EU-Compliant Chrome-Free Passivation Drop-In
01 / Product brief
Zirconium/titanium-based chromium-free conversion coating for aluminium. Produces a colourless-to-light-blue conversion layer delivering 120–160 hours salt spray while fully meeting REACH, RoHS, and EU ELV requirements. Validated as a direct drop-in replacement for chrome systems.
REACH and EU ELV compliant — allows treated parts to enter European automotive and electronics supply chains without restriction. Drop-in chemistry requires no equipment modification versus existing chrome passivation lines.
02 / Performance
Product-specific outcomes for production quality, operating control and line performance.
Direct access to European OEM supply chains
Drop-in replacement for existing chrome lines
Strong corrosion performance without hexavalent chrome
