METHOD FOR PROVIDING A HYDROGEL COATING

摘要

The present invention relates to a method for providing a hydrogel coating on a polymeric substrate of a medical device comprising: a priming step wherein the polymeric substrate is contacted with a priming solution comprising 1 to 30 wt % of a polyethylene glycol diacrylate having an average molecular weight of 300 to 750 Da; a grafting step following the priming step wherein the polymeric substrate is contacted with a grafting solution, thereby providing a polymeric substrate of a medical device having a hydrogel coating.
