3.7. Impact of the state of water on tablet sticking (Met granulates produced with VA64 and PVP)
Sticking refers to granulate adhesion to the punch and die surfaces, with powder moisture having a significant impact on sticking. Tablet sticking is estimated by measuring the scraping force [8] and [33], which is the force required to scrape the tablet off the punch face; scraping force increases with increasing sticking [17].
