Coating formulations and method of making thereof for reducing the drag or friction encountered at the interface of a soluble drag reduction material coating and the liquid medium such as water in which the coating is being used. This is accomplished by adding various solid water-soluble materials as diluents and viscosity reducers, to a very high molecular weight drag reduction non-ionic polymer such as that of polyethylene oxide. The molded polymer with the added solid water-soluble material has less solubility and viscosity at and contiguous to the coating-water interface than that of the additive-free matrix under similar conditions.
