Abstract
A silicone resin is disclosed. The silicone resin is free from carbon atoms. A method of preparing the resin is additionally disclosed. This method comprises reacting a silane compound and a precursor compound, thereby preparing the silicone resin. A composition including the silicon resin and a vehicle is further disclosed. A method of preparing a film with the composition is also disclosed. This method comprises applying the composition including the silicone resin and the vehicle to a substrate to form a layer. This method also includes heating the layer to give the film.
