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.

NEWS ALERT: VpCI®-372 Peelable Coating Protects Against Rust and Scratches

December 29, 2023

Do you ever wish you could apply corrosion protection to a metal surface for just a few days, weeks, or months and peel it off when the protection was no longer needed? Cortec® helps you do that with VpCI®-372 peelable coating.

VpCI®-372 Peelable Coating

VpCI®-372 is a water-based corrosion inhibiting coating that can be applied directly to metal for protection in sheltered conditions. It also serves as a light barrier against physical abrasion. At the end of the protection period, VpCI®-372 can be peeled off by hand and discarded as solid waste, revealing the protected surface below. It offers excellent UV resistance and can be matched to some custom colors. VpCI®-372 has a low VOC of 0.2 lbs/gal (24 g/L) and can be applied by spray, dip, brush, or roll.

The special characteristics of VpCI®-372 allow it to have a variety of creative uses. Some ideas are as follows:

  • Temporary protection of metal parts during shipment
  • Storage of aluminum boats and other large equipment
  • Masking of parts during large painting jobs
  • Protection of non-porous surfaces (e.g., windows and doors) from scratches and nicks on the construction site

An extra thick version, VpCI®-372E, is available for use on dynamic profiles such as splines, threads, or machined areas.

If you have a metal surface that needs temporary protection against corrosion and abrasion, and you want to be able to remove that protection at any time, consider using VpCI®-372 for the job. Contact Cortec® for more information and to discuss your specific temporary rust prevention needs.

NEWS ALERT: How to Avoid Coating Adhesion Problems on Specialty Substrates

You’ve coated your metal surface with a Cortec® direct-to-metal (DTM) coating. You relax in the confidence of good corrosion protection. Then, a few weeks later, you see the coating peeling off, compromising the protection you thought you had. What went wrong? The problem may be poor adhesion on a specialty metal substrate. The solution? Start with VpCI®-373 Wash Primer.

coating adhesion problems

Adhesion Challenges on Specialty Substrates

While most Cortec® Coatings can be applied DTM on carbon steel surfaces, some metals such as aluminum, galvanized steel, stainless steel, and other plated surfaces are difficult for most paints and coatings to adhere to. If adhesion fails, the coating fails, making proper surface prep vital. Common methods for improving adhesion on galvanized steel include acid etching or the use of lead/zinc/chromate primers. Chromate pretreatment and/or conversion coatings can be used on unpainted aluminum. However, Cortec® prefers the worker-friendliness of applying a water-based wash primer.

Water-Based Corrosion Inhibiting Wash Primer

VpCI®-373 is a fast drying, water-based acrylic wash primer that provides phenomenal adhesion on tough-to-adhere-to surfaces including aluminum, galvanized steel, and stainless steel. It offers multi-metal protection with a complex mixture of corrosion inhibitors, making it a competitive alternative to industrial grade solvent borne systems and/or those with heavy metals. VpCI®-373 should be applied at 0.5-1.0 mils (12.5-25.0 µm) DFT, allowed to cure for 72 hours, and sanded before applying a topcoat of choice.

Make Your Coating ‘Stick’ to Metal!

Next time you paint a specialty metal substrate, make sure you get the coating to “stick” by applying a base primer of VpCI®-373 for good adhesion. Contact Cortec® for further support when painting galvanized steel and aluminum surfaces.

NEWS ALERT: Biobased Alternatives to Methylene Chloride Paint Strippers

This year, the EPA proposed banning most uses of methylene chloride, mentioning the availability of alternative products that do not include this extremely dangerous chemical. In light of tightening regulations and the obvious hazards of methylene chloride (a chemical often used in industrial paint strippers) Cortec® invites those seeking alternative products to consider trying EcoLine® 4320 or 4330 for their next paint removal task.

paint strippers

Eliminating Methylene Chloride and NMP

Cortec® introduced EcoLine® 4320 and 4330 five years ago, as more retailers were pulling paint strippers containing methylene chloride and N-methylpyrrolidone (NMP) off the shelf. EcoLine® 4320 and 4330 do not contain either of these substances. However, in a salute to “green” chemistry, they incorporate renewable raw material, which has allowed them to earn the USDA Certified Biobased Product label as products that contain 50% USDA certified biobased content.*

Removing Paint from Metal and Concrete

EcoLine® 4320 and 4330 can be used on metal, cementitious, and masonry surfaces such as tanks, pipes, equipment, floors, and stairways. EcoLine® 4320 is a liquid version that can be applied via dip tank; EcoLine® 4330 is a gel that can be brushed or rolled onto coated surfaces. In most cases, EcoLine® 4320/4330 will soften the coating enough to remove it in 15-30 minutes, although this can vary depending on the number of layers and age of the coating. Corrosion inhibitors provide the added benefit of protection against flash rust on metals during the stripping process.

