Siloxane coatings for aluminum reflectors

摘要

A novel polymer-coated reflector aluminum is coated with an aromatic polysiloxane liquid coating solution polymerized to have non-linear, ladder silicon to oxygen bonding. A metal layer or substrate coated with the aromatic polysiloxane liquid polymer provides enhanced planarization and total reflectivity. The novel aromatic polysiloxane liquid polymer-coated metal preferably includes a non-linear, ladder aromatic polysiloxane polymer-coated aluminum metal sheet such as provided by polyphenylsiloxane polymer having the general formula RnSiO(4-n)/2, wherein R comprises phenyl radical, and n has an average value of about 0.95 to 1.05.
