Witt Lining Systems products

Koroseal PVC has a long proven track record of superior performance and lining protection in a wide range of chemical applications. Its unique formulation provides high resistance to strong corrosives, alkalis and salts. With an upper operating temperature of 200OF, Koroseal is designed to handle the most aggressive applications. Koroseal is an excellent choice for process tanks and storage tanks. It is highly recommend for use in hard chrome plating solutions coupled with a Witt skirt and for any other chrome based solution. Koroseal`s high temperature range also makes it ideal for solar water storage tanks.

At its name implies, HP Koroseal takes standard Koroseal to the next level. With a slightly improved formulation HP Koroseal provides an added temperature range of up to 210OF and provides a longer service life in harsh conditions. Like standard Koroseal, HP Koroseal is recommended for process tanks and storage tanks and in applications where temperature ranges are high or chemical concentrations are very aggressive. HP Koroseal drop in liners are available in 3/16 in. gauge. Other gauges are available on a qualified quantity basis.

Exceline PVC is a premium PVC formulation that offers greater chemical resistance and higher temperature ranges than standard PVC. Exceline PVC has very high acid, alkali, and salt resistance and has a constant operating temperature of 180OF. Exceline PVC is an excellent choice for both low and high pH solutions particularly with high concentrations. Exceline PVC has been used with great results in plating tank, chemical process tank, storage tanks, and waste treatment applications. Exceline PVC is also used as a disposable type liner for Electroless Nickel plating to eliminate the need for chemical leaching of the tank. Exceline drop in liners are available in 20 mil, 60 mil, 3/32 in., 1/8 in., and 3/16 in. gauges.

Spectra Blue PVC is a proprietary formulation of PVC that has been exclusively developed by Witt Lining Systems. A lower cost material compared to our other formulations, Spectra Blue PVC provides excellent chemical resistance to most acids, alkalis and salts up to a constant operating temperature of 145OF. Spectra Blue PVC is an excellent choice in both primary and secondary containment applications. With added UV inhibitors, Spectra Blue PVC is designed for both indoor and outdoor uses.

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. This 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 or LFP CrossFilm.
