Abstract
Aqueous coating compositions comprising at least 30 wt. % metal particles, based on the coating composition. The coating composition comprises a silicate-based binding agent. The silicate-based binding agent comprises a silane-modified silicate. The silane-modified silicate is obtained by hydrolysis of a silane in the presence of a silicate at a basic pH.
Claims20
An aqueous coating composition comprising at least 30 wt. % metal particles, based on the coating composition, wherein the coating composition comprises a silicate-based binding agent, wherein the silicate-based binding agent comprises a silane-modified silicate, and wherein the silane-modified silicate is obtained by hydrolysis of a silane in the presence of a silicate at a basic pH.
A method for coating a substrate, the method comprising applying an aqueous coating composition on the substrate, wherein the aqueous coating composition comprises at least 30 wt. % metal particles, based on the aqueous coating composition, and a silicate-based binding agent comprising a silane-modified silicate obtained by hydrolysis of a silane in the presence of a silicate at a basic pH.
