Aminoresins melamine-formaldehyde resins

Melamine reacts similarly to produce methylol derivatives, which form the familiar melamine—formaldehyde resins on heating (63) (see Aminoresins). 

Aminoresins or aminoplastics cover a range of resinous polymers produced by reaction of amines or amides with aldehydes [14,46,47]. Two such polymers of commercial importance in the field of plastics are the urea-formaldehyde and melamine-formaldehyde resins. Formaldehyde reacts with the amino groups to form aminomethylol derivatives which undergo further condensation to form resinous products. In contras to phenolic resins, products derived from urea and melamine are colorless.
