  • Patent number: 3947425
    Abstract: Described herein are hydrophilic resin products having particular utility in rapid curing adhesives for wood and other materials. Processes for producing these resins and hydrophilic adhesives produced therefrom are also described. The resins are prepared by reacting an aldehyde condensation polymer, such as a phenol-formaldehyde condensation polymer, with a strong mineral acid salt, i.e., a hydrochloric, nitric, or sulfuric acid salt, of m-hydroxy aniline, 2,6-diaminopyridine or 4,4'-diaminodiphenylmethane. When these resins are blended with an appropriate curing agent, such as an aldehyde, the resulting adhesives cure very rapidly at ambient temperatures. While uncured, these adhesives are hydrophilic and thus water washable, but when cured, they are insoluble in water and common organic solvents.
