Minimalist Scandinavian Aesthetics
Modern architectural projects increasingly specify seamless all-white interior doors, requiring lock cylinders finished in Matt Pure White (RAL 9016 / 9003).
Electrostatic Powder Coating Protocol
- Pre-Treatment: Zinc phosphate immersion on solid brass to promote adhesion.
- Electrostatic Application: Architectural grade TGIC-free polyester powder sprayed at 60–80 kV.
- Curing & Performance: Baked at 200°C for 15 minutes, producing a 60–80 μm durable coat with ASTM D3363 3H pencil hardness and UV chalking resistance.
Frequently Asked Engineering & Selection Questions
Q1: How durable is white powder coating on lock cylinders?
High-grade architectural polyester baked at 200°C provides 3H pencil hardness and 480+ hours salt spray resistance, resisting chipping around keyways.
