Abstract
A coating is provided for a substrate comprising a polyisocyanate; an amine donor and/or hydroxyl donor; an isocyanatosilane adduct having terminal isocyanate groups and at least one hydrolyzable alkoxy group bonded to silicon; and optionally a polymer selected from the group consisting of polyethylene oxide, polyvinyl pyrrolidone, polyvinyl alcohol, polyethylene glycol, and polyacrylic acid. The coating can accommodate a drug so that when the coating is applied to a medical device, the medical device becomes drug-releasing when in contact with aqueous body fluid. A coated article as well as a method for preparing the coating is also provided.
