Purdy Dale Elite paint brushes are hand-chiseled for easier cutting-in. They have an angled edge and feature a blend of Dupont™ Chinex® and Orel® Polyester solid round tapered filaments. The Purdy Dale Elite's Unique Chinex characteristics allow filaments to self-flag as the brush wears. Orel Polyester added for ideal stiffness retention. The combined result is greater paint lift, smooth application, high abrasion resistance, and significantly faster cleaning. The Purdy Dale Elite is recommended for use with all paints, especially today's high-solid, low V.O.C. paints and heavy-bodied latex coatings that can be more difficult to apply smoothly.
