Abstract
The present invention relates to hydrogen silsesquioxane resin (H-resin) fractions derived from an extraction process using one or more fluids at, near or above their critical state. These fractions can comprise narrow molecular weight fractions with a dispersity less than about 3.0 or fractions useful for applying coatings on substrates. The invention also relates to a method of using these fractions for forming ceramic coatings on substrates.
