Abstract: This invention relates to a process for coating glass or ceramic articles, typically glass bottles, pre-coated with a surface treating agent, of the type comprising applying on the articles a first or basic layer of a silane, and then a layer of a crosslinkable film-forming material comprising a levelling agent, and then crosslinking said layer of film-forming material, wherein the levelling agent is selected from nonionic fluoroalkyl esters, epoxidized fatty acids derivatives, silicone oils and mixtures thereof.This process provides a coating with good appearance and adhesion properties.

Abstract: Process for the preparation of a coating for glass and ceramic surfaces, comprising applying a first layer of a coating composition consisting of a hydroxylated material selected from hydroxylated polyesters, polyetherpolyols, polycaprolactone-polyols and hydroxylated polyesterdiisocyanate adducts, and of a cross-linking agent; thermally cross-linking said first layer; and applying a surface layer of a coating composition consisting of a film-forming material selected from hydroxylated polyesters, optionally modified epoxy resins and acrylic resins, and of a cross-linking agent; and thermally cross-linking the resulting surface layer.
