Vacuum deposition and Vacuum Coating Technology

Acktar’s proprietary sophisticated vacuum deposition (vacuum coating) technology generates unique coating surface areas with exceptional characteristics, superior to those achievable by other processes that provide important commercial applications.

The application of Acktar vacuum coatings technologies leads to major improvements in a wide range of applications including, optical performances, solar energy, aluminum electrolytic capacitors, electronic enclosures, heat sinks, among others.

Below are some of the main characteristics of Acktar coatings:

  • Uniquely large specific surface area combined with very small coating thickness – 2000 times the substrate surface in a coating only microns thick
  • Close control of surface morphology – form and structure – for control of physical, optical and radiation characteristics
  • Retention of substrate thickness and mechanical strength – specific surface coating technology rather than etching technology.
  • Vacuum coating operating at temperatures: -269°C to +350°C
  • Excellent adhesion to metallic and non-metallic substrates
  • Excellent mechanical strength and abrasion resistance
  • Low outgassing
  • Ecologically clean – no aggressive chemicals used
  • Inorganic and completely nontoxic

Acktar’s proprietary sophisticated vacuum deposition (vacuum coating) technology generates coatings with an extremely high specific surface area. These coatings have unique characteristics – superior to those achievable by other processes – with important commercial applications.

The application of Acktar coatings grants major improvements in a wide range of applications.
Following are some of the main characteristics of the Acktar coatings:

  • Uniquely large specific surface area combined with very small coating thickness – up to 2000 times the substrate surface in a coating only microns thick
  • Controlled morphology, porosity and chemical composition of the coating allows tailoring of physical and optical properties.
  • Operating temperatures: -196°C to +450°C
  • Excellent adhesion to metallic and non-metallic substrates
  • Excellent mechanical strength and abrasion resistance
  • Totally ecologically friendly
    • Dry process and dry materials
    • No chemical wastes, no waste water
  • completely non toxic and Inorganic coating.
  • Electrically conductive coating / non conductive coating – both available.
  • Hydrophilic or hydrophobic surface characteristics available
