The paints’ features
The thickness of the paint layers applied on the steel coils is as following:
Primer: 5-7 µm
The types of primer used are: PU (polyurethane), Epoxy and Polyester. The primer prevents the appearance of corrosion and increases the paint adherence
Top coat: 15 -25 µm
The “top coat” types that we use are: PE (polyester), SMP, PVDF, PU (polyurethane), PVC, and Acrylic. The “top coat” prevents the appearance of corrosion, increases the adherence of the paint and improves the workability and the resistance to the ultraviolet incidence
Back coat: 8-15 µm
The back coat prevents the appearance of corrosion and increases the adherence of the paint to the polyurethane foam.
Colors: RAL 3011, RAL 3009, RAL 3005, RAL 8017, RAL 5010, RAL 6005, RAL 9002, RAL 9006 or other colors at customers’ request.
