Abstract: The invention relates to a coating that is produced from a thermally curable, aqueous coating material on an organic basis, and that contains colloidally dispersed metallic bismuth. The invention further relates to the use thereof as anti-corrosive coating on metal substrates.
Abstract: A crosslinker for polymerizing a film-forming material including an alkyl or aromatic compound comprising at least two functional groups reactive with a film-forming resin and at least one pendent group having a nonionic metal coordinating structure. Coating compositions can include a film-forming material and the crosslinker. The coating compositions can be used to coat a substrate, such as a metal substrate. Applied coating layers on substrates can be cured to form coating films.

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.
Abstract: Film-forming materials include nonionic metal coordinating structures. Nonionic metal coordinating structures can coordinate metals, such as metal catalysts and metal substrates. Example film-forming materials can be the product of a poly-functional epoxide and a nucleophilic ligand having a nonionic metal coordinating structure, or the product of a poly-functional alcohol and an electrophilic ligand having a nonionic metal coordinating structure.
