RPI-3000A is specially designed to inhibit scale formation in RO systems (polyamide, celluloseacetate and polyether membranes with an anionically charged surface).RPI-3000A has high cation dispersing properties.RPI-3000A is an excellent crystal growth inhibitor for calcium sulphate, calcium carbonate and calcium fluoride. A further advantage is the superior stabilization of iron oxide suspension in water in addition to the inhibition of the oxidation properties of salts like manganese (IV) oxide.
