Paints and coatings

The calcium carbonate is widely used in paints, both as a filler and as a titanium extender. In this way, it enhances the paint’s characteristics and reduces the cost of the formula. Chemically stable (except in acidic environments), it can be used in a wide range of systems. It also helps regulate paint pH. Natural and recyclable, calcium carbonate helps reduce the environmental impact of paints.

Benefits

Whiteness and dry hiding power

Calcium carbonate is one of the whitest fillers used in paints. It thus confers high levels of whiteness to the paints in which it is used. In high-CPV paints, it provides excellent opacity and reduces the amount of titanium dioxide required, thanks to its "dry coverage" effect.

Titanium extender

Certain innovative ultra-fine calcium carbonates enable a "titanium spacer" effect to be achieved. The spacing of titanium dioxide (TiO2) particles optimizes their opacifying effect and increases the paint's dry and wet coverage. This reduces the amount of TiO2 required and thus the cost of the formula, without compromising paint quality.

Rheology

Calcium carbonate directly influences paint rheology. It helps to obtain the desired consistency, which facilitates application and improves paint texture for a better finish.

Mattifying effect, shine control

The choice of calcium carbonate helps control paint gloss. In the case of matt paints, the use of calcium carbonates with a narrow particle size distribution provides a very good matting effect.

Reducing environmental impact

Calcium carbonate is a natural, inert (except in acidic environments) and non-toxic material. Environmentally friendly, it helps reduce the carbon footprint by reducing the use of TiO2. Certain carbonates are considered as recycled materials under ISO 14021, and can therefore help increase the recycled content of finished products.

Lower formula costs

The use of calcium carbonate makes it possible to reduce the cost of paint formulas while maintaining a high level of performance.

Architectural paintings

Calcium carbonate is used to adjust gloss and achieve the desired finish. It also helps to increase dry opacity while reducing the formula's carbon footprint. An innovative range of ultra-fine carbonates has been developed. These carbonates act as TiO2 extenders, distancing its particles from one another, thus optimizing dry opacity and wet opacity while reducing the quantity of TiO2 and environmental and financial costs. Provençale SA also offers a range of recycled calcium carbonates (as defined by ISO 14021).

Industrial paints

Industrial paints

Calcium carbonate (CaCO3) is a filler of choice in anti-corrosion paints, thanks to its chemical inertness (excluding acid).

Redispersible powder paints

Redispersible powder paints

The hydrophilic nature of calcium carbonate enables it to disperse rapidly in water, making this filler a must for redispersible powder paints.

Specific and functional paints

An innovative range of ultra-fine calcium carbonates (CaCO3) has been developed. These carbonates act as TiO2 extenders, distancing its particles from one another and optimizing both dry and wet opacity. What's more, the whiteness of CaCO3 makes this filler an ideal candidate for "cool roof" paints, greenhouse shading and tracing paints.)
