Precipitated calcium carbonates (PCC), unlike ground or natural calcium carbonate, perform more than just as a filler in coating and ink applications. Particle size, brightness, and rheology all play a significant role in increasing the hiding power of the coating. Particle size plays a critical role in the selection of calcium carbonate materials. Consideration must be given to the impact the particle size will have on physical properties, as well as processing characteristics. Magnum Fill® and Magnum Gloss R precipitated calcium carbonates are ideal for these applications.
In the Ink Market, print gloss, water release, tack times, and opacity are key parameters that can be influenced by the choice of pigment. Mississippi Lime provides calcium carbonate products across a broad spectrum of particle sizes, shapes, oil absorptions, and specific gravity. In the powder form - Magnum Fill® SD, Magnum Fill® M, Magnum Fill®SDL, Magnum Fill® HO97, Magnum Gloss® SD, and Magnum Gloss® M. In the slurry form - Magnum Fill® 65%, and Magnum Gloss® 72%.
In the Paint Market, brightness, wet and dry hide, and gloss are some of the key parameters that can be influences by the choice of pigment. Mississippi Lime PCC products are available in a wide range of both chemical and physical properties tailored to meet the needs of the Paint Market. Magnum Gloss® 72% provides a superior level of gloss and brightness in satin and semi-gloss paints as well as industrial coatings. Magnum Gloss® M is a further processed version of Magnum Gloss® SD to enhance Hegman grind, oil absorption and particle size characteristics. There are two types of Magnum Fill® Slurry products: Magnum Fill® 50% Stabilized is a high opacity, high oil absorption product designed for paint applications. Magnum Fill® 65% stabilized is a high solids functional filler in paint applications. Magnum Fill® Powder products manufactured at our plant in Ste. Genevieve, MO: Magnum Fill® SD is an excellent functional filler having good opacity and optical properties. Magnum Fill® M is a Magnum Fill® product that is further processed to improve the physical characteristics such as particle size and Hegman grind/dispersability.
