EPO ROVAL Cold Galvanizing Compound

Better heat resistance and solvent resistance.
Equivalent anti-corrosion performance to hot-dip galvanizing.
Achieve high-quality coating system by using together with top coat.

EPO ROVAL Cold Galvanizing Compound contains 96% pure zinc powder in its dry film.
As it’s prepackaged in single packs, it doesn’t require mixing, or the additional use of a primer. It’s easy to use and can be applied directly to steel and galvanized surfaces.
EPO ROVAL combines the ease of painting with the excellent corrosion resistance of hot-dip galvanizing. Since EPO ROVAL is simply applied in standard temperatures, it is called “Cold galvanizing compound”.

Coating process

Epo Roval Painting process

EPO ROVAL can be used together with top-coat from other companies.

Under coat 1EPO ROVAL (40μm)
Under coat 2EPO ROVAL (40μm)
Intermediate coatModified Epoxy paint *1
Top coatUrethane or Fluorine paint

*1 Different types of paint may be exposed to a serious bubble phenomenon, please do mist treatment.
Note: Do not use phthalate, alkyd and other oil-based paint, because they will case the film peeling off.

EPO ROVAL only coating is also available. However in such cases, ROVAL is cheaper than EPO ROVAL. See the next article for details.

Compare with ROVAL

ROVAL and EPO ROVAL are equivalent in terms of anti-corrosion performance.
The differences are as follows.

Anti-corrosion performanceVery highVery high
Top coat applicabilityN / AApplicable
Heat resistance170˚C300˚C
Solvent resistanceLowHigh

Color weathering of EPO ROVAL

The film of EPO ROVAL weathers the same as galvanized materials by exposure.  This characteristics makes repaired unapparent.
The color change is proof that the film protects iron by oxidizing zinc in the coating.
This color change is not abnormal and does not affect the rust prevention performance.
The photo below shows a plate with EPO ROVAL coating on the upper half of a galvanized plate.
