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