Optimization of Fluid Coating
- Published: October 17, 2014
Developing a product in the fluid coating industries requires determination of raw materials to provide for the differentiated features of the product, but equally important is the process development associated with turning these raw materials into an effectively and efficiently produced item. Whether you are looking to develop an improved tape, label, battery, or optical film, understanding and optimizing the coating process is important. The larger this coating window the more latitude there is for success.
