CorroPipe II PW Ultra
The Ultimate Lining for Potable Water Pipelines
A 100%-solids, instant-setting, rigid polyurethane for potable water use. Introduced in 2008, this next generation product features industry-leading performance characteristics: in terms of both initial adhesion and adhesion retention over time, there is no equal. Low water absorption and perm rating are other features. Resistance to undercutting exceeds all other products on the market and impact resistance is double that normally expected from rigid polyurethanes. CorroPipe II PW Ultra has application characteristics identical to Madison’s original CorroPipe PW, which has been in regular use since the 1980’s. Format is 1:1 plural component, instant setting. PW Ultra cures to form a tough, durable, resilient monolithic film that will not impart any taste to the contents of the pipe.
Approvals and Listings
CorroPipe II PW Ultra is a two-component, 1:1 ratio, quick-setting polyurethane. It can be spray applied to any thickness in a single coat at any ambient temperature.
CorroPipe II PW Ultra (AM) is a modified version of this product that contains MicroSpear, an EPA-registered anti-microbial agent. While the coating itself is naturally resistant to bacterial attack, MicroSpear resists the growth of microbial colonization on the surface of the coating (a health concern in many applications) and minimizes the risk of MIC (Microbially Induced Corrosion).
CorroPipe II PW (CM) is a version of this product containing NanoShield, an additive consisting of microscopic spheres of real ceramic that enhance the abrasion and impact resistance of the finished product without detracting from other physical Properties.
AM and CM additives can be specified together in your special version of CorroPipe II PW Ultra where service conditions require. Both are suitable for potable water use.
