ROPAQUE™ AF-1570 Hollow Sphere Pigment

Hollow Sphere Pigment used in insulating pre-coat of thermal paper and is found in most types of direct thermal paper (point of sale, top-coated, label grades etc). Its low density, smooth surface and excellent runnability give significant performance benefits over traditional inorganic pigments such as calcined clay. The smoothness and high insulating power allow papers with high sensitivity at low energy with reduced use of costly imaging layer chemicals. The low dry density compared to inorganic pigments means that high coating thickness and bulking are achieved at low coat weights.
