Abstract
A strong interaction between titanium dioxide and zinc oxide in latex paints has been recognized for decades, yet the harmful consequence of this interaction—paint instability—remains an issue for many coatings manufacturers. An investigation into the chemical and physical changes that occur during paint aging has revealed the mechanism of this instability. The role of the TiO2 pigment grade was further explored, providing an understanding of the gel mechanism and stability performance.
