Patent number: 5994424Abstract: A free-radical curable polish composition is described. The composition can be applied and cured as an ultra thin film on finished surfaces to provide enhanced chemical and mar resistance. The composition comprises an aqueous emulsion including an olefin-functional polymer or an olefin-functional prepolymer, and a silicone or silicone copolymer preferably with photoinitiators for UV and EB cure. The polish/emulsion can be applied, for example, to wet the surface of nitrocellulose lacquer wood finishes. The polish wet surface is first wiped to remove excess polish and thereafter exposed to UV radiation to provide a thin, polymerized protective film.Type: GrantFiled: February 12, 1998Date of Patent: November 30, 1999Assignee: Lilly Industries, Inc.Inventors: Eugen Safta, Frank Chen, Greg Muselman, James V. Mirante, Danny R. Linthicum

Patent number: 5948484Abstract: An an improved process for surface modification of solid substrates, such as polymers and carbon-based materials, is disclosed. The preferred process comprises three steps: a first activation step wherein reactive hydrogen groups are formed in a surface layer of a polymeric or carbon-based material; a second silylation step wherein the reactive hydrogen groups are reacted with a silylating agent to form silicon-containing groups; and a third stabilization step wherein an upper portion of the activated, silylated layer is oxidatively converted to a silicon and oxygen enriched surface layer. The process can be performed using materials not having pre-existing reactive hydrogen groups or precursor groups. Modified materials according to the present invention have improved properties, such as erosion resistance and oxygen and water barrier properties, and are potentially useful in numerous industries, such as aerospace and packaging.Type: GrantFiled: June 5, 1997Date of Patent: September 7, 1999Inventors: Yuri Gudimenko, Jasha I. Kleiman, Grant R. Cool, Zelina A. Iskanderova, Roderick C. Tennyson
