UV Fluorescent Pigment Infrared Pigment Invisible Pigment Anti-Counterfeit Fluorescent Pigment for Security Feild
UV Yellow W3A
Anti-counterfeit fluorescent pigments, such as long wave (365nm) UV fluorescent pigments and short wave (254nm) UV fluorescent pigments, which are produced by special ways. These pigments are white, or pale yellow, or pale red while they glow bright red, yellow, green, and other colors. Long wave (365nm) UV fluorescent pigments can be excited by long wave UV light with 365nm wavelength, while short wave (254nm) UV fluorescent pigments can be excited by short wave UV light with 254nm wavelength.

soluble UV Anti-counterfeiting Fluorescent pigment powder for invisible inks
UV Green W3A
Anti-counterfeiting Fluorescent pigments quickly release energy after absorbing the energy of ultraviolet or infrared light，show bright color fluorescent effect，when the light source moved，immediately stop lighting，restore the original invisible state，so it is also called invisible phosphor.

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.
