THE BEHAVIOUR OF DEWATERING FORMULATIONS

Introduction In engineering practice it is necessary to distinguish between the requirements of ‘on line’ dewatering, where water is to be removed between two stages of a treatment process, and dewatering prior to storage. In the latter instance, a dewatering preservative is frequently used, obviating the need for a separate coating application. It is therefore evident that for such a product it is important to distinguish clearly between dewatering efficiency and the ability of the coating to protect an article in a corrosive environment.
