PREMIUM DIE CAST FINISH<\/h1>\n<\/div><\/div><\/div>\n\n\n\n

Process: Zinc die-cast<\/strong>
Application: Barrel application<\/strong><\/p>\n\n\n\n

PREMIUM DIE CAST FINISH is a WHW Hillebrand process for direct passivation of zinc die-cast materials. Geometrically challenging materials, such as handle parts, classic frame articles or even typical mass-produced materials for barrel coating can be very effectively protected against corrosion even without previously being galvanised. Here, the articles are first pre-treated and then provided directly with a protective layer which protects against base metal corrosion for > 200 hours in the salt spray fog test in accordance with DIN ISO 9227.<\/p>\n\n\n\n

Unlike conventional methods, organic sealants can be dispensed with without sacrificing performance. For this purpose, passivation and subsequent inorganic dipping are combined. The typical crack-like structures which appear in the applied passivation layer are filled and levelled with the functional polymer groups. High corrosion protection combined with a high quality look is the result of this zinc die-cast surface.<\/p>\n\n\n\n

Wherever sealants are not able to be used or desired to be used for technical reasons, but above-average corrosion protection is necessary, PREMIUM DIE CAST FINISH is a convincing choice.<\/p>\n\n\n\n

Layer structure<\/h3>\n\n\n\n

The system consists of a passivation and a post-dip solution which protects the cast component from zinc corrosion. The passivation penetrates into the pre-treated porous zinc die-cast surface and protects it against self-corrosion. The reactive post-dip solution then forms a thin protective layer and seals the surface completely.<\/p>\n<\/div>\n\n\n\n

Corrosion protection<\/h3>
<\/div>

The substrate is gently cleaned according to the specific material. Release agents from the casting process are effectively removed here. After an activation step, a thick-layer passivation takes place which, after the rinsing process, chemically binds with the functional groups of the inorganic post-dip solution. This develops the high corrosion protection.<\/p><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n\n","protected":false},"template":"","meta":{"brand":"whw-hillebrand","service_description":"Direct passivation for high corrosion protection\neven with complex geometries especially for the automotive industry.","service_image":946},"system":[91],"class_list":["post-2578","service","type-service","status-publish","hentry","system-zinkdruckguss-systeme-en"],"_links":{"self":[{"href":"https:\/\/www.whw.de\/en\/wp-json\/wp\/v2\/service\/2578","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.whw.de\/en\/wp-json\/wp\/v2\/service"}],"about":[{"href":"https:\/\/www.whw.de\/en\/wp-json\/wp\/v2\/types\/service"}],"wp:attachment":[{"href":"https:\/\/www.whw.de\/en\/wp-json\/wp\/v2\/media?parent=2578"}],"wp:term":[{"taxonomy":"system","embeddable":true,"href":"https:\/\/www.whw.de\/en\/wp-json\/wp\/v2\/system?post=2578"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
