Topcoat 80 µm

Steel

Primer 80 µm

Barrier to moisture and aggressive chemicals + provide film thickness

Active corrosion protection (barrier against oxygen, water and ions) + adhesion to metal surface

Application field: mid and low demand (air-drying) coatings for the maintenance, transportation and DIY segments.

Intermediate Coat 80 µm

Aesthetics + better impermeability and weatherability
