ABSTRACT:
There are disclosed methods and compositions for accelerating the hardening of phenolic resole resins having a pH of about 4.5 to 9.5 with lightburned magnesium oxide or magnesium hydroxide, with or without the addition of an ester functional hardening agent. Acceleration of hardening is achieved by incorporating into said compositions an effective quantity of a material which: increases the solubility of magnesium in the hardenable mixture; by certain amines; or by certain chelating agents. Accelerator compounds include those which provide chloride, sulfamate, nitrate, formate, and phosphite anions as well as selected tertiary amines.
