With an unparalleled track record of performance, Koroseal® Protective Lining has been the trusted name in corrosion resistant lining for over 60 years. Recently a new material has entered the market with claims that the product is the same or better. However, there is no concrete proof to substantiate these claims.
SUR/FIN 2016 in Las Vegas is a wrap. Naturally, we were proud to be on display showing off our drop in tank liners and in particular our Koroseal® PVC liners with an LFP CrossFilm™ skirt for added service life in hard chrome plating.
Our PVC drop in liners are a great solution for secondary containment problems. Flexible PVC liners are fast to install, require minimum surface preparation, and probably most important, can bridge cracks in concrete that would cause coatings to fail.
Hard chrome plating solutions are notorious for breaking down tank liners at the area where solution and oxygen interact. This is because as the solution evaporates the fumes condensate back on the liner. That condensate is now at a concentration of chrome beyond which PVC can handle. This causes the liner to break down at this area while the rest of the liner that is under solution still has years of service life left.
Just as many competitive products have a wide range in quality levels, flexible PVC liners are no different. The critical component used in producing flexible vinyls are specialized chemicals called plasticizers. There are countless varieties of plasticizers that can make vinyl flexible but very few offer the attributes needed for the vinyl used in the drop-in liner industry. It is safe to assume that the plasticizers used in producing garden hoses, blood bags, food packaging, car interiors, and children’s toys offer different characteristics then the plasticizers in our liner materials and they need to be selected accordingly.
