ChameleoBoost Technology

Unique technology to optimize opacity, balance formulation cost and reduce carbon footprint.

Omya’s ChameleoBoost Technology offers paint and coatings manufacturers a unique way to manage the balance between formulation cost and performance, whilst reducing carbon footprint.

Customers can enhance opacity at equal or reduced formulation cost, whilst maintaining paint properties both above and below critical pigment volume concentration (CPVC).

Alternatively, the partial substitution of titanium dioxide with ChameleoBoost will reduce formulation costs without detriment to performance.

Why is opacity in paints important?

Opacity (hiding power or contrast ratio) in paint refers to its ability to cover underlying surfaces or colors. High opacity ensures effective coverage, requiring fewer coats and saving time.

Costs and carbon footprint: try the ChameloBoost innovation

Titanium dioxide (TiO2) is one of the most effective opacifiers and is widely used in many coatings applications.


However, although it provides outstanding opacity and high brightness, TiO2 is also a key contributor to cost and carbon footprint in many paint formulations.


Finding ways to reduce formulation cost and carbon footprint without compromising performance was a key driver in the development of Omya’s unique ChameleoBoost Technology.


Choose ChameleoBoost for your specific needs

Omya’s decades of experience in mineral chemistry and paint formulation, combined with our high-quality raw materials, led to the development of ChameleoBoost.


This unique technology uses innovative mineral fillers to boost performance, optimize cost and reduce carbon footprint of a wide variety of coatings formulations.

Benefits of ChameleoBoost Technology

  • Enhanced coverage at equal or reduced formulation cost
  • Suitable for matt, semi-matt, semi-gloss and high gloss paint systems
  • Delivers high brightness and enhances titanium dioxide performance
  • Significantly reduces the carbon footprint of the coating formulation
  • Available as powder or slurry in a range of grades

A more sustainable paint manufacturing

ChameleoBoost Technology reduces the carbon footprint of a paint formulation while maintaining its key properties.


Omya’s 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.
