GCC meets requirements of paint & coatings industry
Ground calcium carbonate (GCC)
The paint and coatings industry is faced with the challenge of developing high-quality yet economical products that meet both aesthetic and functional requirements. In this context, ground calcium carbonate (GCC) has established itself as an important raw material that offers many advantages in the production of paints, varnishes and coatings in a competitive environment.
What is ground calcium carbonate?

Ground calcium carbonate (GCC) is extracted from natural limestone deposits and ground into a fine powder. The high quality of Cemix calcium carbonate is characterized by its chemical stability, high purity and constant particle size, which makes it an ideal filler and pigment in the paint and coatings industry.

Advantages of GCC in paint & coatings industry

1. improved opacity and whiteness: GCC gives paints and coatings high opacity and brightness. It acts as an opaque filler that improves light scattering and thus increases the opacity of the end products.

2. cost efficiency: As a cost-effective filler, GCC helps to reduce the amount of more expensive pigments, such as titanium dioxide. This lowers production costs without compromising the quality of the paints and coatings.

3. improved rheological properties: GCC positively influences the viscosity and flow properties of paints, making them easier to process and apply. It ensures an even distribution of pigments and helps to prevent sedimentation.

4. increased durability and weather resistance: the use of GCC in exterior paints increases resistance to weathering by improving surface hardness and reducing wear.

5. environmental friendliness: As a natural mineral, GCC is environmentally friendly and can be safely used in ecological paint and varnish systems. It contains no harmful substances and contributes to sustainable product development.

Areas of application for GCC in paint & coatings industry
  • Interior and exterior paints: GCC ensures uniform opacity, improved colour stability and optimized processing properties.
  • Decorative coatings: In decorative paints and varnishes, GCC improves the texture and gives an attractive appearance.
  • Industrial coatings: GCC increases abrasion resistance and mechanical stability in coatings that need to be particularly robust and durable.
  • Powder coatings: GCC is also used in powder coatings to optimize the feel and surface finish.
