Abstract
This invention pertains to a method for producing crack-free, insoluble, greater than 1.25 .mu.m thick coatings from hydrogen silsesquioxane resin compositions. The method for producing the coating comprises applying a fillerless hydrogen silsesquioxane resin composition onto a substrate and thereafter heating the hydrogen silsesquioxane resin at a temperature of less than 500.degree. C. for a controlled period of time to produce the crack-free coating having a thickness of greater than 1.25 .mu.m. The resins may be cured in an inert or oxygen containing environment.
