Title
(EN) IMPROVED CATHODIC ELECTROCOATING COMPOSITION COMPOUNDED WITH LATEX BINDER
(FR) COMPOSITION AMELIOREE D'ELECTRO-REVETEMENT CATHODIQUE COMBINE AVEC UN LIANT DE LATEX
Abstract
(EN)
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 20o; 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.
(FR)
Compositions améliorées d'électro-revêtement cathodique comportant une suspension aqueuse de particules de latex synthétiques, cationiquement actives et filmogènes, et caractérisées par au moins l'une des conditions suivantes: a) un Tg d'au moins 20o, b) une teneur en gel de latex qui n'est pas sensiblement supérieure à 10% et/ou c) être pratiquement exempt de monomères amino et de fragments initiateurs. De telles compositions possèdent d'excellentes propriétés de sédimentation et résultent en des substrats métalliques enduits dotés d'une brillance, d'une surface d'adhérence et d'une résistance améliorées.
