    摘要: Disclosed are liquid, curable adhesives having a pH of less than 3.5 and comprising an aldehyde condensation polymer and a finely divided metal selected from aluminum and iron. Such adhesives are particularly useful for application to cellulosic substrates such as wood. When the cured adhesive is subjected to hydrolytic conditions, the finely divided metal reacts with hydrogen ions leached from the adhesive and thereby prevents or markedly reduces degradation of the cellulosic substrate.
