Collection: Princeton Catalyst 6400 Long handle Brushes
The Catalyst 6400 Polytip Bristle Brushes by Princeton redefine synthetic brush performance. Engineered for medium to heavy-bodied acrylics and oil paints, these brushes combine unparalleled stiffness with exceptional responsiveness. Thanks to the Polytip design—each filament split into 2–3 tips—they replicate the flagging of natural bristle, resulting in outstanding paint hold and a smooth, controlled release.
Choose from a wide range of shapes and sizes to suit your technique. Smaller sizes are perfect for detail and precision, while larger brushes deliver expressive strokes and coverage for larger compositions. These brushes also excel in palette knife-style painting, heavy impasto, and scraping techniques.
