ChameleoBoost by Omya offers a unique solution for boosting opacity while optimizing formulation cost. ChameleoBoost will either enhance coating performance (e.g. opacity) at equal formulation cost or reduce formulation cost (e.g. partial substitution of titanium dioxide) while maintaining performance level of the coating film. Any combination of the two is of course possible as well.
In general terms, opacity can be described as the ability of a substance or mixture to hide a substrate. A typical example would be a coating film covering a given surface such as a wall. This simple phenomenon is actually the result of a rather complex interplay of various components and parameters. In industry, opacity is often referred to using other terms such as contrast ratio or hiding power. Whatever term is used, the common functionality they describe is the ability of an applied optical layer to hide what is underneath.

Key Factors Influencing Opacity:
  • Amount and type of titanium dioxide
  • Volume and type of mineral filler varying in composition, particle size and shape
  • Pigment volume concentration
  • Spreading rate
  • Film porosity
