Information Regarding Surface Modifiers

AI Thread Summary
Research on flows in capillary tubes with wetting discontinuities is seeking information on coatings that create these effects. The 3M coating "FC-723" was initially mentioned, but it is no longer produced. A similar coating, "EGC-1702," has been identified as a potential alternative. The goal is to compile a table detailing various coatings and their corresponding contact angles for water drops. Additional insights or resources on these coatings would be appreciated.

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?
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
