Durite™ Resin AD-3231


AD-3231 is a pulverized, heat resistant, phenolic resin of the two-step type.


AD-3231 was specifically developed as a general-purpose bond for resinoid grinding wheels. It provides an optimum balance of room temperature, elevated temperature and wet strength properties. Used in conjunction with phenolic and/or furfural wetting agents, it has been used successfully as a bond in most types of grinding wheels.
