The coatable compositions of the invention suitable for reducing dust generation during processing of granular materials consist essentially of a tackifier, an organic oil, and an adhesion agent, the tackifier consisting essentially of an organic material having a glass transition temperature of no less than about 120°C and a diluent present in sufficient amount to give the tackifier a kinematic viscosity ranging from about 3,000 to about 5,000 centistokes at 100°C. The tackifier is preferably present in the composition at about 0.5 to about 2.0 weight percent of the total weight of the composition, and the adhesion agent is preferably present at about 0.5 to about 5.0 weight percent of the total weight of the composition, with the balance being organic oil. Granular materials having coatings of the composition (with or without the adhesion agent, are presented, as well as methods of reducing dust generation during processing and/or transport of granular materials and methods of making organic oil-coated granular materials.
