridine, etc., insoluble in acetone, ether, harmful to the body, can not be used in food processing or food additives.
CAS 108-78-1 Structure:


What is melamine powder (cas 108 78 1) used for?
1. Plastics and Laminates
Melamine is mainly used to produce melamine-formaldehyde (MF) resin, a thermosetting plastic with durability, heat resistance and water repellency. Key applications: high-pressure laminates (HPL) for furniture, flooring and wall panels; molded products (dinnerware, kitchenware, electrical insulation); industrial adhesives for engineered wood and fiberboards.
Melamine plastic uses: shatterproof tableware (households, restaurants), food-safe containers, electrical sockets/switchboards (insulation). Advantages over standard plastics: better heat resistance, chemical stability and strength, suitable for daily use.
2. Coatings and Paints
Melamine-based coatings feature high gloss and wear resistance, applied in: automotive finishes (scratch/heat protection), wood furniture/flooring coatings (durability/water resistance), industrial coatings for appliances/heavy machinery (harsh environment resistance).
Also used in heat-resistant paints, weatherproof coatings and industrial finishes requiring long-term protection against moisture, chemicals and temperature fluctuations.

3. Construction Materials
Widely used in engineered wood (MDF, particle boards) as a protective laminate, for kitchen/bathroom cabinetry, office furniture, bookshelves, partition walls and decorative panels.
Its flame-retardant property makes it key in fireproof panels for commercial/industrial buildings, used in ceiling systems, wall insulation and public spaces (auditoriums, hospitals) with strict fire safety requirements. Preferred for sustainable, durable and fire-resistant building materials.
