PRESS RELEASE: Cortec’s Toughest Removable Coating for the Most Corrosive Conditions

March 22, 2024

removable coatingFor more than four decades, VpCI®-368 has been Cortec’s toughest removable coating for corrosion protection on metal parts. Today, it continues to be widely used in preservation and shipping applications. Anyone interested in taking advantage of this rust preventative standby for corrosive conditions can rise to the occasion by understanding what the removable coating is like and how it can be used.

Temporary Waxlike Coating

VpCI®-368 is a solvent-based temporary waxlike coating that provides protection in harsh, unsheltered environments. It dries quickly to a slightly brown finish and protects at 2-3 mils (50-75 µm) DFT (dry film thickness). It can be removed with an alkaline cleaner such as VpCI®-414 or another flash rust inhibiting cleaner from the VpCI®-41x Series.

Layup of Stationary Surfaces

VpCI®-368 can be applied to new equipment in transit or use equipment that needs to be laid up, for applications such as rig stacking or other large preservation projects. Whereas VpCI®– 369 is a go-to for corrosion protection on moving parts during layup, VpCI®-368 is often the default coating for stationary surfaces.

Flange Face Protection

Another common use for VpCI®-368 is protection of valve or pipe flanges in extreme environments. By applying a temporary coating, manufacturers or inventory managers can protect the sensitive flange face from corrosion that could otherwise delay startup especially in the case of gramophone raised faces, which may need to be resurfaced if damaged.

Protection of Wind Components

One manufacturer of wind turbine shafts, rings, and hubs has made use of VpCI®-368 D to protect their most sensitive metal surfaces during shipping and storage. The components are exported around the world and stored indoors or outdoors for two to five years. Past corrosion problems inspired the manufacturer to explore and adopt a Cortec® corrosion solution that consists of the following:

• Clean components with a dilution of VpCI®-415 and dry.
• Apply VpCI®-368 D by roller to designated areas.
• Shrink wrap components in VpCI®-126 HP UV Shrink Film or MilCorr® VpCI® Shrink Film (these offer UV resistance and extra corrosion protection for potential outdoor storage).
• Send VpCI®-414 along as part of the kit so the end user can remove VpCI®-368 D when needed.

Rise to the Occasion with Removable Coatings

In industry, many occasions arise for the use of a temporary rust preventative coating. When the harshest conditions exist, a removable coating such as VpCI®-368 is an excellent choice for interim corrosion protection during shipping and layup, whether for a one-time preservation project or as part of routine shipping procedures. Contact Cortec® to learn more about this and other removable coating options.

NEWS ALERT: These Anticorrosion Coatings Slow Down Aging on Heavy Equipment!

Heavy equipment is an integral part of everyday industry. It is also an expensive investment, making it critical for equipment owners to extend asset service life as long as possible. Where corrosion threatens to shorten that lifespan, Cortec® recommends several protective coatings to enhance preventative maintenance.

Why Does Heavy Equipment Age Early?

Heavy equipment is often used in harsh environments. Fertilizer loading at barge docks, coal moving at power plants, and material handling at sauerkraut factories are just some of the activities that can quickly age fork trucks and front-end loaders, causing paint to peel and surfaces to rust. Even manufacturers face the challenge of keeping equipment in like-new condition when it is shipped overseas and sitting outdoors in a distributor’s show yard for several months before resale.

Coating as Part of Routine Maintenance

Two Cortec® Coatings stand out as excellent options for delaying corrosion on heavy equipment. Both can be applied un-tinted over bare and painted metal surfaces or matched to a desired color scheme. Both are water-based and allow for easy cleanup. EcoShield® VpCI®-386 is a permanent coating that inhibits corrosion at a very thin DFT (dry film thickness) and has a VOC of 0.6 lbs/gal (72 g/L). VpCI®-391 is a removable coating that dries to a hazy non-tacky film and has a low VOC of 0.4 lbs/gal (48 g/L). The latter is a great option for shipping new equipment as well as for performing annual preventative maintenance, as it can inconspicuously be left on for extended periods or sprayed off with an alkaline cleaner. Two other helpful maintenance coatings are CorrVerter®, a water-based rust-converter primer that can be used for restoration on previously rusted surfaces, and VpCI®-369, an oil-based wet-film corrosion inhibitor good for moving parts.

Add a Layer of Protection to Assets

Some environments cause heavy equipment to age more quickly than others. Applying a Cortec® permanent or removable coating is a great addition to the normal maintenance routine, providing inconspicuous protection to painted and bare metal surfaces. Contact Cortec® for more tips on heavy equipment corrosion preventative maintenance.
