Information Regarding Surface Modifiers

Click For Summary
SUMMARY

The discussion focuses on the search for surface modifiers that create wetting discontinuities in capillary tubes. The user inquires about the 3M coating "FC-723," which is confirmed to be discontinued, and seeks information on its alternative, "EGC-1702." The goal is to compile a table detailing various coatings and their respective contact angles with water droplets. Participants are encouraged to share insights on available coatings and relevant research papers.

PREREQUISITES
  • Understanding of capillary flow dynamics
  • Familiarity with surface coatings and their properties
  • Knowledge of contact angle measurement techniques
  • Basic principles of chemical engineering
NEXT STEPS
  • Research the properties and applications of EGC-1702 as a surface modifier
  • Investigate alternative coatings that produce wetting discontinuities
  • Learn about contact angle measurement methods and their significance
  • Explore academic papers on surface coatings and their effects on fluid dynamics
USEFUL FOR

Mechanical engineers, chemical engineers, researchers in fluid dynamics, and anyone involved in the study of surface coatings and their interactions with liquids.

Hi everyone,

I am doing research on flows in capillary tubes with wetting discontinuities, and I am needing to find some information on coatings that can produce these wetting discontinuities. I have come across some papers that mention a 3M coating "FC-723", and I was wondering if anyone knew of details regarding this coating, or if anyone knew where I could find information on other, similar coatings. In the end, I would ideally like to have a table with several different coatings, and, for example, the contact angle of a water drop that is placed on a surface which has these coatings. Thanks in advance!

*edit* this might be better off in the chemical engineering forum, but since I'm a ME, I figured i'd try here first. :)

Well, it has come to my attention that this chemical FC-723 is no longer produced, but that there is a similar chemical, EGC-1702. Anyone have any information?
