Abstract: The lubricious hydrophilic coatings of the invention are significantly more lubricious when wet than when dry, are adherent to a variety of substrates, and are resistant to removal by wet abrasion. In one embodiment, the coatings include a hydrophilic polyolefin such as polyvinyl-pyrrolidone and a water-insoluble stabilizing polymer such as a cellulose ester. The coatings may also include an adherent polymer and a plasticizing agent. The coating may be applied by preparing a solution of the stabilizing polymer and a solution of the hydrophilic polyolefin, and coating the substrate first in one then the other. Alternatively, both the stabilizing and hydrophilic polymers may be dissolved in a single solvent system and applied to the substrate in a single step. In another embodiment, only a solution of a hydrophilic polyolefin is applied directly to the substrate. In this embodiment, the solution of the hydrophilic polyolefin includes a cosolvent which acts as a solvent for both the hydrophilic polyolefin and the substrate. The coatings of the invention may be applied to biomedical devices and implants such as catheters, condoms, and nasogastric and endotracheal tubes.

Abstract: A coating composition adapted for repairing a damaged coating on a substrate comprises as the binder a mixture of a polyacrylate, an acrylated alkyd resin and a cellulose ester which form 100 percent of the binder. The coating composition is particularly well suited for use in preparing damaged paint on a motor vehicle body. The binder may be mixed with a volatile inert organic solvent for the binder in making the composition. The composition has a higher solids content than composition usually used for repairing damaged coatings and much thicker layers of the coating composition may be applied. By mixing the components of the binder in the ratio of 10 to 60 parts by weight of polyacrylate to 30 to 75 parts by weight of acrylated alkyd resin and 5 to 45 parts by weight cellulose ester to form the binder a coating composition having reduced tendency to crack and of improved solids content is obtained.
