Geomet 720 Coated Fasteners

Stud Bolts, Nuts, Screws, Threaded Rod & Washers

GEOMET® 720 is applied to protect fasteners and many types of metallic parts from corrosion and is used in many industries. It can be combined with PLUS® topcoats to provide a very broad range of friction coefficients. It is the reference zinc flake coating in Asia

  • Thin dry-film, non-electrolytic
  • Water-based chemistry
  • Passivated zinc and aluminum flakes in a binder, patented chemistry
  • Metallic silver appearance

Application process

GEOMET® 720 can be applied by Dip-Spin, Spray, Dip-Drain-Spin using bulk or rack

Health and Safety

  • Aqueous dispersion
  • Complies with REACh Complies with the 2000/53/CE and 2002/95/CE directives

GEOMET® 720 Characteristics and performance

  • The coefficient of friction can be adjusted to targeted values ranging from
  • 0.06 to 0.20 (ISO 16047) with NOF METAL COATING GROUP’s selected topcoats
  • Can be used with or without topcoat
  • No hydrogen embrittlement
  • Excellent assembly and multi-tightening behavior (with lubricated topcoat)
  • Performance maintained at elevated temperatures (up to 300°C)
  • Paintable coating
  • Electrical conductivity for most application processes
  • Bimetallic compatibility with aluminum

GEOMET® 720 Corrosion Resistance

Coating Weight Salt Spray Test (ISO 9227 / ASTM B117)
24 g/m2 > 1000 hours without red rust
> 24 g/m2 + topcoat > 1500 hours without red rust
  • Results may vary depending on substrate, geometry of parts and type of application processes
