    Infrared Invisible Pigment (980nm) for Security Printing

    Infrared Invisible Pigment (980nm) also called 980nm up-Conversion Infrared Pigment,It is white color powder form while under infrared ray,it will show color. when move away from infrared ray, it will back to white color;

  • UV reactive fluorescent pigment uv invisible pigment

    UV reactive fluorescent pigment uv invisible pigment

    The UV reactive fluorescent pigment  is a special pigment that is very sensible to the exposure at short-range UV wich is also known as ”black light. 

    UV reactive fluorescent pigment lights up intensively under UV light.

  • UV Fluorescent Pigment Infrared Pigment Invisible Pigment Anti-Counterfeit Fluorescent Pigment for Security Feild

    UV Fluorescent Pigment Infrared Pigment Invisible Pigment Anti-Counterfeit Fluorescent Pigment for Security Feild

    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

    soluble UV Anti-counterfeiting Fluorescent pigment powder for invisible inks

    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 invisible pigment

    uv fluorescent invisible pigment

    The fluorescent pigment is invisible to the normal light, it only glows bright in the light of the blacklight lamps. For maximum effect it is recommended to use UV lamps with a wavelength of 365 nm and transparent paints.

  • invisible security pigment

    invisible security pigment

    invisible security pigment also called uv fluorescent pigment,Ultraviolet fluorescent Pigment.

    These pigments are neutral in color, with a white to off-white powder appearance. Not noticeable when incorporated into security inks, fibres, papers. When irradiated with 365nm UV light, the pigment emits fluorescent radiation of yellow, green, orange, red, blue and violet colors and so is immediately identifiable.

     

  • UV Fluorescent Security Pigments

    UV Fluorescent Security Pigments

    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 Invisible fluorescent pigment

    UV Invisible fluorescent pigment

    The UV invisible fluorescent pigment is invisible to all kinds of light excepting UV light.

    It works great for creating images, drawings and other hidden texts that can be revealed by a uv lamp only.

    For best results we recomend using UV lamps 365 nm wavelength.
