Copper Powder Coating
New Products From This Supplier
Introduction
Copper powder coating uses electrostatically charged copper-pigmented powder, often transparent or metallic, applied to surfaces and cured to create durable, decorative finishes that mimic real copper, ranging from shiny metallic to antique or patina looks, frequently layered over base coats like silver or black for depth, requiring specific settings (KV/microamps) and sometimes clear topcoats for protection and shine.
Key Aspects
Color & Finish: Available in various shades (antique, transparent, metallic) and finishes (gloss, satin, textured).
Application: A dry powder is sprayed onto grounded parts; an electrostatic charge makes it stick, then heat melts and cures it into a solid coating.
Base Coats: Often applied over a different color base (like silver or black) to alter the final appearance, especially with transparent copper powders.
Clear Coats: A clear topcoat is frequently added for enhanced durability, UV resistance, and to seal in the color, notes Prismatic Powders and YouTube.
Techniques: Creating effects like patinas involves layering colors and using methods like blowing off powder or brushing to achieve inconsistent coverage.
Common Uses
Decorative items, architectural features, automotive parts (wheels), and furniture where a copper aesthetic is desired without the cost or maintenance of actual copper.
