Use of Calcium Carbonate In Paint & Coating Industry
Wall paints for interior and exterior use with their colorful and qualitative diversity enrich our daily lives. Environmentally friendly, water-based paints in new construction and renovation projects create a wealth of design potentials.
YAMUNA CALCIUM® is an important white pigment extender for the economical formulation of dispersion paints for interior and exterior use. The same applies to its use in mineral finishing plasters, to which as a processing aid it also imparts a high degree of pliability. Opacity (wet and dry), brightness, hue, matte or gloss, wet abrasion resistance, rheology and workability are
important properties of dispersion paint.
YAMUNA CALCIUM® has been successfully helping to optimally tune these properties in dispersion paints for many years. Optimizing manufacturing costs is an ongoing issue for paint producers. Thanks to its special properties, YAMUNA CALCIUM® allows for partial replacement of titanium
dioxide pigments and thus significant cost reductions, while maintaining at least the same paint
quality.
Applications in Paint and Coating Industry
1) Extender Pigment: Calcium carbonate acts as an extender pigment, which means it is used to extend or increase the volume of the paint without significantly affecting its properties.
2) Fillers: It serves as a filler material, enhancing the paint's opacity and reducing the amount of expensive primary pigments needed.
3) Rheology Modifier: CaCO₃ helps in modifying the rheological properties of paint, such as its flow and viscosity, improving its application characteristics.
4) Gloss Control: It is used to control the gloss level of paints, providing a range from matte to high gloss finishes.
5) Whiteness and Brightness: Calcium carbonate contributes to the whiteness and brightness of paints, making them look more vibrant and appealing.
6) Durability: It enhances the durability of the paint, providing better weather resistance and longevity.
Advantages of Using Calcium Carbonate
Cost-Effective: It is an economical option compared to other pigments and fillers, which helps in reducing the manufacturing cost.
Versatility: Available in various particle sizes and grades, it can be tailored to meet specific requirements of different types of paints and coatings.
Enhanced Properties: Improves the mechanical properties of the paint, such as hardness, scrub resistance, and durability.
Types of Paints and Coatings Using Calcium Carbonate
Architectural Paints: Widely used in interior and exterior paints to improve opacity and reduce costs.
Industrial Coatings: Used in various industrial applications to enhance the durability and performance of coatings.
Automotive Coatings: Utilized in automotive paints for its ability to improve surface properties and reduce production costs./p>
Powder Coatings: Employed in powder coatings to provide better flow and reduce gloss levels.
Marine Coatings: Helps in improving the anti-corrosive properties of marine coatings.
