A method of pretreating coal fly ash is presented having an essentially monomolecular partial coating of under 100 angstroms thickness for obtaining improved compatibility with organic polymers and resins. The partial coverage is selected from the long-chain organic group including organotitanates, organofunctional silanes and stearic acids, with the former being preferable. The amount of chemical pretreatment compound required is preferably from 0.01 to 0.09 parts, per 100 parts of coal fly ash.
