ROPAQUE™ AF-1570

Used in the 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. ROPAQUE AF-1570 is typically used as the sole pigment in pre-coats (100 dry parts) at coat weights below 3 g/m2.
