Gapped Rods - For higher viscosity coatings, gapped rods reduce clogging and eliminate lines.This results in taller raised striations which are affected more quickly by surface tension, and flatten out to a glass-like surface in a shorter time span. Twin-Coat Rods - Another advantage is that a two-wire rod, used instead of a conventional single-wire rod, will have more than twice as many 'grooves' for a given coating thickness.The result is a modified groove between the wires that will produce wet coatings up to 11 mils (.011') thick. A standard single-wire rod is over-wound with a second, smaller wire which follows the spiral of the base wire. Twin & Gapped Drawdown Rods - For those applications where heavier coatings are required, use these special drawdown rods with two wires.Applications: Adhesives, Board, Cellulose, Ceramic Colors, Cosmetics, Driers, Duplicating Inks, Emulsions, Fillers, Floor Polishes, Lacquers, Metallic Powders, Oils, Paper, Photographic Papers, Pigments, Plastics, Printing Inks, Resins, Varnishes, Waxes & Hotmelts.They are manufactured of ground and polished steel and the very finest of wires.Applicator Rods are available in any length, a variety of diameters and almost any wire size.The desired thickness can be repeated again and again with little loss of time and expense.Accurate thickness of coating from fractions of a mil and up can be achieved with this coating method.The groove area is determined by the size of the wire, hence, the larger the wire, the larger the groove.The amount that has passed through flows out or congeals, leaving a smooth, uniform thickness on the substrate. This groove or space allows the right amount of coating to pass through. The coating thickness is governed by the area of the groove between the coils of wire.
