kopergecoat

Kopergecoat is a copper-based coating system designed for protecting metal surfaces while incorporating copper’s antimicrobial properties. The name blends the Dutch word koper, meaning copper, with coat, reflecting its copper-rich surface layer. The system typically includes a copper-containing sublayer and a polymer-based topcoat that seals the layer and provides durability.

Variants of kopergecoat may differ in copper content, deposition method, and topcoat chemistry. Common application methods include electroplating, chemical deposition, or spray coatings, followed by curing or drying to achieve adhesion and chemical resistance. Typical dry film thickness ranges from a few micrometers to about twenty micrometers, depending on substrate, service environment, and required barrier performance.

Applications encompass corrosion protection for steel, aluminum, and other substrates used in marine, architectural, and industrial equipment; electronics enclosures where conductivity is advantageous; and components where antimicrobial surfaces are beneficial. The coating aims to offer a barrier against corrosive media while enabling controlled release of copper ions to suppress microbial growth.

Key properties include improved resistance to corrosion in harsh atmospheres, potential antimicrobial activity, and compatibility with subsequent topcoats or paint systems. Limitations may involve cost considerations, the need for careful substrate compatibility to avoid galvanic effects, and environmental considerations related to copper usage and disposal.
