UV Fluorescent Security Pigments
UV Green Y2A
Topwellchem manufacture a range of organic and inorganic security pigments that are excited by both short and long wave UV light (as well as special dual excitation/emission products). Emissions span the range of visible colours and are generally intense and lightfast.

UV Fluorescent Pigments for security
UV White W3A
Topwell chemical develops and manufactures a range of organic and inorganic security pigments.
General introduction:
Under visible light, the UV Fluorescent Pigment color is white or nearly transparent. But under UV 254nm and 365nm light, the pigment show one or more fluorescent color. The main application is to prevent from counterfeiting.
It is also called UV phosphor pigment, security pigment.
-
invisible pigment
UV Orange Y2A
The invisible pigment powder reacts under ultraviolet rays. when under uv lamp，will change very brightly！
invisible pigment also called uv invisible pigment，UV fluorescent powder.
they have many applications, the main applications being in anti-counterfeiting inks and lately also in fashion division.

uv fluorescent pigments powder
UV Green W2A
The UV fluorescent powder reacts under ultraviolet rays. UV fluorescent powder has many applications, the main applications being in anti-counterfeiting inks and lately also in fashion division.
-
365nm organic uv fluorescent pigment for security ink
UV Red W2A
UV Fluorescent security pigment are able to absorb non-visible light in the UV‑A, UV‑B or UV‑C region and emit visible light in the whole range of the visible spectra.
Uv fluorescent pigment is colorless in visible light and glows brightly under UV lamps
-
uv fluorescent pigment for anti-falsification printing
UV Yellow W2A
UV fluorescent pigment itself is colorless, and after absorbing the energy of the ultraviolet light (uv-365nm or uv-254nm), it rapidly releases energy and exhibits a vivid color fluorescent effect. When the light source is removed, it stops immediately and back to the original invisible state.
