ABSTRACT:
A Method of coating particulate materials (such as silica sand, glass beads, seeds and metal particles) with a liquid thermosetting epoxy resin which comprises agitating the epoxy resin with the particles in a nonpolar liquid, which is immiscible with the epoxy resin, and contains a nonionic surfactant having a molecular weight of at least 2,000 to retard the tendency of the epoxy coated particles to agglomerate during curing of the resin in the non-polar liquid. A suitable liquid for use as the immiscible liquid is a paraffinic oil which is aromatic-free and olefin-free.
