Typical of these coatings are chromates, triazoles, clear <a href=\"https:\/\/advancedplatingtech.com\/powder-coating\/powder-coating-services-milwaukee-wisconsin\/\" target=\"_blank\" rel=\"noopener\">powder coatings<\/a> and lacquers. Mechanical barriers are also used to minimize exposure to oxygen and moisture. Typical of these are desiccants and various types of protective wraps.<\/p>\n<p>Advanced Plating Technologies can provide many options to minimize the tarnishing of a plated deposit including nitrogen bagging.\u00a0 In nitrogen bagging the oxygen that is responsible for forming metal oxides is removed by filling the bag with pure nitrogen.\u00a0 APT will guarantee protection from tarnish for your product for up to one year if nitrogen bagging is specified.<\/p>\n<p><a href=\"mailto:quetes@advancedplatingtech.com?subject=General%20RFQ\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-5591 size-full\" src=\"https:\/\/advancedplatingtech.com\/wp-content\/uploads\/2021\/12\/Submit-RFQ-5-e1646066165902.png\" alt=\"\" width=\"342\" height=\"45\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Avoid Tarnishing All metals with the exception of the precious group (gold, palladium, platinum, rhodium) are subject to tarnishing. \u00a0This&hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":122,"menu_order":0,"comment_status":"open","ping_status":"open","template":"","meta":{"_acf_changed":false,"jetpack_post_was_ever_published":false,"footnotes":""},"class_list":["post-1853","page","type-page","status-publish","hentry"],"acf":[],"jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/P7G6ce-tT","_links":{"self":[{"href":"https:\/\/advancedplatingtech.com\/wp-json\/wp\/v2\/pages\/1853","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/advancedplatingtech.com\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/advancedplatingtech.com\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/advancedplatingtech.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/advancedplatingtech.com\/wp-json\/wp\/v2\/comments?post=1853"}],"version-history":[{"count":0,"href":"https:\/\/advancedplatingtech.com\/wp-json\/wp\/v2\/pages\/1853\/revisions"}],"up":[{"embeddable":true,"href":"https:\/\/advancedplatingtech.com\/wp-json\/wp\/v2\/pages\/122"}],"wp:attachment":[{"href":"https:\/\/advancedplatingtech.com\/wp-json\/wp\/v2\/media?parent=1853"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
