VERZONE WA-DS is a highly concentrated, water-soluble volatile corrosion inhibitor ideal for hydraulic tests of tanks and boilers, providing comprehensive rust prevention in both liquid and gas phases due to its powerful evaporative properties. This pale yellow, water-soluble, weakly alkaline liquid has a specific gravity of approximately 1.045 at 25℃ and is non-flammable. Used at a 5-10% concentration in water, it effectively protects steel. Technical half-immersion tests demonstrate its superior ability to prevent rust in both submerged and vapor areas, a critical advantage over conventional non-vaporizable inhibitors that fail to protect the gas phase.
