Permalok uses several options for our coatings and linings. The primary materials applied to Permalok products are:

Coal Tar Epoxy – A catalyzed, two-component lining that combines the corrosion-resistant characteristics of coal tar pitch with those of epoxy resin, resulting in a cured lining that will tolerate reasonable impact abrasion and flexing.

Bitumastic – Bitumastic is made from coal tars and blends of resins such as epoxy. A trade name often associated with long-term protection from water penetration, Bitumastic is an economical, heavy-duty material which protects piping subjected to water immersion.

Madison Chemical “Corropipe II” – Polyurethane coatings and linings are enhanced with an anti-microbial agent to protect pipes against microbiologically influenced corrosion (MIC, commonly known as hydrogen sulfide corrosion). Corropipe II protects against this type of corrosion by acting as a barrier between the corrosive elements (i.e. in wastewater systems) and the surface of the structure being protected. The anti-microbial agent in the coatings effectively reduces the number of bacteria in the environment, inhibiting the potential for MIC to occur. Corropipe II PW is NSF certified for potable water.

Power Lonestar “Powercrete®” – An epoxy based polymer concrete which protects the steel pipe under severe handling conditions. It is highly abrasion-resistant, and provides a smooth surface that allows for less drag resistance than standard concrete.
