Reflective coatings

Return

Especially developed for plastic reflectors

The LUMENCOAT coating is a premium optical product based on protected silver with an average reflectivity of 97% over the visible spectrum.

Industrial coating approved by major multinational companies.

This coating can also be deposited on metal or glass.

Other reflective coatings also available: in gold or aluminum.

PHYSICAL VAPOR DEPOSITION (PVD) – PROCEDURE

PVD (Physical Vapor Deposition) is a metal deposition coating process that allows thin films of material to be deposited under vacuum using vapor.

For PVD coating the deposition temperature is usually between 40 and 80 °C.

The deposit thickness is 400 nm.

Conforms to REACH and RoHS standards.

Applications

Silver coating

  • LED reflectors
  • Internal lighting
  • Mirrors
  • Encoders
  • Etc

The advantages

  • Very reflective surface (97% in the spectrum 400 to 800 nm).
  • Adherence test by tape (ASTM-D3359)>4B-5B (0-5%) 
  • Water soaking (24h) no delamination
  • Sulphurization test (ISO 4538) > no change in performance
  • High temperature storage (60-80°C; MIL Std 810G) > no change in performance
  • Low temperature storage (-40°C; MIL Std 810F) > no change in performance
  • Temperature cycling (-40°C to +80°C) > no change in performance
