Definition of Calcium Carbonate:
Calcium Carbonate mostly referred to as ground calcium carbonate is a paint additive that works to densify the product, acts as an extender or spacer for Titanium di Oxide, and also functions to increase paint gloss or reduce Paint gloss.
General Use of Calcium Carbonate in Paint Production:
GCCs are also referred to as rheology modifiers. This means that they are used to fine-tune the feel and texture of the paint product. Although rheology modifiers do more than just fine-tune. They aid in thickening a formulation and also act as viscosity modifiers. Moreover, rheology modifiers help to prevent sedimentation of the product during transport and storage. since Ground calcium carbonates are referred to as rheology modifiers by substitution it means that they prevent sedimentation of the product during transport and storage. it means they modify Product viscosity, They help in thickening a formulation and as stated earlier they are used to fine-tune the feel and texture of the product.
Special Characteristics of Good Calcium Carbonate:
Good particle size distribution: A good powdered GCC should have a very fine particle size distribution, The best particle size being powder form particle size.
Provide good opacity for your products: GCCs should provide enough opacity/coverage when used in paint production. Paint coverage or Opacity is a vital factor that helps in the aesthetic qualities of paints.
High Brightness (above 96%):
Purity (above 98.5%):
Industrial Guide Usage for Calcium Carbonates in Industries:
In the industrial use of GCC. Especially in paint industries that require the use of calcium in large quantities of up to eight bags or more. there is a need to take special care of the dissolving process of this calcium in liquid to avoid flocculation or congealing. The dissolving is done in large industrial machines with spinning blades that help spread this particle to form a fine liquid mixture.
