Short answer
Start with a defined target such as substrate wetting or surface slip, then screen grades intended for the formulation. Validate the applied film and any later recoating, printing or bonding steps.
Technical explanation
Wetting and final surface behavior concern different stages of film formation. Research on PDMS-based surfaces distinguishes static and dynamic wetting and shows why one contact-angle observation cannot describe every aspect of surface behavior. These model surfaces should not be treated as direct performance evidence for a formulated coating. [1]
Practical considerations
Keep the binder, substrate and application method fixed. Include a control and use the supplier's grade-specific trial guidance.
