Paint Industry
High-purity natural micronized calcium carbonate as a functional filler for the paint industry. 10 product grades from AY 103 to AY 780, covering particle sizes between 1 and 80 microns.
Calcium Carbonate in the Paint Industry
Micronized calcium carbonate (CaCO₃) is one of the most widely used functional fillers in the paint industry. In paint formulations, it optimizes production cost while directly influencing performance properties such as opacity, whiteness, gloss, and surface quality.
At Aydın Madencilik, we produce natural micronized calcite at our Bursa Gemlik facility using German Hosokawa Alpine technology. Our product range covers a wide spectrum of paint applications — from interior and exterior wall paints to industrial coatings, primers, putties, and powder coating formulations — supplied to manufacturers across Turkey, Europe, and global export markets.
Interior and Exterior Wall Paints
In interior wall paints, fine-particle calcium carbonate supports both the opacity and matte appearance of the paint film. Our fine grades such as AY 103 (3 µm) and AY 106 (6 µm) are preferred in interior paint formulations thanks to their smooth surface texture and high whiteness values.
For exterior wall paints, weather resistance and low water absorption are critical. Our AY 210 (10 µm), AY 215 (15 µm) and AY 320 (20 µm) grades are used as functional fillers in exterior paints, reducing water absorption and contributing to long-lasting weather-resistant coatings.
Primer and Putty Production
In primers and putties applied prior to painting, calcium carbonate is the core filler of the formulation. Our coarser grades such as AY 560 (60 µm) and AY 780 (80 µm) deliver high filler loading capacity in putty production while maintaining processability. These products enable smooth substrate preparation and improved paint adhesion across both decorative and industrial applications.
Powder Coating Applications
In powder coating formulations, calcium carbonate plays a critical role in flow improvement and cost control. Our AY 107 (7 µm) and AY 108 (8 µm) grades, with their narrow particle size distribution, support homogeneous mixing and consistent film build in industrial and architectural powder coatings.
Industrial and Protective Coatings
In industrial paint production, calcium carbonate serves as a supporting functional filler in formulations engineered for corrosion resistance and mechanical durability. Our AY 327 (27 µm) grade, with its controlled particle size distribution, offers ideal performance in heavy-duty industrial and protective coating systems.

Paint Industry Frequently Asked Questions
What is calcium carbonate used for in the paint industry?
Calcium carbonate (CaCO₃) is the most widely used functional filler in paint formulations. It enhances opacity, provides a matte appearance, regulates viscosity and optimizes production cost. As a filler, it is critical in interior wall paints, exterior wall paints, industrial coatings, primers, putties and powder coatings.
Which micron size of calcite is used in interior wall paint production?
Fine-particle calcium carbonate is generally preferred for interior wall paints. A fine micron value enables the paint to form a smooth surface and deliver high opacity performance. Aydın Madencilik’s AY 103 (3 µm) and AY 106 (6 µm) grades are ideal for interior paint formulations.
Which calcium carbonate products are suitable for exterior wall paint?
Exterior wall paints prioritize weather resistance and low water absorption. Mid-particle-size calcium carbonate is therefore preferred. Our AY 210 (10 µm), AY 215 (15 µm) and AY 320 (20 µm) grades are designed for exterior paint formulations and deliver durable, weather-resistant coatings.
Why is calcium carbonate preferred in putty and primer production?
In putty and primer formulations, calcium carbonate provides volume thanks to its high filler loading capacity and enables smooth substrate preparation. Coarse grades are ideal for these applications. Our AY 560 (60 µm) and AY 780 (80 µm) grades are widely used as base fillers in putty production.
What is the difference between natural and coated calcium carbonate for paint production?
Natural calcium carbonate is produced by grinding and micronizing natural calcite stone and is used as the standard filler in the paint industry. Coated calcium carbonate is surface-treated with stearic acid or similar agents for improved dispersion in polymer matrices — primarily used in plastic and masterbatch applications. For most paint formulations, natural micronized calcite is the optimal choice.
What are the quality standards of Aydın Madencilik's calcite products for the paint industry?
We operate from a 15,000 m² production facility in Bursa Gemlik, Turkey, using German Hosokawa Alpine technology. Every production batch is laboratory-tested for particle size distribution, whiteness value, moisture content and chemical analysis to ensure consistent paint industry specifications. Technical data sheets and samples are provided on request.
What is your logistics advantage for calcium carbonate supply to European paint manufacturers?
Our facility is located in Gemlik, Bursa — at the heart of the Marmara Region industrial corridor. Proximity to Gemlik Port enables direct maritime shipments to European destinations including Italy, Spain, the Netherlands, Germany and the United Kingdom, as well as global export markets. Container, big bag and bulk delivery options are available.
Which calcium carbonate is used in powder coating production?
In powder coating formulations, fine micronized calcite with a narrow particle size distribution is preferred for homogeneous mixing and controlled flow properties. Our AY 107 (7 µm) and AY 108 (8 µm) grades are specifically designed for powder coating applications.
