Improved cathodic electrocoating composition compounded with latex binder.

摘要

Improved cathodic electrocoating compositions comprising an aqueous suspension of synthetic, cation-active, film-forming latex particles are characterized by at least one of the following: a) a Tg of at least 20 DEG ; b) a latex gel content not substantially above 10%; and/or c) being practically free from amino monomer and initiator fragments. Such compositions have excellent deposition properties and result in coated metal substrates having improved gloss, adhesion surface characteristics and durability.
