Opacarb^® precipitated calcium carbonates (PCCs) are a family of Specialty Minerals Inc.’s (SMI’s) products designed for coated paper and paperboard applications. With a range of aragonite particle sizes and narrow particle-size distributions, Opacarb^®  PCCs are tailor-made to maximize fiber coverage and light scatter. From glossy to matte finishes, Opacarb^® PCC provides both brightness and opacity increases not attainable with other commercial calcium carbonates.

Opacarb^® PCC is ideal as a precoat or a topcoat pigment for offset and rotogravure printing on paper or board. Color print images are sharp and vibrant due to its narrow particle-size distribution, which provides an optimal coating structure for porosity control.
