A method for forming a multilayer paint film comprising the steps of forming an uncured film on a substrate with a cationically depositable paint on a substrate, further coating an aqueous paint on the uncured film of the electrodeposited film in a wet-on-wet manner, and then curing with heating the both films,

Method for forming a paint film

Disclosed is an automotive coating composition comprising (i) a basal resin which is either (a) a copolymer containing a specific polysiloxane macromonomer having two or more functional groups selected from the class consisting of hydroxyl and alkoxy groups per molecule and a number average molecular weight of 400 to 100,000 and an oxirane group-containing vinyl monomer as comonomer units or (b) a mixture of a polymer (I) containing said polysiloxane macromonomer as an essential monomer unit and a polymer (II) containing an oxirane group-containing vinyl monomer as an essential monomer unit and (ii) a chelate compound selected from the class consisting of aluminum chelate compounds, titanium chelate compounds and zirconium chelate compounds.

Process for coating a metallic substrate

A thermosetting powder resin based water-slurry coating composition prepared by dispersing water insoluble thermosetting resin particles and an adduct of a structurally symmetrical diol having a molecular weight of from 90 to 300 with ethylene oxide or propylene oxide, or a mixture thereof in an aqueous medium. The composition provides improvements in the anti-sedimentation properties and redispersibility of particles, and consequently in the extended storage stability and application performance thereof. The composition is applied to form a film with excellent smoothness, gloss, water resistance, moisture resistance, corrosion resistance, etc., without developing any pinholing and cratering by solvent popping, and checking on film formation by heating.
