Made of B-500 repositionable vinyl cloth material, our WM series wire markers are able to withstand moderate heat, oil and dirt. Labels hold tightly to the wire due to their high adhesion properties and can be re-used with ease if repositioning is required. Brady B500 is a polymer coated cloth with a printable topcoat and a rubber based pressure-sensitive adhesive. - Card-mounted wire markers are sold as individual characters or as consecutive numbers and letters or as 16 different solid NEMA colors. B500 has excellent flexibility for wrapping around curved surfaces. Brady B500 has good oil and water resistance and good print durability.
