BERLIN, May 2018:<\/strong> Aluminum is a very reactive metal and has a tendency to form an oxide layer very rapidly when in contact with oxygen. The presence of the oxide layer is not desirable in cases where the surface has to be metallized. The adhesion of subsequent coatings applied on the aluminum surface is adversely affected by the oxide layer. To avoid the rapid oxidation of aluminum during the pretreatment steps and prior to electroless nickel or electroplating, it is a common practice to cover the surface with a thin uniform film of zinc by use of a zincate process. In the case of electroless nickel (EN) plating, the build-up of zinc contamination limits the bath life to 3 – 4 MTO.<\/p>\n A new zincate process, Alumseal\u00ae 611<\/strong>, has been developed by jmÌìÌùÙÍø to provide very thin zinc coatings in order to reduce the amount of Zn contamination in the EN bath, thus eliminating the need for an EN strike bath. Alumseal\u00ae 611<\/strong> is designed to extend the bath life of the EN process to >6 MTO. Alumseal\u00ae 611<\/strong> has demonstrated that coating weight of the zinc film is reduced by 30 – 60% on aluminum alloys when compared to existing zincate processes.<\/p>\n \u201cWhen using the new Alumseal\u00ae 611<\/strong> zincate process in combination with the high Zn tolerant electroless nickel process Nichem\u00ae MP 1188<\/strong>, the bath life can be extended up to 8 MTO without an EN strike bath\u201d, states Shakeel Akhtar, Global Product Manager for Wear resistant coatings (EN) at Atotech. \u201cAtotech is the first company to achieve this milestone within the plating industry.\u201d<\/p>\n Due to low Zn build-up and high tolerance to Zn contamination, the efficiency of the EN bath is improved through higher average plating speed. The combination of Alumseal\u00ae 611 & Nichem\u00ae MP 1188<\/strong> provides technical and economic benefits for the customer in a highly demanding industry.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" Alumseal\u00ae 611 has been developed by jmÌìÌùÙÍø to provide very thin zinc coatings in order to reduce the amount of Zn contamination in the EN bath.<\/p>\n","protected":false},"author":40,"featured_media":43045,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"","iawp_total_views":1,"footnotes":""},"categories":[113],"tags":[],"class_list":["post-45846","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-press-releases-cn"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/posts\/45846","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/users\/40"}],"replies":[{"embeddable":true,"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/comments?post=45846"}],"version-history":[{"count":0,"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/posts\/45846\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/media\/43045"}],"wp:attachment":[{"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/media?parent=45846"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/categories?post=45846"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.atotech.com\/cn\/wp-json\/wp\/v2\/tags?post=45846"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
