GEOMET®

titre-dacromet-prod

A time-proven reliable coating for corrosion protection

For more than 35 years, DACROMET® has been used worldwide for
high performance corrosion protection on wide variety of metallic parts

  • Thin dry-film, non-electrolytic, self-lubricated or not
  • Water-based chemistry
  • Passivated zinc and aluminium flakes in a binder, patented chemistry
  • Binder contains chromium oxide (Cr3+ and Cr6+)
  • Metallic silver appearance

Characterictics and performance*

  • Controlled coefficient of friction (ISO 16047):
    DACROMET® 320 + PLUS® or DACROLUB® topcoat ⇒ μ from 0.06 to 0.19
    DACROMET® 500 ⇒ μ = 0.15 ± 0.03 without topcoat
  • No hydrogen embrittlement
  • Excellent assembly and multi-tightening behavior (with lubricated topcoat)
  • Good mechanical damage resistance (trial method D24 1312, USCAR 32)
    and chemical resistance (trial VDA 621-412)
  • Suitable for high-temperature applications (up to 300°C)
  • Paintable coating
  • Electrical conductivity for most application processes
  • Competitive application costs
  • Bimetallic compatibility with aluminum

 

* Results may vary depending on substrate, geometry of parts and type of application processes

Application process

DACROMET® can be applied by Dip-Spin, Spray or Dip-Drain (Spin) using bulk or rack
