Paint and Coating Industry caption

Calcium carbonate plays an important role in the paints and coatings industry. It can be used as a filler, an extender pigment, and a functional additive to enhance coating performance, reduce production costs, and impart special properties to coatings. As coating technology continues to evolve, the application prospects of calcium carbonate in the industry are becoming increasingly extensive. Its primary applications include the following:

1. As a Filler

Calcium carbonate is one of the commonly used fillers in paints and coatings. It increases coating thickness and improves opacity, thereby reducing pigment usage and lowering production costs.
Calcium carbonate addition improves the physical properties of coatings, such as hardness, abrasion resistance, and weather resistance.
Calcium carbonate also enhances the application performance of coatings, improving leveling and reducing sagging.

2. As an Extender Pigment

Calcium carbonate can serve as an extender pigment, enhancing the whiteness, gloss, and adhesion of coatings.
Calcium carbonate also improves the corrosion resistance and water resistance of coatings.

3. As a Functional Additive

In certain specialized paints and coatings, calcium carbonate can function as a special additive, such as a flame retardant or an anti-static agent.
The addition of calcium carbonate imparts specific functionalities to coatings, such as flame retardancy and anti-static properties, meeting the needs of different application fields.

4. Application Fields

Calcium carbonate is widely used in various types of paints and coatings across different industries, including:

Construction: Interior wall coatings, exterior wall coatings, floor coatings, etc.
Industrial: Anti-corrosion coatings, marine coatings, automotive coatings, etc.
Wood coatings: Furniture paint, floor coatings, etc.

The calcium carbonate used in paints and coatings includes Diamond Quantum calcium carbonate products such as OT, TDD, and CC, which are characterized by low specific gravity and resistance to settling. OT and TDD are surface-treated with resin acid, while CC is surface-treated with fatty acid, allowing them to meet the requirements of different coating systems.
