Cortec VpCI®-377 Water-based Concentrate

Product Description

VpCI®-377 is a water-based concentrate designed as a complete replacement for oil-based preventives for indoor protection of equipment and components. VpCI®-377 is a corrosion preventive liquid that meets tough antipollution requirements. The wide dilution range with water (0.5-20%)* allows flexibility to customize the length of protection required and the applied cost per square foot (or m2). VpCI®-377 forms a solution in water and is applied to metal surfaces by spraying or dipping. VpCI®-377 does not need to be removed, but if necessary, can be removed with conventional alkaline cleaners, such as Cortec’s VpCI®-410 series. VpCI®-377 is also available in a cold weather version. VpCI®-377 Winterized has a lower freeing point for the convenience of application and storage in cold temperatures.
