Information Regarding Surface Modifiers

[MJCfromCT]

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?

Hello,

Thank you for sharing your research topic with us. From my understanding, surface modifiers are materials that are applied to surfaces to alter their properties, such as wetting behavior. The 3M coating "FC-723" is a fluoropolymer coating that is commonly used for its non-stick and low friction properties. It is typically used in applications where there is a need for chemical resistance, high temperature resistance, or low surface energy. However, I am not sure if this specific coating can produce wetting discontinuities.

To find more information on this coating and other similar coatings, I would suggest reaching out to 3M directly or searching for academic papers that have used this coating in their research. Additionally, you can also try contacting other researchers in the field or attending conferences to learn more about different coatings and their properties.

I am not sure if there is a comprehensive table that includes different coatings and their contact angles with water drops, as the contact angle can vary depending on the surface roughness and other factors. However, you can find information on the contact angle of different coatings in academic papers or by conducting your own experiments.

I hope this helps and good luck with your research!
