A process for attaching a modifying agent to a substrate surface comprises the steps of: A. Contacting in an inert gas atmosphere a substrate with a modifying agent, an optional binding agent, and a liquid mixing agent to form a first substrate mixture; B. Evaporating at least a part of the liquid mixing agent while agitating the first substrate mixture under an inert gas flow or a partial vacuum to form a semi-crystalline coating of modifying agent on the substrate surface; C. Contacting the modifying agent semi-crystalline coating on the substrate surface with additional mixing agent to remove at least a portion of the coating from the substrate surface and to form a second substrate mixture comprising removed modifying agent, substrate and additional mixing agent; D. Agitating the second substrate mixture under an inert gas flow or a partial vacuum to form a semi-crystalline coating of the removed modifying agent on the substrate surface; and E. Recovering the substrate with the modifying agent coating.
