Garamite® mixed mineral thixotropes (MMTs) can help with key properties such as sag resistance and settling resistance while maintaining a reasonable package viscosity.
As regulations call for lower VOC levels, it becomes increasingly difficult to design coatings with appropriate rheology. Properties such as sag resistance and settling resistance become more difficult to balance with package viscosity. The use of Garamite® mixed mineral thixotropes (MMTs) can help with key properties such as sag resistance and settling resistance while maintaining a reasonable package viscosity.
This article explains how and why Garamite works. MMTs are compared to various thixotrope technologies used in different types of industrial coatings, including high-solids epoxies, low-HAPs systems, high-solids alkyds, chain-stopped alkyds and zinc primers. Also discussed are methods of incorporation and other processing considerations.
