Weatherable Compositions Useful As Coatings, Method, And Articles Coated Therewith

US Patent:
6350521, Feb 26, 2002
Filed:
Dec 22, 1999
Appl. No.:
09/469703
Inventors:
Mao Chen - Evansville IN
James Edward Pickett - Schenectady NY
Karen Kueck Webb - Ballston Lake NY
Gregory Ronald Gillette - Clifton Park NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
B32B 2736
US Classification:
428412, 528196
Abstract:
Thermoplastic substrates subject to color instability and loss of physical properties resulting from exposure to ultraviolet radiation, such as polycarbonate, are coated with a protective coating comprising at least one thermoplastic acrylic polymer such as poly(methyl methacrylate) in combination with two ultraviolet absorbing compounds: a substituted resorcinol such as 4,6-dibenzoylresorcinol and a silylated substituted resorcinol such as 2-(3-triethoxysilylpropyl)-4,6-dibenzoylresorcinol. The silylated substituted resorcinol is used in a minor proportion effective to improve solubility and compatibility of the substituted resorcinol.

Method Of Preparing Curable Coating Composition From Alcohol, Colloidal Silica, Silylacrylate And Multiacrylate Monomer

US Patent:
4491508, Jan 1, 1985
Filed:
Jan 21, 1983
Appl. No.:
6/459905
Inventors:
Daniel R. Olson - Schenectady NY
Karen K. Webb - Ballston Lake NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
C08F23008, C08F 250, C08G 7718
US Classification:
20415913
Abstract:
UV curable coating compositions are provided based on the use of photoinitiator with the hydrolysis product of silylacrylate and aqueous colloidal silica. The UV curable silicone coating compositions also can contain polyfunctional acrylate. The UV curable hardcoat composition can be applied onto various substrates, for example, a polycarbonate substrate, and thereafter cured under UV radiation to produce adherent and abrasion resistant coated articles.

Process For Restoring Discharded Silicone-Polycarbonate Parts

US Patent:
5384159, Jan 24, 1995
Filed:
Sep 22, 1993
Appl. No.:
8/124884
Inventors:
Gregory R. Gillette - Clifton Park NY
Karen K. Webb - Ballston Lake NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
B32D 3500
US Classification:
427140
Abstract:
A process is provided for reclaiming rejected polycarbonate articles, such as an automotive headlamp-lens having a thermoplastic acrylic primer and a defective silicone hardcoat. The silicone hardcoat can be selectively removed with an aqueous alkaline bath treatment. The treated polycarbonate article can be recovered with the thermoplastic acrylic primer remaining substantially intact; the article can be restored by treatment with a silicone hardcoat.
