Hot sealing with this new product takes exactly 3 min/µm, fixed, as a standard sealing time. BONDERITE ® M ED 11011 is Henkel’s latest hot sealing additive, developed to at least double the standard life span of sealed parts and increase the productivity of single-step hot sealing by a minimum of 20 percent. Two highlights in Henkel’s dedicated product offering provide breakthrough solutions addressing demands for increased performance in hot sealing and minimized toxicity in cold sealing. The final step in the aluminum anodizing process is sealing. This also makes it an economic compromise between caustic soda and other long-life etching products. One of the company’s most recent product solutions in this field is BONDERITE ® C AK 62250, which has been custom-tailored to combine the required high etching and finishing levels with excellent bath stability, including reduced drag-out and no foaming.
E6 refers to a more thorough etching process compared to E0 and is frequently used to eliminate larger surface defects by actually removing part of the material. conventional two-component alternatives and is also highly reliable in removing residual brushing paste from the part surface.Īs a key player in the market of long-life etching additives, Henkel is well-known for its family of BONDERITE ® C AK products combining low chemical consumption with optimized E6 results. The one-component degreaser simplifies product handling vs. For brightened or high-gloss aesthetic parts that can’t be etched for anodizing, Henkel has developed BONDERITE ® C AK 62115. The first step in anodizing is always dedicated to degreasing the surface. The range is actually fronted by a new non-etching one-component degreaser, a long-life etching additive for outstanding E6 finish, and a high-productivity hot sealing as well as a nickel-free cold sealing additive.” “Our BONDERITE ® portfolio for aluminum anodizing comprises specialized products for all process steps, beginning with chemicals for mechanical pretreatment e.g.: grinding, polishing and cleaning up to the substances for the chemical process: degreasing, etching, desmutting, brightening, anodizing, electrolytical coloring and sealing. "As the demand for lightweight and aesthetic aluminum parts increases, manufacturers need cost-effective anodizing solutions to maximize both the productivity and sustainability of their processes,” says Raul Hernandez, Business Development Manager Light Metal Finishing for Henkel. Depending on the specific needs of the end product, the typical thickness of the anodized layer is normally just between 5 and 25 µm. In contrast, anodizing directly converts the outermost aluminum layer into a controlled thin and smooth oxide skin, reliably protecting the surface from further oxidization (corrosion). Although galvanic coating can be used to prevent this effect, it adds an extra layer of material and weight. In complementing its latest developments for optimizing the conversion coating of aluminum products, the company also offers improved BONDERITE ® technologies for the three key steps of degreasing, etching and hot or cold sealing in the aluminum anodizing process.Īluminum in its raw, unfinished state reacts with oxygen in ambient air and other weathering influences, resulting in an uncontrolled and undesirable, unaesthetic oxide layer. Henkel’s pipeline of innovations for the aluminum industry does not stop short when it comes to anodizing, one of the most established technologies of aluminum processing.
