A small, precision air motor spins a dispersion cup, which inserts into the bore. A metered amount of material is released into the cup to evenly coat the inner surface of the bore. The dispenser cup prevents overspray and applies a uniform, controlled bead of adhesive. The RotoCoater can be used with just about any liquid material and dispenses a controlled bead to any size or shape recess.
