Substrate and Base Finish
State the steel grade, product form, dimensions and base appearance. Identify any PVD layer and the faces requiring the topcoat.
SUBSTRATE + TOPCOAT
Requirements for the Finished Surface
The finished component, its handling and cleaning conditions, and its fabrication route help define the topcoat sample and inspection requirements.
Appearance and Use
Provide the colour and gloss sample, visible areas, handling and cleaning conditions. Describe the finger-mark appearance and other surface requirements to assess.
Sample and Inspection
Include subsequent forming, stamping or bending, the inspection stage and acceptance criteria. A reference sample defines the combined finish before ordering.
Anti-Fingerprint Topcoat
A transparent topcoat, with standard AF and nano AF options, applied over Hairline, No.4, mirror, etched, blasted or PVD surfaces. Agree any colour or gloss change using a sample.
Sheet substrate
- Reference grades
- 201, 304, 304L, 316, 316L, 430
- Metal substrate thickness
- 0.3–3.0 mm
- Specification details
- Sheet size is confirmed with the substrate and topcoat requirements.
Uses and Order Requirements
Order Requirements
Specify the substrate, base finish, any existing PVD layer, final appearance, visible faces, downstream processing, cleaning environment, inspection and protection requirements.
PVD + Anti-Fingerprint Topcoat for Strip
An additional film-removal, topcoat-application and curing route after PVD colour coating, followed by protective film and packaging. Specify the colour layer, topcoat and removable protection film separately.
PVD-coated strip with topcoat
- Reference grades
- SUS430M, SUS436M
- Specification details
- Substrate thickness, width, coil requirements and total layer requirements are confirmed with the order and sample.
- This strip reference describes the PVD-plus-topcoat route.
Uses and Order Requirements
Order Requirements
Specify the substrate, base surface, colour sample, final gloss, subsequent roll forming, stamping or bending, cleaning and inspection requirements.
Transport and Processing Protective Film
A removable film selected for transport, laser cutting, bending or stamping. It is separate from a permanent decorative laminate, the PVD colour layer and an anti-fingerprint topcoat.
Removable film
- Removable film reference
- Film thickness references: 60, 70, 75, 80, 100 and 105 μm (0.060, 0.070, 0.075, 0.080, 0.100 and 0.105 mm). Select the film type to suit the processing and removal requirements.
- The listed thicknesses refer to removable protection film, not to the metal substrate or PVD layer.
Uses and Order Requirements
Order Requirements
Specify the protected surface, laser type, downstream forming, film thickness, adhesion and removal requirements, residue acceptance and packaging.
PROCESS FLOW
Anti-Fingerprint Topcoat Processing
When a PVD-coated coil requires a composite anti-fingerprint topcoat, these operations follow PVD coating.
Protective-film removal
Topcoat application and curing
Final protective-film application
Inspection and packaging
PVD-Coated Coil with Anti-Fingerprint Topcoat
Roll forming, stamping and bending are downstream operations. Include the intended part and forming requirements when discussing the coating and sample.
