Abstract
Abstract A composition having a high content of an inorganic material comprising (1) a granular or powdery phenol-aldehyde resin which is a condensation product of a phenol, an aldehyde and optionally a nitrogen-containing compound having at least two active hydrogens and is characterized by (A) containing spherical primary particles and their secondary agglomerated particles each having a particle diameter of 0.1 to 150 microns, (B) having such a size that at least 50% by weight thereof can pass through a 100 Tyler mesh sieve, and (C) having a free phenol content, determined by liquid chromatography, of not more than 500 ppm, and (2) a powder of an inorganic material, the amount of the phenol-aldehyde resin being less than 11% by weight based on the total weight of the phenol-aldehyde resin (1) and the powdery inorganic material (2).
