OptaKoat

Even though it is comprised of a dense nickel phosphorous coating, OptaKoat differs from traditional electroless nickel plating. In short, it offers significant improvements in both diamond tool life and coated component yield.

Specifically developed for the Optics and Diamond turning industry, Optakoat is highly reflective and can easily be diamond turned. Furthermore, this coating thickness is applied at 0.25″ or more — therefore significantly reducing imperfections.

Additionally, this coating is totally amorphous. That is,  typically used in producing  technical lenses for mobile phones, Compact Disc and DVD players. OptaKoat is also used in creating rollers for lenitcular lenses, digital printing parts and injection mold dies for example.

With over 50 years experience in the metal plating industry, Techmetals offer similar coatings for optical use, such as Optical EN and Silver plating.

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
