A practical solution to quickly and easily chemically blacken and protect steel and iron.<\/p>\n
Verzinkshop Black Oxide Ultra is a newer cold black oxide system based on milder acids that gives a very dark, even black finish in minutes. It works according to the same steps as Verzinkshop Zwart Oxide<\/a>, with an even darker final colour with correct post-treatment. Developed for cold chemical blackening of iron and steel with minimal impact on dimensions, ideal for steel furniture, panels, restoration projects and components, among others. Not suitable for stainless steel. <\/p>\n Available in:<\/p>\n Need a large quantity? Please contact us<\/a> . <\/p>\n <\/p>\n <\/p>\n Very professional product, suitable for both professionals and hobbyists.<\/p>\n <\/p>\n A black-oxide conversion layer in itself has limited anti-corrosion properties. Without a sealer, the layer will further oxidize in contact with moisture and oxygen. Therefore, always apply a water-repellent sealer, preferably while the surface is still wet after rinsing. <\/p>\n <\/p>\n This product works very well on structural steel and well-cleaned steel plates and parts. It meets the principles of the Living Building Challenge Red List. <\/p>\n Follow the steps to get an even black-oxide finish:<\/p>\n <\/p>\n The liquid can be stored in a sealed container for several months and reused. Performance depends on hygiene, load and maintenance (replenishment\/filtering). <\/p>\n The black-oxide finish is not rust-resistant by itself and cannot be applied without a sealer. The conversion layer continues to oxidize without a protective layer. <\/p>\n This product does not work on stainless steel, use the Verzinkshop Black Stainless Steel Concentrate<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" Verzinkshop Black Oxide Ultra concentrate – black oxide concentrate for cold chemical blackening of iron and steel.<\/p>\n","protected":false},"featured_media":15013,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"parent_description":" <\/p>\n A practical solution to quickly and easily chemically blacken and protect steel and iron.<\/p>\n Verzinkshop Black Oxide Ultra is a newer cold black oxide system based on milder acids that gives a very dark, even black finish in minutes.
