GEOMET®

GEOMET®


GEOMET®, developed as a chromium-free solution to the environmental regulations enacted by the government and automotive industry, is the next generation in the Metal Coatings International product line. GEOMET® is commonly specified in the wind turbine, automotive, heavy truck, marine, agricultural, construction equipment and aerospace industries. GEOMET® is a water-based, VOC-compliant coating comprised of overlapping zinc and aluminum flake in an inorganic binder.

Four-Way Corrosion Protection

  • Barrier Protection: Overlapping zinc and aluminum flakes provide an excellent barrier
  • Galvanic Action: Zinc corrodes to protect steel
  • Passivation: Metal oxides slow down the corrosion reaction of zinc and steel
  • Self-Repairing: Carbonates migrate to damaged areas to actively repair and restore the coating

GEOMET® Advantages

  • Thin: GEOMET® 321: 7-8 microns; GEOMET® 321 L: 8-10 microns
  • Hydrogen Embrittlement Free Process: Coating does not require acid pickling or electroplating
  • Bimetallic Corrosion Resistant: Aluminum flake eliminates the bimetallic cell of zinc coatings
  • Solvent Resistant: Inorganic nature causes it to be resistant to organic solvents
  • Heat Resistant: Maintains corrosion resistance even following an intermittent heat shock
  • Conductive: Concentration of metallic flakes allow an electrical current to be passed
  • Better Than Pure Zinc: 3 times greater corrosion protection than pure zinc

Environmental Benefits

  • Chromium Free: NO HEXAVALENT or TRIVALENT in the liquid or on parts.
  • Complies With: Environmental Protection Agency (EPA), Occupational Safety and Health Administration (OSHA), EU Directive on End of Life Vehicles (ELV) and EU Directive for Electrical Equipment (RoHS) regulations
  • No Toxic Metals: Free of nickel, cadmium, lead, barium and mercury
  • Water Based: Free from dangerous solvents
  • VOC Compliant: Under EPA RACT requirements

Versatile Application

Matenaer applies GEOMET® the rack application process (dip-drain-spin, spray) following an alkaline and/or mechanical cleaning cycle. Coating thickness can be varied by altering elements in the application processes. Due to its chemistry, GEOMET® has a wide cure window of 550°-625°F PMT (part metal temperature), for 15-20 minutes.

Available Colors

  • Matt Silver
  • Gloss Black
  • Other colors available upon request
