Abstract
An alkoxyhydridosiloxane resin composition comprising ROSiO siloxane units and HSiO siloxane units wherein R is an alkyl group having 10 to 28 carbon atoms, wherein the alkoxyhydridosiloxane resin contains an average from 5 to 40 mole percent silicon bonded alkoxy groups, and wherein the alkoxyhydridosiloxane resin contains an average of at least 45 mole percent silicon bonded hydrogen atoms. While not represented by the structure, the resins may also contain a small number of atoms which have either 0 or 2 hydrogen atoms attached thereto and/or a small number of SiC groups such as CH SiO or HCH SiO groups. These resins are useful for forming nanoporous silicone resin coatings having low dielectric constant coatings useful for electrical insulating coatings on electronic devices.
