Applying solution or suspension based active or polymer via air atomizing spray gun. The process may include application of glidant or other excipient via the precision powder feeder to enhance the rate of spray and/or the amount of solids applied per unit time. Some actives and polymers are adhesive as they dry, applying glidant via the powder feeder can improve spray rates dramatically by mitigating this adhesive nature. In some cases this can allow solid content in solution/suspension to be doubled. Conventionally, glidant may be added to the suspension before spraying. By not adding it to the suspension gun blockage is eliminated, suspension preparation is simple and the process is streamlined.
