Rheology For CoatingsPCI Mag
Mar 10 2006 · For coatings product behavior under very different sets of conditions must be well understood and controlled in order for the product to be successful. A coating for example must be stable during storage easy to apply using whatever application process is appropriate and ideally the final surface finish should be smooth and drip-free.
