Surface treatment & corrosion protection.
Clean, well-defined surfaces are the basis for adhesion, function, and protection. From cleaning and conversion coating to conductive coating: the right pretreatment determines the result.
overview
Basics
Surface treatment creates the conditions necessary for coatings, adhesives, and functional layers to adhere and function properly. It begins with cleaning and degreasing, as grease, release agents, and particles would otherwise prevent adhesion. A conversion coating chemically transforms the metal surface into a firmly adhering layer, improving corrosion protection and providing a base for paints and adhesives. Conductive coatings, also known as conductive paints, make surfaces electrically conductive, enabling printed circuits, heating surfaces, and protection against electrostatic discharge. The appropriate process depends on the material, function, and subsequent processing; the technical data sheet is the definitive source of information.

FAQ
Frequently Asked Questions
Why clean before gluing or coating?
Adhesion occurs through direct contact between the adhesive or coating and the substrate. A thin layer of grease or release agent prevents this contact. Cleaning and degreasing are therefore essential for a durable bond.
What is a conversion layer?
A chemically produced, firmly adhering layer on the metal surface, for example through phosphating or passivation. It serves as corrosion protection and as a base for paints and adhesives. The process and product data sheets are binding.
What are conductive coatings used for?
Conductive coatings make surfaces electrically conductive, enabling printed resistors, heating elements, membrane keypads, and protection against electrostatic discharge. The required conductivity is described by the surface resistance in the datasheet.
