ABSTRACT:
Disclosed are electrodepositable coating compositions containing novel polysiloxanes which are the reaction product of a polysiloxane containing silicon hydride and at least one material which contains one or more unsaturated bonds capable of undergoing hydrosilylation reaction. The electrodepositable coating compositions can be anionic or cationic electrodepositable coatings and are resistant to cratering. Also disclosed is a method of electrocoating a conductive substrate using the electrodepositable coating compositions of the invention. Novel low molecular weight polysiloxanes having pendant groups which contain unsaturated bonds capable of undergoing hydrosilylation reaction are also disclosed.
