Reaction Steps
Alternatively, the amino-formaldehyde resins of the disclosure that include melamine, and not urea, to form melamine-formaldehyde (MF) resins. Amino-formaldehyde resins may be prepared with a formaldehyde (F) to melamine (M) molar ratio (F:M) from about 2.5:1 to about 0.3:1, such as from about 1.4:1 to about 0.8:1, for example, about 1.1:1.
