Component cleaning & corrosion protection
03 / BUSINESS AREA

Component cleaning & corrosion protection

Surface treatment for uncoated components during machining, forming, handling, storage and service.

Treatment goals
Assess cleaning, rust prevention and applicable corrosion treatment against the substrate and service conditions.
Scope
The literature includes steel and die-cast aluminium, zinc, magnesium and copper components. Passivation systems must be selected by substrate.
Application review
Substrate, surface condition, protection duration, storage and transport environment and permitted residues.
Discuss this area

These areas reflect the scope described in our company literature. The catalogue covers six groups: degreasing, dewaxing, rust removal, silane and films, metal passivation, and rust prevention and sealing. Contact us to discuss the specific process.
