Product description

RAL 5021 sits at the meeting point of blue and green, which is why it gives a fashionable, deep petrol effect.

How does RAL 5021 differ from RAL 5018 and RAL 5001?

RAL 5018 (Turquoise blue) is clearly lighter and greener, while RAL 5021 stays dark and subdued. Against RAL 5001 (Green blue) the difference is smaller, since both have a petrol character, yet the water blue lies a touch closer to blue. RAL 5021 is a deep, slightly turquoise shade that shifts with the angle of light.

Parameters and resistance

The coating is applied electrostatically and then cured at 180°C for 10 minutes, at a recommended thickness of 90-120 µm. We offer the full gloss range, from matt (0-20%) to high gloss (86-100%), measured at 60° per ISO 2813. Adhesion reaches 5B in the cross-cut test. The thermosetting polyester version is TGIC-free (HAA-cured), UV- and weather-resistant, while the epoxy-polyester version is harder and more chemically resistant, for indoor use. Durability is confirmed by standardised elasticity and impact-resistance tests, and by QUALICOAT Class 1 certification and REACH and RoHS compliance. The surface does not fade and keeps its saturation.
