This chemical-resistant ox-hair flat artist's brush is excellent for applying conformal coatings. This brush is designed to withstand harsh chemicals, such as toluene, without deteriorating by using a chemical-resistant epoxy to set the ox-hair fill, and an unvarnished hardwood handle that will not peel or flake. Complete with a flat brush shape and a corrosion-resistant nickel-plated ferrule. This 3/8" size brush has a 7/8" trim with a brush face width of 5/8", and an overall length of 7-3/4". This natural-fiber brush is used in a wide variety of applications and ideal for flat even brush strokes using watercolor and tempera.
