ROVAL vs Other Anti-corrosion Paints

Flash movie ver.

1.Atmospheric Exposure Test

We have proven results from a 36-month atmospheric exposure test concluded at Japan Weathering Test Center in Miyako-jima Island testing ROVAL and other companies’ paints for anti-corrosion performance.

ROVAL

No rust found.

Epoxy paint+Urethane topcoat

Rusts around cross-cut area.

Epoxy paint+Fluoropolymer topcoat

Rusts around cross-cut area.

JIS anti-corrosion paint+Phthalic topcoat

Rust spreads all over.

2.After the removal of films

ROVAL

No rust spreading from cross-cut area.

Epoxy paint+Urethane topcoat

Rust spreading from cross-cut area.

Epoxy paint+Fluoropolymer topcoat

Rust spreading from cross-cut area.

JIS anti-corrosion paint+Phthalic topcoat

Rust developing in area other than cross-cut.

These results and pictures prove that ROVAL protects steel surfaces from rust creepage with its electrochemical reaction, whereas other paints allowed the rust to spread from the cross cut areas.