Get the Job Done with Biobased Alternatives

Regulations are tightening, but reality is also setting in about the serious health risks of methylene chloride. EcoLine® 4320 and 4330 are examples of chemistry advancements that eliminate these chemicals while helping industries get the job done and introducing raw materials from renewable resources. Contact Cortec® to learn more about these USDA Certified Biobased Product alternatives for paint removal.

NEWS ALERT: Get Your Fleet Ready for Winter with These Undercarriage Coatings!

Winter brings snow and ice, prompting DOTs (departments of transportation) to get deicers out on the road to keep travel safe. As a result, plenty of deicing salts splash up on cars, trucks, and buses, leading to corrosion if not washed off quickly and thoroughly enough. Unfortunately, it is much harder, but not less important, to clean the vehicle underbody. Applying Cortec® underbody coatings before winter sets in is therefore a great corrosion prevention strategy for vehicle and fleet owners.

cortec underbody coatings

Anticorrosion Underbody Coatings

CorrBarrier™ Primer is a fast-drying water-based one-coat system suited for corrosion protection in the underbody/under-hood market. Although called a primer, it can serve as a standalone coating for protection of vehicle frames and undercarriages. It has a low VOC of 0.2 lbs/gal (24 g/L) and has a recommended DFT (dry film thickness) of 2.0-3.0 mils (50-75 µm). It is an ideal choice for those concerned about worker exposure to solvents and high VOCs. VpCI®-398 is a similar, yet heavier duty, solvent-based underbody coating. It can be applied more thickly at 4.0-5.0 mils (100-125 µm) DFT for stronger protection. Both coatings remain flexible with good chip resistance in case of gravel, salt, and other road particles hitting the coating.

Winterize Your Fleet Now

It can be difficult to plan ahead, but with winter fleet maintenance, the payoff can be huge. Coating undercarriages of cars, trucks, buses, and snowplows now will help them weather the winter better, resist corrosion, and ultimately last longer. Multiply the value of one truck’s extended service life by the scores or hundreds of vehicles in the fleet, and the ROI is significant. Contact Cortec® to learn more about coating your vehicle underbody to be ready for winter!

News Alert: New Demo Video: VpCI®-426 Rust Removal Time-Lapse!

Rust removal with VpCI-426We are pleased to release another Cortec® demo video! The latest addition to our YouTube channel shows “How to Remove Rust in Less Than 1 Hour with VpCI®-426!” Fortunately for viewers, it takes less than a minute of time to watch this time-lapse and see what happens to a rusty piece of metal placed in Cortec’s VpCI®– 426 rust removal liquid.

The time-lapse format of this video gives an interesting perspective on Cortec® rust removal, allowing viewers to see pieces of rust fall off the metal in seemingly rapid succession. This accelerated view is a great way to grab the attention of your clients and social media network and introduce them to a rust removal solution that they can use in their own industrial settings.

As noted in the video description, actual rust removal speed will vary depending on the degree of rust, the concentration of VpCI®-426, and the temperature of the solution. For example, it will take longer to remove rust on a heavily rusted surface than a lightly rusted one. A stronger concentration of VpCI®-426 will remove rust more quickly than a higher dilution; however, diluting VpCI®-426 may provide enough rust removal power in certain cases while allowing the product to stretch farther for greater economy. Increasing the temperature of VpCI®-426 and agitating it within the container can also accelerate rust removal.

Whichever direction your rust concerns take you, this demo video is a fun place to start when looking for a simple rust removal answer for both you and your clients. Watch the rust removal timelapse here!

NEWS ALERT: A Little Preventative Maintenance Goes a Long Way: Mining and Ready-Mix Trucks

Heavy equipment is essential to the mining and construction industries. However, work crews face two major upkeep challenges: (1) Harsh environments lead to corrosion and shortened service life and (2) Spilled cement and asphalt are difficult to remove once hardened. Cortec® is seeking to help crews minimize these problems with three handy preventative maintenance coatings.

Preventative Maintenance for Mining

Option 1: Annual Preventative Maintenance

VpCI®-391 is a water-based coating that can be sprayed directly over bare or painted metal. It leaves behind an inconspicuous non-tacky coating that inhibits corrosion and thus extends the service life of the equipment. Since VpCI®-391 is technically a removable coating that can wear off over time, it should typically be reapplied once a year during annual preventative maintenance activities. Heavy equipment owners/users who have applied VpCI®-391 in this way have seen a significant improvement in service life in harsh conditions.

