It has been found that the thermally induced (175 degrees C), peroxide catalyzed cure of filled siloxane films in an inert atmosphere results in well-cured elastomers with mechanical properties superior to similar samples which have been thermally cured at elevated temperatures (240 degrees C). Peroxide volatility, however, has presented a significant problem. In 8.5 - 10.0 x 10/-3/ inch films, peroxide is rapidly lost during the standard curing process which involves heating to 180 degrees C in ovens which require a high positive pressure of nitrogen to maintain an inert atmosphere. Fuser hot rolls spray-coated with silica-filled or organic-filled (0.
