Water-Soluble Volatile Corrosion Inhibitor “VERZONE WA-DS” ｜ Rust Prevention for Hydrostatic Testing

High-concentration water-soluble volatile corrosion inhibitor for hydrostatic test water. Protects enclosed and complex structures, such as heat exchangers and piping, from rust formation.
VERZONE WA-DS is a powerful water-soluble anti-rust agent designed for hydrostatic testing of plant equipment. Formulated with vapor-phase corrosion inhibitors (VCI), it protects not only the surfaces in direct contact with test water but also enclosed internal areas where residual moisture often remains after testing.
Particularly effective for complex structures such as heat exchangers and piping systems, VERZONE WA-DS ensures thorough and reliable rust prevention. Its high concentration enables effective performance at low dosage, improving cost efficiency and reducing environmental load.
Available in Thailand from DAIWA FINE CHEMICALS (THAILAND) CO., LTD., it provides an easy and effective solution for equipment preservation and maintenance.
