    摘要: A coating composition and a method for coating metallic substrates, such as aircraft components exposed to elevated temperatures and/or oxidative conditions. The coating composition includes an aqueous mixture having about 2 vol % to about 50 vol % organosilane, about 0.3 to about 25 vol % metal alkoxide, and about 0.1 to about 30 vol % organic complexing agent. The coating composition may be deposited on a metallic substrate and cured to form a sol-gel coating on the surface of the substrate that is adherent to the substrate, and oxidation and discoloration resistant.

    摘要: A method of imparting hydrophilicity to a surface of a material, which includes providing a base material having a surface; applying and chemically fixing a siloxane oligomer represented by Chemical Formula 1 to the surface of the base material to form a siloxane-modified surface; and applying a glycidol compound represented by Chemical Formula 2 to the siloxane-modified surface; and carrying out a reaction therebetween to form an organosiloxane coating having a N,N-bis(hydroxyalkyl)aminoalkyl group: wherein R1, R2, and R3 are the same or different and are each independently hydrogen or a C1 to C3 alkyl group, A is a single bond or a C1 to C5 alkylene group, and n ranges from 2 to 30; wherein each R is the same or different, and is as defined herein, and L is a substituted or unsubstituted C1 to C3 alkylene group.
