Abstract
A method provides high-vacuum vapor coating methods, with the methods producing novel coating compositions with surprisingly increased performance levels over coatings produced from the same materials under different processing conditions. Compounds of the general formulae II, III and IV, defined herein, can be applied by vapor deposition from a merely compacted, rather than fused or sintered porous matrix source with improved performance, even where the same chemicals are used in the coating, at the same coating temperatures. The generally useful materials include silanes and siloxanes, and siloxazanes of formulae I, II, III and IV.
