With the process of washing, etching and passivation of aluminum alloy or aluminum cast components, we can remove any kind of oil or grease and protect those components with a very thin passivation layer. This passivation layer is an excellent primer for subsequent coatings, adhesives, powder coatings, e-coatings and guarantee, by their adhesion-promoting properties, a very good corrosion protection. Also, our automotive customers prefer it because welding is possible afterwards.

In the HEICHEGROUP the following etch passivations are used: Alodine 2040 from Henkel or Gardobond X4707 Chemetall . We offer this service to you at all our plants.

We offer this process in all our locations. For additional information please contact: info@us.heichegroup.com
