Product Features
This product stands out for its rapid film-forming speed, even, dense film layers, pure film color, and absence of floating black spots. The resulting black film boasts strong adhesion and corrosion resistance.
Compared to traditional blackening processes for copper and copper alloys, the ambient temperature blackening process offers advantages such as energy savings (no need for high-temperature heating during the blackening process), time-saving (the blackening process takes approximately 2-8 minutes), ease of operation (no complex equipment or skills required), and better environmental benefits.

Application Scope
All copper and copper alloy components, such as various copper lighting fixtures, hardware, tools, standard parts, fasteners, mechanical components, molds, optical instruments, and electrical product parts, can be blackened using this process.
