Princeton Catalyst Polytip Bristle Brushes are another Princeton breakthrough that advances the science of synthetic fiber technology. For the first time, the tip of each individual fiber has been split to replicate the natural flags that are present in the finest natural bristles.
By giving each fiber two to three distinct tips, Polytip bristles are able to hold a higher volume of paint while providing smoother application. These paintbrushes are super stiff yet still extremely responsive.
Designed for use with medium- to heavy-body acrylics and oil paints, Catalyst Brushes push even heavy gel mediums with assurance. Unlike natural hog bristles, which can be rendered useless when water-soaked, Catalyst Brushes maintain excellent integrity in water.
