Hard chrome plating solutions are very aggressive at the upper and lower solution levels of the tank. As the solution evaporates, the concentration of chrome increases. Concentrated chrome vapor then condensates in the freeboard area and attacks traditional PVC liners. Witt Lining Systems innovated the solution of adding a skirt of either PVC liner or LFP CrossFilm™.
An extra layer of material that protects the liner from the corrosive chrome condensate. Skirts extend the service life of a tank liner leading to lower operating costs.
A skirt is a secondary layer of material that covers this upper and lower solution level that protects the main PVC liner from chemical exposure. A skirt made from PVC will act as a sacrificial piece of material but it will degrade over time and eventually expose the main liner to chemical attack. A skirt made from LFP CrossFilmTM is chemically inert. LFP skirts don't break down over time and they eliminate any exposure of the PVC liner in this interface area giving the tank liner its full service life.
Couple the LFP CrossFilmTM skirt with the unmatched service life of a KorosealPVC liner and you have the longest lasting drop in liner available for hard chrome service. This longer service life means the associated time and costs of changing a liner out are fewer and provides a lower operating cost versus liners with no skirts.

Since 1972 we have been the industry leader in providing flexible PVC corrosion resistant liners. Flexible liners are a cost effective alternative to bonded Linings and coatings. Flexible PVC liners are used in plating tanks, chemical tanks, storage tanks, waste water treatment pits, secondary containment, cooling towers, pits, sumps, solar heated water storage tanks, or anywhere liquid containment or corrosion protection is desired.
Industries served include metal finishing, plating, anodizing, aerospace, oil and gas, mining, municipal water treatment, and food and agriculture. Witt offers a variety of materials such as Koroseal®, Spectra Blue® and Exceline®. Witt Lining Systems also offers alternatives to PVC, custom fabricating Teflon® , Kynar® PVDF , and XR-5® liners. Wiitt offers a variety of liner grades and thicknesses to suit your lining need. Links
