Patent ID: 8405233

Claim:
A flexible barrier film having a thickness of from greater than zero to less than 2,000 nanometers and a water vapor transmission rate of no more than 1×10 −2 g/m 2 /day at 22° C. and 47% relative humidity, wherein said flexible barrier film is formed from a composition, which comprises: (A) a multi-functional acrylate; and (B) the reaction product of: (1) an alkoxy-functional organometallic compound having the general chemical formula M(OR) 4 wherein M is selected from a silicon atom, a zirconium atom and a titanium atom, and each OR is an independently selected alkoxy group; and (2) an alkoxy-functional organosilicon compound having the general chemical formula X a Si(OR 1 ) b wherein each X is an independently selected monovalent organic radical; each OR 1 is an independently selected alkoxy group; a is 1, 2, or 3; b is 1, 2, or 3; and a+b=4; and (3) water in an amount sufficient to ensure said reaction product (B) does not gel and a precipitate does not form therefrom.
