Catalyst™ Polytip™ Bristle

Catalyst™ Polytip Bristle brushes are another Princeton breakthrough that advances the science of synthetic hair. This new series is super stiff yet still extremely responsive. Unlike natural hog bristle, Catalyst™ has real integrity in water. Natural bristle can be rendered useless when it is water-soaked. The true advance in Catalyst™ is the Polytip feature. 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 2 to 3 distinct tips, Catalyst™ is able to hold a higher volume of paint while providing a smoother application. Designed for use with medium to heavy-bodied acrylics and oil paints, Catalyst™ pushes even heavy gel media with assurance. Catalyst™ Polytip Bristle brushes truly are tools that move paint.

As a long time user of natural bristle brushes, I had my reservations about synthetic hair brushes. After trying the Catalyst brushes, I am a convert. When using these brushes, I immediately noticed that they kept their shape while painting, allowing for greater control. These synthetic brush hairs mimic the hairs of natural bristle, but have much greater strength. I can be very hard on brushes with my painting techniques and Catalyst hold much better than natural bristle brushes. The Princeton flats and filberts have long fibers which add greater flexibility to the brushes. The rounds really hold their shape, allowing for greater control of details and mark-making. If you are painting in heavy body acrylics, the Catalyst brushes are great because these brushes keep their properties in water, unlike natural bristles. These brushes are very easy to clean whether you are using oil or acrylic.
