Abstract
Methods of applying a polymer coating to a substrate are disclosed. By disrupting a bank of polymer precursor, a smooth coating of fast setting polymer can be applied to a substrate. Apparatus for applying a polymer coating is also disclosed. In one embodiment, an oscillating dispenser is used to apply polymer precursor onto to a dispersive surface. The polymer precursor flows down the surface and is transferred to a moving web. Flowing solvent downwardly through the dispenser can provide efficient cleaning without the need for disassembly or production delays.
