Description and Uses
Melamine-formaldehyde resin (MFR) is an active ingredient of strong (reinforced) plasters. Sensitization was reported in a plaster-room technician, who applied resin-reinforced pIaster casts, and in dental technicians. MFR was contained in a strong dental pIaster used for mouldings. Used as a textile finish res in, it was also found to be an allergen in a women who replaced clothes in a store. MFR also releases formaldehyde, which may be the sensitizer.
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.
