VCI powder is watersoluble, spayable volatile corrosion inhibiting powder designed for the corrosion protection of self-seal system (e.g. tubular structure and pipes) and metals in the enclosed space. SF/D-331 provides excellent volatility, migratory and absorbable performances, and forms a molecular protective layer on the metal surface, which can effectively protect metal against corrosion. It can be put in different sizes of bag.

Method of application:
Apply SF/-331 in dry form by spraying easily achieved to pipe or vessel, closed after application. by using air pressure, air hose or sandblast, large conventional sandblasting system or hand blast can also be used. For powder application, with average environmental condition, use 100g/m2, the dosage can be increased for more severe condition.

In wet form, apply water presser testing soluble and then remove water solution and close vessel after application. Also can dilute  solution to spraying, printing and dipping, and then seal packing. at the ambient temperature water solution ratio 1:0.5%, the dosage can be increased for more severe condition. To increase the metal surface wetness, to apply SF/TD-101 1.0% is recommended, the dosage is 1.0% weight of SF/D-331 powder.


Metal protected:
Carbon steel, steel alloy, stainless steel, aluminum and its alloy.
To move powder residues easily by air presser and water,
To move liquid form, no cleaning required, if necessary, simply rinsing or spraying with water.
