OptaKoat

OPTAKOAT® is a dense nickel phosphorus plating specifically developed for the Optics & Diamond turning industry.

The deposit is highly reflective, can easily be diamond turned and coated to a thickness of 0.25″ or more — therefore significantly reducing imperfections.

OptaKoat

OPTAKOAT has several advantages over current coatings used for diamond turning (such as Electroless Nickel), including significant improvements in both the diamond tool life and
coated component yield.

This coating is totally amorphous and typically utilized industrially in the production of technical lenses for mobile phones, CD and DVD players. OPTAKOAT is also used in creating rollers for lenitcular lenses and digital printing, injection mold dies and more.

Benefits of OPTAKOAT:

  • Extends Diamond Tool Life
  • Lasts up to 8 times longer than Electroless Nickel (EN)
  • Non-magnetic
  • Fewer defects than EN
  • Polishes to a superior finish
  • Corrosion and wear resistant
