LUMILEAD TNO

What is LUMILEAD?

LUMILEAD is a coined word created from LUMINOUS and LEAD.
It is a brand name for our new evaporation material that will be a leading role player in the optical industry.

Characterstic

  1. Antistatic performance (prevention of dust adhesion)
  2. Antistatic effect will ben incorporated by simply using LUMILEAD TNO instead of Common titanium oxide materials in the multilayer coating.
