Microsphere fluorescent pigment VQ series is a kind of universal fluorescent pigment. At present, the most widely used is in various coatings, inks, and other fields, especially solvent-sensitive systems and other occasions that need to have excellent heat resistance and solvent resistance.
VQ series fluorescent pigments are composed of fine, opaque thermosetting microsphere particles with excellent dispersion and light scattering (opacity). It has strong coloring power, strong color, and pure. Its anti-dialysis properties make it particularly suitable for a variety of vinyl plastics, plastics, and applications and can be used in a variety of solvents, so it can be used in a variety of media.
