Reaction Steps

Six hundred and thirty grams of melamine and 1620 g of formalin (an aqueous 37% solution of formaldehyde) adjusted to pH of 9.0 by an aqueous 2% solution of sodium hydroxide were mixed, and the thus obtained mixture was heated to 70° C. Just after the dissolution of melamine, 2250 g of water were added to the thus obtained solution and the whole mixture was stirred for 3 min to obtain an aqueous solution of melamine-formaldehyde prepolymer.
