Procedure

5.4 g of phloroglucinol and 0.6 g of melamine are dissolved in 78.6 g of distilled water. The pH is adjusted to 3 using 1.2 g of 85% strength formic acid. The mixture is heated to 35° C. and 14.2 g of 50% strength glutaraldehyde solution are added. After 5 minutes the soluble precondensate begins to form, evident from the dissolution of the melamine and phloroglucinol, which is barely soluble in water. The overall solids content of the precondensate is 14.0% by weight.
