I want to make a coat my polyurethane slides with a coating that will make them more hydrophobic. I've seen people use fluorosilanes on silicone and glass but wasn't sure if this would translate to polyurethane as well.
(3-glycidoxypropyl) trimethoxysilane has been used to enhance the adhesion properties of PU.
Yes you can. Contact the silane manufacturers and they will prescribe the right silane.
You can pre-treat the PU surface by plasma treatment to activate the surface and them deposit organosilicon coating by plasma enhanced chemical vapor deposition PECVD. For example hemamerhyldisilixane. You may look to there publications ( see beliw)

Yes you can
Either add A1100 Silane to the PU or coat it with 20%water/ 80%IPA / 2% A1100 and dry it at 60-80 C for 1 hr.
