Claremore, Oklahoma -- Witt Lining Systems is offering a new polyurethane material, Witt TPU, for flexible corrosion resistant liners in tanks, pits, sumps and trenches, especially in applications where PVC is not an acceptable choice.
"We've been looking at these materials for a while and have finally found a formulation that we are positive will provide excellent corrosion resistance and service life in applications not well suited for our PVC materials," said Andrew Hotchkies, president of Claremore, Oklahoma-based Witt Lining Systems, in an announcement.
WITT TPU is primarily designed for containment of fuel, oils, hydrocarbons and fatty acids, with good physical properties - it is very durable and puncture resistant. The cold temperature range of WITT TPU also exceeds that of Witt's PVC formulations, and it is FDA compliant as well as capable of being made with an NSF-61 rating.
The lining producer sees a good market for this product in situations where concrete coatings have failed due to penetration of products into a concrete containment area or pit.
Hotchkies commented, "Concrete is very porous and once concrete has been saturated with oil or fats it is timely and expensive to make that concrete suitable for a new coating. Because our flexible liners aren't bonded to the concrete, we can be installed right over top of concrete without great concern of the condition of the substrate. This reduces an incredible amount of installation time and saves our customers money and maintenance down time."
