Prosol chemicals pvt. Ltd. Manufactures a unique economical water-based rust preventive.It provides short term rust protection to all ferrous metals. Hydro rp water-based rust preventive chemical guarantees protection for various steel and cast iron components up to 8 weeks in in- doors. It is ideal during inter machining storage of components. Hydro rp is to be diluted in water at 1:5 to 1:10 ratio and hence works out to be economical. This water-based rust preventive does not contain any petroleum based oils and does form thick oil films on the surface of the components, thus eliminating the need for subsequent cleaning/degreasing prior to other operations, which is the major problem in oil based rust preventives. It can also be used as a passivating chemical. Hydro rp water-based rust preventive can be applied to components by dip application or by spray [especially in industrial washing machines or conveyorised washing systems].
