A coating/sealant system that includes a coating and a sealant deposited over at least a portion of the coating, in which the coating includes a reaction product formed from reactants comprising a phosphated epoxy resin and a curing agent, and the sealant includes a sulfur-containing polymer.

Coating/sealant systems, aqueous resinous dispersions, and methods of electrocoating

Disclosed are methods for treating metal substrates that include contacting the metal with pretreatment compositions comprising: (a) a group IIIB metal, a group IVB metal and/or a group VB metal; and (b) a rheology modifier composition.

Coating/sealant systems, aqueous resinous dispersions, methods for making aqueous resinous dispersions, and methods of electrocoating

An electrodepositable coating composition comprising (i) a film-forming polymer, (ii) a corrosion inhibitor, and (iii) a silane that does not contain an ethylenically unsaturated double bond.

Electrodepositable coating composition comprising silane and yttrium

Disclosed are methods for passivating metal substrates, including ferrous substrates, such as cold rolled steel and electrogalvanized steel. The methods comprise the steps of autodepositing copper, silver, a IIIB metal and/or IVB metal onto at least a portion of the substrate, and simultaneously and/or immediately subsequently electrophoretically depositing on the substrate a curable, electrodepositable coating composition; wherein the copper, silver, IIB metal and/or IVB metal and the curable, electrodepositable coating composition are both contained within a single bath composition. The present invention also relates to coated substrates produced by the above methods.

Process for applying a lead-free coating to untreated metal substrates via electrodeposition

Disclosed are electrodepositable coating compositions containing a polymer prepared from the polymerization of an ethylenically unsaturated monomer having a heterocyclic ring containing at least one ring nitrogen atom bonded to a vinyl group or a mixture of monomers comprised of such a monomer, the compositions further including contaminants capable of forming defects in the electrodeposited coating surface. The polymer is present in an amount effective to abate formation of the surface defects caused by the contaminants. A method of electrocoating a conductive substrate using the electrodepositable coating compositions of the invention is also disclosed.
