Vapor-Tek’s original product, Vaporol, is a Volatile Corrosion Inhibitor (VCI), also known as a Vapour Phase Inhibitor or VPI.  An extremely versatile and popular product, it allows manufacturers to protect items that would be difficult or impossible to coat in a contact corrosion inhibitor like Steelgard due to complex machinery or inaccessible areas in pumps, tanks and pipework.

Like most VCIs, Vaporol is oil-based.  For the majority applications this is fine, often desirable, as it is compatible with most fuels and lubricants so can be safely used in engines, gearboxes etc. and does not need cleaning off or removing once the residual oil has been drained out.  It can even be added to oil to keep classic cars and motorbikes protected between occasional trips out.

In some circumstances, however, an oil-based inhibitor causes as many problems as it solves.  Where a product is intended to be filled with water, customers do not want an oily residue when it is commissioned.  If a component needs to be stripped back to bare metal in order to add a coating or when assembling the finished product, the need to use a solvent wash to remove every trace of Steelgard can be offputting.

Aquavap is our response to these issues.  A complex, concentrated blend of corrosion inhibitors in an aqueous base, it contains no oil, solvents or other harmful materials. In an enclosed space the corrosion inhibiting vapours build up in exactly the same way as Vaporol, protecting every nook and cranny from rusting.  It can be sprayed , fogged or flooded into packing cases, tanks, pressure vessels, tubing, metal sections, etc which can be capped or wrapped to retain the vapours, ensuring they remain pristine even during long-term storage or lengthy shipping times.

Aquavap has an additional superpower – it also acts as a contact corrosion inhibitor whereby everywhere it is physically applied – by dip, brush or spray, then dried, is left with an almost indetectable coating which will keep corrosion at bay and also slowly release VCI vapours which, provided the components are enclosed in a box or bag, will continue to protect any areas which were not fully coated.

In most cases Aquavap does not need removing when parts are put into service however, when removal is required, it simply washes off with water.  No solvents or detergents are needed as it is completely water soluble.

During testing of pumps, valves, hydraulic systems, pressure vessels, tanks, heat exchangers, etc. residual water can lead to corrosion where it lies and the humidity which results can cause rust to start out of sight.  Using Aquavap as supplied, or diluted with water, means the combined contact and vapour action will prevent corrosion both below the level of the (unavoidably) retained liquid and in the vapour space above – no need to dry out.

Call us if you would like to chat about whether Aquavap is the most suitable corrosion inhibitor for your application – we are always happy to advise.
