Grounded Calcium Carbonate (GCC) Powder Supplier in India

GCC is made by mechanically grinding natural limestone into a fine, white, odorless powder. Unlike precipitated calcium carbonate, which is chemically synthesized, GCC keeps the natural crystalline structure of the limestone it’s ground from — which is part of why it performs so consistently as a filler and performance additive across industries. As a GCC manufacturer, our job comes down to controlling three things closely: particle size, brightness, and moisture — because those three variables are what determine how the powder behaves once it’s in your product.

What is Grounded Calcium Carbonate (GCC)?

Grounded Calcium Carbonate (GCC) is obtained by mechanically grinding natural limestone. It is a white, odorless powder widely used as a filler and performance enhancer in many products. As an experienced Grounded Calcium Carbonate (GCC) Manufacturer in India, we ensure our GCC offers high brightness, controlled particle size, and low moisture content, making it ideal for industrial use.

Paints and coatings

GCC is commonly used to extend titanium dioxide, improving dry-film opacity and scrub resistance without inflating cost. Our higher-brightness grades are built specifically for this.

Paper and pulp manufacturing

As an alkaline filler, GCC increases brightness and opacity while reducing dependence on wood pulp — useful both for cost and for sheet smoothness in high-speed printing.

Plastics and PVC Applications

GCC is used as a functional filler in PVC compounds and masterbatches, improving stiffness, impact strength, dimensional stability, and surface finish cost-effectively.

Adhesives and ceramics

GCC reinforces rubber compounds by improving tear strength, elasticity, durability, and shrinkage control, making it ideal for demanding industrial applications.

Rubber and sealants

GCC enhances bonding strength, reduces shrinkage, and improves surface finish, helping produce high-quality adhesives, ceramic tiles, and sanitary ware.

Construction materials

GCC improves the density, strength, workability, and long-term durability of concrete, cement, mortar, and other construction materials for reliable performance.
our manufacturing process​ Grounded Calcium Carbonate Powder

Our Manufacturing Process

Limestone is mined, cleaned, and fed into automated grinding systems paired with air-classification technology that separates particles by size. This is what lets us hold tight particle-size control across a batch, rather than producing a wide, inconsistent range.Every batch then goes through multi-stage quality checks—brightness, moisture content, particle size distribution, and chemical composition—before it’s cleared for packing. We pack into bulk tankers, jumbo bags, or standard moisture-resistant bags depending on the order, matched to how the customer plans to handle and store it. Our streamlined production process, advanced equipment, and experienced quality team ensure consistent product performance, reliable supply, and compliance with industry standards for every shipment.

GCC Powder Applications by Industry

Paint and Coating

Our high-whiteness GCC powder replaces titanium dioxide, boosting dry-film opacity, scrub resistance, and weather durability in industrial and decorative paints.

Plastic Industry

An essential functional filler for PVC and masterbatches that enhances tensile strength, impact resistance, thermal conductivity, and surface smoothness.

Paper Industry

Premium alkaline filler replacing expensive wood pulp to maximize paper brightness, opacity, sheet smoothness, and high-speed print ink absorption.

Rubber Industry

An efficient reinforcing agent that improves tear strength, elasticity, and processing behavior while reducing shrinkage in heavy-duty rubber products.

Grade Particle Size Brightness Primary Use
Sigma Ultra-Fine Up to 2 Microns 96% – 98% Premium Paints & Coatings
Sigma Fine-Coat 2–5 Microns 95% – 97% Plastics & PVC Masterbatches
Sigma Industrial 300–500 Mesh 80% – 93% Rubber, Paper & Adhesives

Why Choose Sigma Minerals for GCC Powder

Three things tend to matter most to the industries we supply: whether the spec holds steady batch to batch, whether delivery happens on the date agreed, and whether we can adjust a grade to a specific application rather than pushing one standard product on everyone.

We source directly from Rajasthan’s limestone reserves, which keeps both our supply chain and pricing more predictable than manufacturers sourcing raw material from farther away. Combined with in-house testing on every batch, that’s the foundation the rest of the relationship is built on — for customers ordering 25 kg bags and for the ones ordering by the tanker load.

Why Choose Sigma Minerals?
