Roof coatings

Elastomeric roof coatings help to protect and seal the underlying roofing material, stop and prevent leaks, and limit future weathering. Omya’s lightweight fillers reduce the weight of the roof coating. They also improve performance in terms of heat reduction, improving the energy efficiency of the building, and in terms of solar reflectance.

Industrial coatings

Industrial coatings protect valuable surfaces against adverse environmental conditions while improving aesthetics. Calcium carbonate is widely used in primers and is also suitable for topcoats, where high gloss and considerable gloss retention as well as low haze are required.

Powder coatings

In powder coatings, Omya mineral fillers support the creation of a coating’s volume. They help to adjust gloss levels, support anti-corrosion properties and improve coating economics.

Plasters and renders

Omya calcium carbonate fillers offer high brightness and the right PSD to allow texturizing to meet aesthetic demands, as well as specific characteristics to achieve crack resistant products with good sanding properties.

Printing inks

Omya calcium carbonates are used as extenders and white pigments. They allow printing of opaque white films. Some specific products allow to increase the solid content without affecting the color place.

Improving sustainability in paint manufacturing at same performance level 

Omya natural minerals help customers meet sustainability targets without compromising quality or performance.  Omya functional fillers are mainly based on calcium carbonate, a natural mineral with low environmental impact. Paint producers can reduce the amount of white pigment, binder and other ingredients in the formulation, lowering the related carbon footprint and reducing the formulation cost.

Your questions answered

Calcium carbonate offers several benefits as a functional filler. It is a natural and renewable raw material that has a substantially lower carbon footprint than other fillers. Selecting the right Omya calcium carbonate filler can enhance opacity, improve bulk stability and control gloss or sheen. Our range of mineral fillers enables paint manufacturers to adjust formulation performance, reduce carbon footprint and manage costs.

Calcium carbonate is a naturally occurring mineral and is generally not subject to energy intensive processing steps, giving it a substantially lower carbon footprint than other fillers. Read more about the use of calcium carbonate to improve sustainability  

Paint manufacturers can realize significant cost savings and sustainability improvements by adjusting the ratio of titanium dioxide to calcium carbonate in their paints. Whilst titanium dioxide is delivering key optical properties, calcium carbonate can be used as a partial replacement to enhance paint properties, manage formulation costs and reduce the related carbon footprint. Learn more about improving performance of your decorative paints with Omya’s range of fillers

Lightweight fillers will reduce the density of the final paint, leading to a higher coverage rate. This means that less material will be needed to cover the same area, or alternatively yield can be increased from the same amount of material, doing more with less.

LWF will reduce thermal conductivity and increase solar reflectance. Both will lessen heat build-up leading to energy savings for cooling.

The introduction of LWF as a replacement for mineral fillers will enhance the overall elongation / flexibility based on the sphericity of the LWF.
