Corrosion Resistant Coil Coating (Blygold®)

BlygoldPoluAl is a metallic impregnated polyurethane coating specifically designed for application to aluminum finnedcopper tube

It is a thin (25 microns), flexible, UV and impact resistant coating that exhibits excellent adherence to aluminum surfaces. PoluAl protects the parent metal against a wide range of corrosive salts, acids, and other elements found in the atmosphere and provides protection superior to that of Cu/Cu coils. In addition to a superior ability to resist corrosion, the unique characteristics of PoluAl result in it having only a negligible effect on pressure drop, and heat transfer (k value) of the coated coil. The HVAC/R unit coated with PoluAl receives all the benefits of corrosion protection without losing operating efficiency.
