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.

摘要： Described herein are resin products having particular utility as rapid curing adhesives for wood and other materials, and processes for making the resin compositions. The products are made by reacting aldehude condensation polymer containing reactive alkylol groups, such as a phenol-formaldehyde condensation polymer, with di-substitued bis-aryl amine having the formula:

WHERE R and R'' are alkoxy, amino, hydrogen, hydroxyl, nitro, carboxyl or C1 to C4 alkyl AND X is

to obtain an amine-modified polymer. When the resulting reaction product is blended with an appropriate curing agent, such as an aldehyde, the compositions cure very rapidly at ambient temperature. When pieces of wood or other materials are spread with the preferred adhesives employing the resin compositions of this invention and brought into contact with another wood surface the bond strength develops within minutes. The durability, strength and flexibility of the adhesives of this invention under adverse weathering conditions are excellent.
