AQUADERM^® Fluid H is a flow control agent which is mainly used in aqueous top lacquer formulations. It considerably improves the flow even of difficult formulations without impairing the physical fastness properties. If a finish containing AQUADERM^® Fluid H is to be oversprayed, it is important to ensure that the top finish also contains AQUADERM^® Fluid H, as otherwise there may be problems with the flow of the final coat.
