Anti-corrosion specialist Cortec offers a water-based removable coating to protect heavy equipment, machinery, vehicles, piping, and structural steel in storage and transit. The VpCI-391 water-based coating offers corrosion protection for indoor and outdoor applications and dries to a thin, clear film which is virtually unnoticeable. VpCI-391 can be used to protect unpainted and painted surfaces, as well as to prevent dissimilar metal corrosion.

As a water-based coating, VpCI-391 is much easier to use and clean up than solvent-based systems. It can be easily removed from equipment or structures using alkaline cleaners. This, however, is not always necessary because of the coating’s clear non-tacky appearance.

According to Cortec, these characteristics make VpCI-391 an excellent alternative to applying traditional thick, heavy, waxy or greasy products like COSMOLINE or Tectyl, which are messy to use, difficult to remove, and do not leave a clean appearance.

The product is used in some of the toughest climates in the world, including industrial and offshore environments. VpCI-391 is also gaining popularity with manufacturers who have found it to be an excellent option for transit protection of newly made equipment. Before shipment, manufacturers can spray VpCI-391 over door handles, hydraulic connections, wheel hubs, chassis, or anywhere corrosion might become a problem. VpCI-391 has been used to safely transport fire trucks, heavy equipment, and complex oil rig equipment, as well as to protect pipes and equipment from deterioration in outdoor storage yards, Cortec says.

VpCI-391 is a single component system with no mixing required. It can be applied via spray, brush, roll, or dip. VOCs are less than 0.5 pounds per gallon (48 g/L). The coating goes on white and dries clear, or it can be tinted to a specific colour if desired. VpCI-391 does not harm plastic, so overspray on plastic components is not a concern.
