Accurate solution preparation and mixing processes are mandatory in high-precision, roll-to-roll coating operations. To ensure success, the liquid fed to an applicator must be homogeneous in composition, properties and temperature. Controlling these parameters batch to batch is also very important. Thus having a firm understanding of fluid dynamics and mixing parameters is critical to delivering a uniformly coated product with the expected performance characteristics.

This article details key solution preparation and mixing considerations for scaling up a coated product from small-scale laboratory to production.
