DESCRIPTION 

VpCI-609 is a water-soluble Vapor phase Corrosion Inhibitor (VpCI ®) powder for wet or dry corrosion protection of ferrous metals and aluminum. VpCI®-609 is also available as VpCI®-609 S (with silica) and VpCI®-609 W (ready-to-use liquid version).

FEATURES 

• VpCI-609 is accepted by Cefas as an offshore chemical. Registered under OCNS number 25717 allowing use at 5,000 ppm 

• Protects in liquid phase, vapor phase, and at the air-water interface 

• Creates a molecular corrosion inhibiting layer on metal surface 

• Provides up to 24 months of continuous protection 

• Does not contain nitrites, phosphates, or heavy metals 

• Passes Vapor Inhibiting Ability Test (NACE Standard TM0208-2008) before and after Exhaustion Test (MIL-STD-3010C) 

ADVANTAGES 

• Vapor-phase inhibiting action protects inaccessible and recessed surfaces 

• If the VpCI® layer is disturbed by moisture or the opening of an enclosed space, the layer is replenished by continuous vapor redeposition 

• Prevents future corrosion of precoated and painted surfaces 

• VpCI® layer typically does not need to be removed prior to processing or use 

• If required, powder is easily removed by air gun or water flush 

• Does not increase alkalinity 

• Provides economical protection for very large applications 

• Available in ready-to-use liquid form for convenience in hydrostatic testing and preservation applications • Offers the best ecological footprint in comparison with competitive VCI powders 

• One of the most powerful, fast-acting water-soluble Vapor phase Corrosion Inhibiting molecules used worldwide for corrosion remediation and control

TYPICAL USES 

• Tubular structures, pipes, and vessels 

• Voids, cavities, and tanks 

• Internal surfaces of compressors, turbines, engines, tanks, boilers, heat exchangers 

• Steam condensate lines, closed circuit heating, and cooling systems 

• Equipment during and after hydrostatic testing 

• Parts, components, and completed assemblies during shipping and storage 

• Additive to shot-blasting media, wet blasting 

• Additive to standing water

METHOD OF APPLICATION 

Apply VpCI-609 in dry form by dusting, fogging, or sprinkling. (Fogging is easily achieved by using a low pressure air hose and sandblast cup. Large conventional sandblasting systems can also be used). For wet applications using VpCI®-609/609 S Powder, pre-mix with water to dissolve the powder prior to application. For VpCI®-609 W, dilute to recommended concentration and mix well prior to application. Apply VpCI®-609 in aqueous form by spray, flush, or immersion. After application simply cover and close or seal the interior cavity or void. 

DOSAGE 

Product                                                 Dosage* 

VpCI®-609/609S              0.3-0.5 oz/ft3 (300-500 g/m3) 

VpCI®-609                               W 4-8% (when hydrotesting)

 *These are general dosing guidelines and may not be suitable for every application. Please contact Cortec® Technical Service for specific dosing information. 

METHOD OF REMOVAL

When required, VpCI®-609/609S in powder form can be easily removed by using a low pressure air gun or a water rinse. Typically, if applied in aqueous form, the product does not require removal. If necessary, a simple water rinse or flush will suffice.
