Precipitated Calcium Carbonate

Mississippi Lime precipitated calcium carbonate (CaCO3), commonly referred to as PCC, is a bright, high purity mineral. Carbon dioxide is reacted with calcium hydroxide to form precipitated calcium carbonate with specific crystal morphology:

Calcium Hydroxide + Carbon Dioxide = Precipitated Calcium Carbonate
{Ca(OH)2} + {CO2} = {CaCO3}

Precipitated calcium carbonate is one of the most versatile chemicals used in the modern paint/coatings, ink and paper making markets today. PCC is a cost-effective material used to improve the physical characteristics of finished products. White pigments like PCC offer a wide variety of benefits in terms of gloss, brightness, opacity and viscosity.

Mississippi Lime’s precipitated calcium carbonate product lines are structured based on their end use functionality. Mississippi Lime’s calcium oxide product families and description are shown below:

  • The Magnum Gloss® family of products are designed for coating applications and are available in powder and slurry form.
  • The Magnum Fill® family of products are designed for filler applications and are also available in powder and slurry form.
  • VitaCal® PCC is high purity carbonate used in a variety of food industry applications.
  • PolyCal® PT1 Calcium Carbonate is a treated PCC produced for the PVC and plastics industries.

Magnum Gloss® Slurry PCC

Mississippi Lime Magnum Gloss® 72% slurry is designed for both the coatings and paper markets. For coatings, Magnum Gloss® 72% provides a superior level of gloss and brightness in satin and semi-gloss paints as well as industrial coatings. The significantly higher gloss is due in part to the tightly controlled particle range. Magnum Gloss® 72% is also used in glossy, high brightness coated paper and board applications. Due to its tightly controlled particle size range, it will provide significantly higher sheet gloss than other calcium carbonates. Additionally, Magnum Gloss® 72% can provide improvements in gloss, opacity, brightness, ink receptivity and runnability on the coater – all of which combine to make this a clearly exceptional product.

Magnum Gloss® 72% is available in truck or rail from our plant in Ste. Genevieve, MO. Alternate packages are available for trial purposes.

There are three types of Magnum Gloss® Powder manufactured at our plant in Ste. Genevieve, MO:

  • Magnum Gloss® SD PCC
  • Magnum Gloss® M PCC has enhanced Hegman grind, oil absorption and particle size characteristics
  • Magnum Gloss® XF

All products are available to be shipped via rail or truck. Magnum Gloss® powder products are also available in 50# bags packaged in Ste. Genevieve, MO. Special packaging and/or bulk bags can be accommodated through one of our packaging partners.


Magnum Fill® Slurry PCC

The Mississippi Lime Magnum Fill® PCC family of slurry products is designed for both paper filling applications and as an extender pigment for coatings. As a filler in paper, it provides high brightness, good opacity and excellent drainage. In paper coatings, outstanding ink receptivity and exceptional brightness properties are obtained. In other coatings, Magnum Fill® will provide excellent hide, brightness and blue-white shade for clearer, brighter colors.

There are four types of Magnum Fill® slurry products manufactured at our plant in Ste. Genevieve, MO.

  • Magnum Fill® 50% Stabilized PCC is a high opacity, high oil absorption product designed for paint applications.
  • Magnum Fill® 65% PCC is a high solids, high opacity functional filler in paper applications.
  • Magnum Fill® 65% Stabilized PCC is a high solids functional filler in paint applications.
  • Magnum Fill® 70% PCC is designed to be an effective filler typically used in precoat applications.

Magnum Fill® Slurry products are available in truck or rail from our plant in Ste. Genevieve, MO. Alternate packages can be supplied for trial purposes.


Magnum Fill® Powder PCC

The Mississippi Lime Magnum Fill® PCC family of powder products are designed as (1) an extender pigment for coatings where it provides excellent hide, good blue-white shade and a high Hegman grind, and (2) as an outstanding filler pigment for paper applications where it provides good opacity as well as excellent retention and drainage properties. All Magnum Fill® powder products are versatile pigments for TiO2 extension in both paper filling and coating applications. Magnum Fill® products are available with higher oil adsorption for increased opacity and wet hide.

There are four types of Magnum Fill® powder products manufactured at our plant in Ste. Genevieve, MO.

  • Magnum Fill® SD is a functional filler with good opacity and optical properties.
  • Magnum Fill® M is a product that is further processed to improve the physical characteristics such as particle size and Hegman grind/dispersability.
  • Magnum Fill® SDL is a light density product that is excellent for paper filler applications. This product also has high oil absorption characteristics for benefits in paint and coatings.
  • Magnum Fill® HO97 is a product with unique morphology that provides excellent opacity and hide in both paper and coating applications.

All products are available to be shipped via rail or truck. Magnum Fill® Powder is also available in 50# bags packaged in Ste. Genevieve, MO. Special packaging and/or bulk bags can be accommodated through one of our packaging partners.
