Henkel’s Alodine 160/161 is a rapid process to create a conversion coating on the surface of light metals to provide enhanced corrosion protection and improved paint adhesion. The passivating coating created is formed in seconds and has an attractive yellowish or straw colour.
Alodine 160/161 is a chrome-free passivation process for aluminium, magnesium, and their alloys. The product is supplied in liquid form and diluted with deionised water. Metal components are then simply dipped into the solution and the conversion process begins automatically. The dip bath is maintained at moderate temperature – 15-30C – and the conversion time is just 15-180 seconds.
The Alodine 160/161 process complies with the recent European Union (EU) WEEE and RoHS directives. The coating does not affect the electrical conductivity of the parent metal and provides an excellent key for paint or other organic coating.
