Made of stainless steel and consisting of a cylindrical bar wound with stainless steel wire, these spiral bar coaters are used to apply a predetermined thickness for coatings with high levelling characteristics.

• A wide range of different wire diameters provides a range of measures for coating thicknesses from 4 to 500µm (0.157 to 19.685mils).
  
  
• 2 standard bar widths are available,140mm (5.5”) or 250mm (9.8”), allowing the user to apply the correct film width dependent on the substrate or test chart width. Other widths are available on request.

   Ideal for use with the Elcometer 4340 Motorised Film Applicator.
