반응 단계
To 56.9 g of a 37% aqueous solution of formaldehyde (formalin) adjusted to the pH of 8.6 by a 5% aqueous solution of sodium hydroxide, 22.6 g of melamine and 20.5 g of urea were added, mixed and dissolved at 50° C. with stirring, and water was added. After one hour, melamine-urea-formaldehyde prepolymer was obtained by cooling.
