  • Siloxane coating process for metal or ceramic substrates
    Patent number: 5492730
    Abstract: A novel polymer-coated carbon, metal, or ceramic substrate is coated with an aromatic polysiloxane liquid coating solution polymerized to have non-linear, ladder silicon to oxygen bonding. A carbon, metal, or ceramic layer or substrate coated with the aromatic polysiloxane liquid polymer provides enhanced thermal protection and oxidative stability. The novel aromatic polysiloxane liquid polymer-coated carbon, metal, or ceramic substrate preferably includes a non-linear, ladder aromatic polysiloxane polymer-coated carbon, metal, or ceramic substrate such as provided by polyphenylsiloxane polymer having the general formula R.sub.n SiO.sub.(4-n)/2, wherein R comprises phenyl radical, and n has an average value of about 0.95 to 1.05.
    Type: Grant
    Filed: June 23, 1994
    Date of Patent: February 20, 1996
    Assignee: Aluminum Company of America
    Inventors: Willy M. Balaba, George H. Armstrong, Suzanne Kauffman, Princewill N. Anyalebechi
  • Siloxane coating process for carbon or graphite substrates
    Patent number: 5358747
    Abstract: A polymer-coated carbon is coated with an aromatic polysiloxane liquid coating solution polymerized to have non-linear, ladder-like silicon to oxygen bonding. Carbon fiber or fabric coated with aromatic polysiloxane liquid polymer provides enhanced thermal protection and oxidative stability. The aromatic polysiloxane liquid polymer-coated carbon preferably includes a non-linear, ladder-like aromatic polysiloxane polymer-coated carbon such as provided by polyphenyl-siloxane polymer having the general formula R.sub.n SiO.sub.(4-n)/2, wherein R comprises phenyl radical, and n has an average value of about 0.95 to 1.05.
