ND1.93 Transparent Glass Micro Bead
ND1.93 glass bead is high reflective glass bead, used for “Exposed-Lens” type retro-reflective articles (e.g., open-type reflective sheets, reflective fabric. reflective tape, reflective yarn) and “Encapsulated-Lens” type retro-reflective articles (e.g., high intensity grade reflective sheet).
the glass microbeads also called reflective powder, can be used for reflective ink, paint and in the fields of personal security and protective products.

Usage:
ND1.93 glass bead is used for “ Exposed-Lens” type retro-reflective articles (e.g., open-type reflective sheets, reflective fabric. reflective tape, reflective yarn) and “Encapsulated-Lens” type retro-reflective articles (e.g., high intensity grade reflective sheet ). It c an also be used for reflective ink, paint and in the fields of personal security and protective products.
Solution of getting strong retro reflective:
a. Ink must be clear and transparent, Grey. Yellow. Red will be better.
b. Firstly ,print aluminum powder as foundation. Then print with the mixture of ink and glass bead.(Aluminum coated glass bead need not)
c. Make the glass bead on the paint surface as more as possible.(ND2.2 glass bead need not)
