Super fine CaCO3 white stone powder in paint production

Superfine white limestone powder CaCO3 is a common ingredient in paint production, milled from natural white stone. The main chemical components of ultra-fine white limestone powder are CaCO3, with very small amounts of impurities such as Fe2O3, MgO, SiO2, Al2O3, and others. In the paint production industry, high whiteness and fineness are required for CaCO3 powder, along with good adhesion properties.

Requirements of stone powder for paint

Super-fine CaCO3 stone powder is used as an inorganic filler in paint manufacturing. The quality of paint depends on the whiteness and fineness of the stone powder used.

Water-based paints and oil-based paints must have the following characteristics:

– Adhesion strength, smoothness

– Especially excellent dispersion ability

– The calcium carbonate powder from Đức Thịnh is produced by a modern factory with advanced technology, achieving super fine and bright quality for the paint industry that meets international standards.

Application of Superfine CaCO3 limestone powder in the paint manufacturing industry.

In the paint industry, limestone powder is used as a major component, accounting for up to 60% of the total composition. Limestone powder used in paint exhibits excellent brightness, low oil absorption, good dispersion, environmental durability, low abrasiveness, low shrinkage, and stable pH level. In addition, it also has the advantage of enhancing the corrosion resistance properties in natural environments and improving the necessary viscosity for paint products.

Applications of stone powder in paint production

• Stone powder is the main filler in the coating industry, also known as Calcium powder. Fineness, size and particle distribution of Calcium Carbonate affect light opacity during coating process.
• In some exterior paint formulas, stone powder provides weather resistance and pH stability while enhancing adhesion and appearance.
• The application of stone powder in road marking and traffic paint helps improve durability and reduce shrinkage.
• Stone powder is combined to provide Cog brightness and opacity, as well as to reduce costs.
• White electrostatic paint with a high content of TiO2 can benefit from using stone powder as a filler.
• Elastomeric roof coating utilizes pigments for brightness and opacity, and stone powder can help enhance these optical properties.
• Stone powder is an extender pigment in various types of printing inks, providing opacity, viscosity, and gloss control. They are also used as colorants and aid in dispersion.