Option 2: Long-Term Preventative Maintenance

For workers who want to get more time out of their “paint job,” EcoShield® VpCI®-386 serves as an outstanding permanent water-based corrosion inhibitor coating. It can be applied as a very thin clear coat over bare metal and painted surfaces, or, if desired, tinted to match the truck’s color theme. It can slow down the corrosion process for multiple years without reapplication.

Option 3: Corrosion Protection + Easier Cleaning

MCI® Creteskin® is a great option for ready-mix or asphalt trucks that are incredibly difficult to clean after concrete or asphalt residues dry on the surface. Spraying a coating of MCI® Creteskin® on the equipment before it is used leaves behind a coating that cures to a slightly waxy finish and prevents adhesion of cementitious materials. This makes it easier to clean hardened materials with high pressure water instead of abrasive blasting or acid removal. It also inhibits corrosion. Touchup can be done as needed to areas of the coating that wear away after normal use. Although it takes more initial thought and effort to apply a protective coating before the problem happens, doing so pays off in the long run by helping equipment last longer and making it easier to maintain. Take some time today to consider what situations your equipment will be up against and contact Cortec® for help picking the best coating for your application.

NEWS ALERT: How to Select the Best Cortec® Rust Preventative for Your Needs

Just because one Cortec® product is a great rust preventative (RP) does not mean that it is the best choice for every application. In fact, Cortec® offers a variety of rust preventatives with specific characteristics that make some Cortec® RPs ideal for one application and other Cortec® RPs ideal for another. Viewing these flagship RPs through the accompanying selection grids can help users decide which one they prefer for a specific situation.

Storage or Shipping Environment

The most important factor in making your decision is determining the level of protection needed. Metal parts that sit outdoors need more robust protection than those that experience only slight humidity changes indoors. Metals stored in sheltered outdoor conditions need more protection than those indoors but can take advantage of robust RPs that could otherwise be washed off in the rain.

Product Carrier

The product carrier is another important characteristic that factors into the choice of an RP. Some users want a more sustainable, worker-friendly product that is water-based or biobased, while other companies have specs that have been around for decades and still call for solvent-based RPs.

Film Type

The film type can affect handling and appearance of the protected parts. Thin, dry RPs are very inconspicuous and great for tight tolerances. Oily RPs can be good for rotating components. Thick RPs may be better where heavy-duty protection is needed.

Removal

Those responsible for choosing an RP should also consider what kind of cleaning scenario end users want to see. If power washing is okay, a thicker RP can be used. Other RPs only require light washing or no removal at all.

Next time you choose an RP, be sure to look at your options through the grids at left for the most satisfactory experience. Need more help or other options? Contact Cortec® today to discuss your specific rust preventative

NEWS ALERT: Why Use Cortec® VpCI® Primers?

A primer is a great addition to any coatings system wherever time and budgets allow. When it comes to painting metal, Cortec® VpCI® primers are a great choice for coating adhesion and corrosion protection.

Why Use Cortec® VpCI® Primers?

VpCI® Primers and Adhesion

One of the main purposes of a primer is to get good adhesion so the final topcoat sticks firmly to the surface below. While most Cortec® Coatings can be applied direct-to-metal, applying one or two coats of primer first makes the system even stronger. VpCI®-375 is a fast-drying thixotropic coating that can be used as a base layer on carbon steel and copper. Other metals such as aluminum, stainless steel, and galvanized steel are more difficult for coatings to adhere to and should be primed with VpCI®-373 wash primer to help subsequent primer/topcoat layers stick to the metal.

VpCI® Primers and Corrosion Protection

Another important reason for using VpCI® primers is corrosion protection. While other metal primers could theoretically be used with a VpCI® topcoat, it would not allow the VpCI® corrosion inhibitors to have direct access to the metal surface. Using a VpCI® primer gets Cortec® corrosion inhibitors as close to the metal surface as possible and is therefore an ideal foundation to a Cortec® Coatings system.

Get VpCI® Directly to the Surface

Cortec® Coatings offer the flexibility of choosing the convenience of a one-coat water-based system or the enhanced protection of a multi-coat VpCI® primer/topcoat system. Whenever time and budget allow, go for the best protection by getting VpCI® primer directly to the surface. Contact Cortec® for specific project recommendations.
