Abstract:

A substrate is rotated at a first bead of less than or equal to 500 rpm per second. A coating composition solution is applied to the substrate at this point. The substrate is then accelerated at a first rate of between 300 and 1200 rpm per second. When the speed of the substrate reaches approximately 3000 rpm per second, a second acceleration is initiated at a second rate of greater than or equal to 3000 rpm. The coating composition is set and the substrate is decelerated. This process provides a more conformal coating of the composition providing better push-pull unwritten variability.
