I would suggest looking into brushable urethane. 1114 used it on their rollers in 2014....

Just so nobody gets the wrong idea about the paint on urathane I wouldn't mind commenting on this. Yes we did use this for our intake rollers in 2014 (also 2012 and 2011), and it served us well. Although we replaced the rollers more then you might think. I believe we changed them every day almost, so it might not be as reliable or durable as you think.

Was it the urethane material itself or the bond between the urethane and PVC that was failing? And if it's the latter, could you detail how you prepped the roller surface before applying the urethane?

I believe it was the bonding into the PVC rollers that would start to peel off once it got a cut out hike in it. I want apart of the people who made them all the time, but I believe they cleaned each one with rubbing alcohol before applying.
