Abstract
A flexible, lubricious organic coating is formed by applying a mixture of an isocyanate, a polyol, polyvinylpyrrolidone (PVP), and carrier liquid to a surface to be coated. The carrier liquid is removed and the mixture reacted to form a lubricious, flexible coating, particularly suitable for use as a protective lubricious coating on medical devices introduced into the body. The coating exhibits a significantly reduced coefficient of friction when exposed to water or aqueous solutions.
