Invisible UV Fluorescent Pigment
(365nm, 254nm)

Description:
UV fluorescent pigment absorbs energy and quickly releases the energy when activated by UV light (black light), therefore, it shows bright and colorful fluorescent effect. When UV light is removed, UV fluorescent pigment stops emitting light and restores its original near white color.
