Coatings & surface chemistry

Coatings, coating flow and coating adhesion involve multiple phenomena that often result in complex processes and complicated behaviors. Shear and extensional rheology can be equally important in the actual coating process, but often mass-transfer for solvents and heat and cooling rates also play a part, as well as the surface chemistry and how the surface interacts with the coating.  In addition, coating molecularly thin layers involves understanding the surface chemistry and tools required to create robust layers and activations.  The balance between all of these phenomena, and the manner in which they evolve, will strongly influence your outcomes.  Although often one might consider coating flows as being large-scale industrial applications and printing and web coating, these processes play a significant role in less obvious applications.  For example, drug-eluting stents can be coated using a roll-method, and thin films can be made in this manner.  By leveraging CPG's broad expertise to gain a complete understanding of a procedure's physics and sensitivity to conditional variations, our clients are able to maximize the potential utility of new materials and products.  In addition, changing the surface chemistry of your material can greatly enhance adhesion or functionality, and through our partner at PlasmaTreat ( we can provide the concept-to-production service you require to maximize your product's performance.
