It thus enables the number of process baths to be decreased and pre-treatment lines to be reduced in length.<\/p>\n<p>In fact, if using an alkaline degreaser, it is possible to eliminate the etching tank altogether, which currently cannot be achieved using any other product on the market.<\/p>\n<p>Rinse or multiple rinse stages can also be eliminated, while a DI (deionised water) rinse can be replaced with a conventional tap water rinse in some applications.<\/p>\n<p>As it contains a small quantity of surfactant, BONDERITE M-NT 2040 R2 can be used as a cleaner-coater, effectively replacing conventional degreaser products.<\/p>\n<p>At a customer in Europe, this allowed an existing pre-treatment line to be reduced from six tanks (alkaline degreaser, rinse, rinse, Chrome-VI, rinse, DI rinse) to just four (cleaner-coater, BONDERITE M-NT 2040 R2, rinse, DI-rinse), thus boosting productivity significantly using a non-chromic process without any detriment to performance.<\/p>\n<p>Another benefit is that existing green chromating lines can be converted to the new <span class=\"highlight highlight-blue\"><a href=\"https:\/\/engineernewsnetwork.com\/blog\/henkel-unveils-dedicated-bondertite-functional-coatings-website\/\">BONDERITE<\/a><\/span> process without modification to the active baths.<\/p>\n<p>Moreover, it can be used at room temperature (around 25\u00b0C), leading to significant energy cost reductions, while both water and wastewater are likely to be reduced by up to 70% due to fewer baths.<\/p>\n<p>BONDERITE M-NT 2040 R2 is also suitable for multi-metal lines. With this in mind, adoption of the product can help plants transform from a facility suitable only for aluminium, to one that is capable of processing multiple metal types.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Henkel has developed BONDERITE M-NT 2040 R2, which is formulated using only non-toxic, chrome-free components.
