商品詳細(xì)
VpCI®-377 is a corrosion preventive liquid that meets tough anti-pollution 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. In many cases, VpCI®-377 does not always need to be removed, but if necessary, can be removed with conventional alkaline cleaners, such as Cortec VpCI®-414.
VpCI®-377 is also available in a cold weather version. VpCI®- 377 Winterized has a lower freezing point for the convenience of application and storage in cold temperataures.
*Contact Cortec® Technical Service for dilution recomendations.
