It needs to be melted onto the surface at extremely high temperatures to make a uniform film. That can't be done on paint. The temperature needed to melt it would ruin the paint. So, the manufacturers purchase the teflon in a suspension. Very small particles of it are suspended in a water/emulsion carrier. This is added to the sealant. So you aren't getting a uniform film, like your cooking pan, you are getting little dots of PTFE that lay on the surface of the paint. The chemical that is holding them in place and making a uniform "sacrificial" layer is the polymer (usually a charged silicone based polymer)
Similar is true with carpet and fabric protectants using a flourochemical bonding process.
