Poly Urea Coating Process – IT WORKS!

“You haven’t talked about the coating process lately. Any problems with the process we need to know about? I’ve heard that some of the processes are too time consuming to make any production levels feasible.”

Quik-Coating System

There are several competitive processes out in the market place that use a variety of resins and are applied with brushes or spray nozzles. Some use epoxy, others polyurethane and poly urea. Most formulations have taken a product developed for drinking water under NSF 61 and applied or misapplied it to the wastewater side of a building. We started with a resin formulation that was suitable for wastewater conditions and all the chemistry found in sewer first then built a delivery system around the material. While some of these formulations may work in sanitary sewers, they were developed for potable water. Potable water doesn’t usually contain all the chemicals that wastewater carries. The Quik-Coating Process developed and tested the resin to meet or exceed the demand of the resin carrying the wastewater to the sewerage system. There is a standard for the AIPPR process that pertains to sanitary sewers. This is a different standard than the standard used for the SIPP (sprayed in place pipe) process that addresses the potable water market. If you are applying a standard designed for other processes into a sanitary sewer and you have a failure, are you providing your clients with the best processes available. We have different standards for lining processes used for potable water while the CIPP process addresses sanitary sewers and we need to follow the same separations for wastewater coating to potable water coating processes.

Successes have been many as well as fails. We’ve learned that glass pipe doesn’t accept the coating process as it won’t stick. We never tested glass lined pipe and didn’t anticipate that we’d ever run into it, but we did. After many tests and tracking down the pipe, we found out that this type of pipe isn’t designed for coating processes. We did learn that with the slight expansion of the poly urea product, tracking isn’t a problem as it is with epoxy systems or trying to apply CIPP to laterals with pre-cut holes for the tie-ins. Tracking of water between the host pipe and the liner or coating isn’t a good condition as you haven’t solved a problem. You still have pipe deterioration and will have an eventual failure as opposed to the Quik-Coating poly urea system.

Quik-Coated PVC

After over a year into the first application, we’ve tested the original application and found it standing up to the DWV demands over the past 15 months. Our testing of application to cast iron (steel) pipe, clay, ABS, and PVC has proven a clear product that exceeds the others in the industry. We also learned that the hardness we’ve achieved with the product have resisted the typical debris that end up in the drains.
