Minerals Used for Ink and Pigments

Inks and pigments rely on high-quality minerals to enhance their performance, stability, and application properties. At Ashok Minerals, we supply essential raw materials like Talc, Calcium Carbonate, Calcined Kaolin, and Mica, which contribute to ink viscosity control, color enhancement, and smooth application. Below is a detailed look at each mineral's chemical properties and uses in ink and pigment formulations.

1. Talc

Chemical Properties

• Chemical Formula: Mg₃Si₄O₁₀(OH)₂
• Hydrophobic and chemically inert.
• Platy structure improves dispersion and smoothness.

Uses in Inks and Pigments

• Enhances ink opacity, printability, and smooth application.
• Prevents pigment settling, improving stability.
• Contributes to water-resistant ink formulations.

How Talc is Used in Inks and Pigments

Talc is used to modify ink viscosity, ensuring even distribution of pigments and smooth application. Its natural hydrophobic properties make it ideal for water-resistant inks.

At Ashok Minerals, we supply high-purity talc that ensures optimal performance in ink production.

2. Calcium Carbonate (Calcite) – Precipitated, Coated, and Ground

Chemical Properties

• Chemical Formula: CaCO₃
• High brightness and fine particle size.
• Neutral pH, ensuring compatibility with ink formulations.

Uses in Inks and Pigments

• Increases opacity and whiteness in inks.
• Acts as a cost-effective filler while improving ink viscosity.
• Enhances pigment dispersion, preventing clogging in printing processes.

How Calcium Carbonate is Used in Inks and Pigments

Precipitated Calcium Carbonate (PCC) is used in high-quality inks for its controlled particle size and brightness, while Ground Calcium Carbonate (GCC) provides cost-effective pigment dispersion and viscosity control. Coated Calcium Carbonate further enhances ink performance by improving dispersion.

Ashok Minerals offers Precipitated Calcium Carbonate (PCC), Coated Calcium Carbonate, and Ground Calcium Carbonate (GCC) to meet different ink and pigment formulation needs.

3. Calcined Kaolin (China Clay)

Chemical Properties

• Chemical Formula: Al₂Si₂O₅(OH)₄
• High refractive index, providing opacity.
• Chemically stable with excellent dispersion properties.

Uses in Inks and Pigments

• Improves ink coverage and print sharpness.
• Enhances adhesion, preventing smudging and fading.
• Used in both water-based and solvent-based inks.

How Calcined Kaolin is Used in Inks and Pigments

Calcined Kaolin undergoes thermal treatment to increase brightness and opacity, making it ideal for high-quality printing inks and coatings. It prevents pigment agglomeration, ensuring uniform application.

At Ashok Minerals, we provide high-quality Calcined Kaolin that ensures superior performance in ink formulations.

4. Mica

Chemical Properties

• Chemical Formula: KAl₂(AlSi₃O₁₀)(OH)₂
• Layered, reflective structure for pearlescent effects.
• Chemically inert, offering long-term stability.

Uses in Inks and Pigments

• Provides metallic and pearlescent effects in specialty inks.
• Enhances smoothness, preventing clogging in printing equipment.
• Improves ink durability against environmental factors.

How Mica is Used in Inks and Pigments

Mica is commonly used in specialty inks for metallic and pearlescent effects. It enhances gloss, improves ink adhesion, and provides a unique shimmer in coatings and printing applications.

Ashok Minerals supplies high-purity mica for ink and pigment manufacturers, ensuring consistent quality and performance.
