Abstract: Film-forming materials include resins and/or crosslinkers having a —Si(OR)3 group. Film-forming resins can include epoxy, acrylic, polyurethane, polycarbonate, polysiloxane, polyvinyl, polyether, aminoplast, and polyester resins. A process to produce a film-forming resin includes reacting various polymers to incorporate a pendent group comprising a —Si(OR)3 group. Film-forming resins can be used in methods of producing coating compositions. Coating compositions can be used to coat a substrate, such as a metal substrate, by electrodeposition Applied coatings containing the film-forming resins can be cured to form crosslinked films on substrates.
