What can be done to keep the inside of electrical conduits from rusting while providing enough slip for electrical wires to pass through? Cortec® has provided the answer with the development of its new EcoShield® VpCI®-386 HT Slip Coating. This is yet another example of Cortec’s role as an innovator in corrosion control, creating exciting new products adapted to specific end user needs.

EcoShield® VpCI®-386 HT Slip Coating is a unique high-heat-resistant water-based DTM (direct-to-metal) coating that offers improved surface slip, excellent outdoor weathering, and thermal heat protection. It significantly retards the reaction of metal ionization and repels water, thus protecting against corrosive electrolytes and aggressive environments. This thixotropic coating resists sagging and running and is thermally stable when dried in ambient temperatures up to approximately 500 °F (260 °C), depending on color choice (Clear, Black, or Aluminum). EcoShield® VpCI®-386 HT Slip Coating offers extended protection in sheltered, unsheltered, indoor, or outdoor conditions and is UV resistant to resist cracking or chipping from prolonged exposure to sunlight.

Why Corrosion Protection for Electrical Conduits?
Corrosion protection is more critical in some environments than others. For example, electrical conduits are more vulnerable to corrosion when stored
outdoors than indoors, or when installed in a tropical, humid climate instead of a hot, dry one. Corrosion protection may be necessary in several phases of the piping life cycle.

1. Outdoor Storage: Manufacturers are often short on storage space, which can cause storage to overflow outdoors. If it rains and the internal coating has not fully cured, the inside of the conduits may flash rust. EcoShield® VpCI®-386 HT Slip Coating minimizes this problem.
2. Overseas Shipping and Storage: Manufacturers sometimes have to ship pipes and tubing overseas, where they may even be stored for six months longer before the customer is able to install them. Again, EcoShield® VpCI®-386 HT Slip Coating can help protect against internal corrosion.
3. Harsh Installation Environments: Industrial facilities must install electrical conduits in a variety of conditions, from dry indoor office spaces to corrosive offshore environments. EcoShield® VpCI®-386 HT Slip Coating can help delay or reduce the corrosion process inside the tubing so
the electrical conduits last longer.

Why a High-Temp Slip Coating?
Slip coatings are very important for electrical conduits because they reduce the coefficient of friction on the inside of the pipes. This makes it easier to push electrical wiring through the tubes when they are installed. By combining a slip coating with Cortec® VpCI® corrosion inhibitors, EcoShield® VpCI®-386 HT Slip Coating helps electrical conduit manufacturers and users tackle two challenges at once. Another important consideration is the temperature required during coating application. Many tube makers must briefly expose piping to extreme heat during the manufacturing process (e.g., to cure coatings). EcoShield® VpCI®-386 HT Slip Coating is therefore designed to withstand high temperatures so it will not be destroyed.

Get Ready to Coat the Conduit!
It can be challenging to protect pipe internals from corrosion, but Cortec® has made it possible with a new Micro-Corrosion Inhibiting Coating designed for this specialty application. By using EcoShield® VpCI®-386 HT Slip Coating, manufacturers can protect against flash corrosion during storage and shipment, and end users can help electrical conduits last longer even after pipes are installed in corrosive environments.

VpCI^®-277, a ready-touse dry film rust preventative especially designed for preserving metals during storage and transportation. VpCI^®-277 combines film-forming additives with Vapor phase Corrosion Inhibitors to provide excellent multi-metal corrosion protection. It is ideal for robotic assembly of precision components requiring tight tolerances and helps maintain a clean preservation process through absence of oily residue without containing chlorinated compounds, chromates, or nitrites. After major automotive manufacturer used Cortec’s VpCI^® products to protect parts during temporary storage and overseas shipping, they were very pleased with the protection achieved by applying a tenacious VpCI^® film to the metal parts. However, they needed a rust preventative with a drier film and a low VOC that would also meet their solvent-based specification. Cortec^® R&D solved the problem by developing VpCI^®-277, a rust preventative containing a biobased corrosion inhibitor in a non-flammable, low VOC solvent carrier.

VpCI^®-277 can provide corrosion protection for up to two years of indoor storage or during domestic or international shipments when combined with VpCI^® packaging materials. The product leaves a dry, non-tacky, virtually undetectable film on the metal surface.

The use of rust preventatives to preserve metals during storage and transportation has traditionally been a hazardous and messy process in which greasy rust preventatives must be applied and removed several times. This is because metal work-pieces risk flash corrosion as they frequently sit in temporary storage awaiting the next step in the manufacturing or assembly process.

Applying a rust preventative protects the parts but often requires an additional step of cleaning before the components can go through the next phase of the process. Cortec’s innovative products are able to streamline processes for more efficient manufacturing, assembly, storage, or shipping. The goal is to achieve quality protection while eliminating steps, improving tact time, reducing the use of additional materials and cost.

VpCI®-277, can be applied by spray or dip and left on metal parts during further processing or shipment. It does not require removal by the end user because the undetectable film does not interfere with use of the product in tight tolerances. This is significant as it eliminates the extra step of cleaning, significantly cutting down on labor time and expenses by enabling a more streamlined tooling, storage, and shipment process.
Development of this rust preventative designed for tight tolerances is a nice example of how Cortec^® is able to adapt technology to special end-user needs in order to provide the optimal product characteristics for a specific application.

VpCI^®-277 conforms to ASTM D1748 (Humidity), ASTM D1735 (Water Fog), MIL-C-83993 (Water Displacement), and NACE RP0487-2000 (Selection of Rust Preventives) standard test methods.
