Gordon Brush® offers 4 anti-static acid brushes. All four brushes use horsehair set in a tin tube that is then crimped. One also has a choice of trim length, handle length, brush face width, and body diameter.
Anti-static acid brushes are used in the electronics, plumbing and many other industries to apply glue, or other liquids and [certain] chemicals, and for quick small-area cleaning or wiping applications.
