Presto Black®
Cold Burnishers and Anti-Corrosion Protectors
The Presto Black® System.
The Presto Black® system is the easiest and fastest method of cold-burnishing metals, especially ferrous metals.
Presto Black® has a wide range of color shades from black to brown, including all shades with “antiqued” touch-ups. This system is particularly suitable for all those small productions for which quick assembly with excellent aesthetic impact and good corrosion protection is required. Items treated with this system generally include cutting tools, tool holders, measuring instruments, gears, hand tools, castings, and components for machine tools and the automotive sector.
The Presto Black® range also includes fixing and protective products (anti-rust, coatings) as well as degreasers and activators to facilitate the blackening process.
The steps of the cycle
Greasing
The parts must be completely clean.
Burnishing
Immersion for 60 sec. in an aqueous solution, during which color conversion takes place.
Fixing
Immersion in protective oil that drives away water, seals pores and protects against corrosion.
