Abstract:
1. A method for producing a polymer sleeve for mounting on a mandrel to form a blanket cylinder for use in an electrophotographic process, the method comprising the steps of: a. producing a sleeve having a sidewall of a polymer selected from the group consisting thermoplastic, thermoset and elastomeric polymers, rigid polyurethanes and blends thereof, the sleeve having an inner diameter from about 1 to about 20 percent less than the outer diameter of the mandrel; and b. coating the sleeve with an outer coating comprising a ceramer containing polyurethane and tetraethoxyorthosilicate, the polyurethane having a molecular weight from about 20,000 to about 80,000 with the polyurethane and the tetraethoxyorthosilicate being present in a weight ratio from about 1.8 to about 2.3.
