Cortec® removable coatings have been used time and time again for mothballing and offshore layup projects around the globe. They meet an important need for interim protection of metal surfaces where other VpCI® Technologies may not be as well suited. Some of the common uses are as follows.
Parts that move and/or require lubrication, such as rotating or reciprocating equipment, can be protected with VpCI®-369, VpCI®-369 D (diluted), or its popular aerosol counterpart, CorShield® VpCI®-369. This leaves behind a wet film corrosion inhibitor on the metal surface.
VpCI®-368 is often used to apply a wax-like protective coating over static/stationary surfaces (painted or unpainted) of metal equipment around the layup site. It can be applied full strength (VpCI®-368), as a diluted version (VpCI®-368D), or in aerosol form (CorShield® VpCI®-368).
VpCI®-391 is a popular water-based coating for general protection of structural steel around the layup site. For example, it can be sprayed right over painted handrails and structural steel on offshore platforms for an extra layer of protection in harsh environments.
When layup is over, all three coatings can be removed with an alkaline cleaner such as VpCI®-414. However, sometimes, as in the case of VpCI®-391, this is not even necessary! Contact us to learn more about selecting the best removable coatings for your layup project:
