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 1/4" size brush has a 3/4" trim with a brush face width of 1/4", and an overall length of 7-1/2"
