Principal Properties
The surface is finished with Lumiflon-based flurocarbon coating on the topside and a service coating on the reverse side. There are two types of coating system for Lumiflon-based fluorocarbon coating.
- "Solid Color" is a two-coat, two-bake system.
The total dry film thickness of the top is 25µ minimum and consists of a conversion coat, an inhibitive primer and Lumiflon-based fluorocarbon color coat.
- "Metallic Color" is a three-coat, three-bake system.
The total dry film thickness is 35µ minimum and consists of a conversion coat, an inhibitive primer, metallic and clear Lumiflon-based fluorocarbon coat.
The top coated surface shall comply with the "Specification for coated coil exterior building applications" issued by ECCA(European Coil Coating Association) or AAMA(American Architectural Manufacturers Association) to achieve the quality level for each Association. The reverse side of the cladding panel surface facing the wall shall have a polyester-based wash coating to protect against possible corrosion problems.
The surface finish is also available with Stone Series which has the appearance of stone and is coated with Lumiflon-based fluorocarbon resin. The color and the pattern can be selected by the architect. These coatings are applied in the manufacturer's continuous coating lines.
The finishes surface is protected with a self-adhesive peel-off protective film with two layers-white and black, tested to withstand at least six-month exposure to local weather conditions without losing the original peel-off characteristics or causing stains or other damage.
The painted finish, according to the tests by the manufacturer, meets the following criteria:
